CPT Code 98985: The MSK Monitoring Code That Changes Everything in 2026

For three years, physical therapy practices billing Remote Therapeutic Monitoring faced a revenue cliff that had nothing to do with clinical outcomes. A patient who transmitted data for 15 days in a 30-day period generated $0 in device supply reimbursement — not because the monitoring lacked value, but because CMS required 16 days minimum to bill CPT 98977.

Starting January 1, 2026, that cliff disappeared.

CPT 98985 — the new short-period musculoskeletal device supply code — created a billing pathway for patients with 2 to 15 transmission days in a 30-day period. The change is not incremental. It is structural. And for physical therapy clinics managing acute injuries, post-surgical transitions, or patients with inconsistent engagement patterns, it represents one of the most significant RTM billing expansions since the program launched in 2022.

This article explains exactly what CPT 98985 covers, why the 2-day threshold matters operationally and financially, what documentation CMS requires, and how the code changes revenue math for previously unbillable patient scenarios.

What CPT Code 98985 Covers: Device Supply for 2–15 Days of MSK Monitoring

Official CPT Code Descriptor

CPT 98985: Remote therapeutic monitoring (e.g., therapy adherence, therapy response, digital therapeutic intervention); device(s) supply for data access or data transmissions to support monitoring of musculoskeletal system, 2 to 15 days in a 30-day period.

This is a supply-only code. It reimburses the provision and programming of FDA-cleared digital devices or software that monitor non-physiologic musculoskeletal data — specifically:

Therapy adherence (home exercise completion rates, exercise frequency)
Therapy response (pain scores, functional assessments, ROM progress)
Digital therapeutic interventions (guided exercise videos, real-time feedback prompts)

CPT 98985 does not include clinician management time. That is billed separately using management codes (CPT 98979, 98980, or 98981).

What Qualifies as "Device Supply"

The term "device(s) supply" encompasses:

FDA-cleared software platforms (mobile apps with 510(k) clearance for MSK monitoring)
Wearable devices with MSK-specific data capture (goniometers, activity trackers with FDA clearance)
Web-based platforms accessed via patient portal with FDA clearance
Automated data transmission systems (devices that sync data without manual patient entry)

Critical requirement: The device or software must carry FDA 510(k) clearance specifically for musculoskeletal therapeutic monitoring. General wellness apps, fitness trackers without FDA clearance, and EHR patient portals without FDA device classification do not qualify.

Musculoskeletal Focus: What Data Counts

Post-Surgical Orthopedic Recovery:

Total knee replacement (TKR) rehabilitation
ACL reconstruction recovery
Rotator cuff repair adherence
Spinal fusion post-op monitoring

Chronic MSK Conditions:

Chronic low back pain exercise adherence
Osteoarthritis home program compliance
Chronic neck pain functional tracking
Tendinopathy rehabilitation response

Acute Injuries:

Ankle sprain recovery
Muscle strain rehabilitation
Post-fracture mobility restoration
Sports injury return-to-play tracking

Note: Respiratory conditions use the parallel code CPT 98984 (same 2–15 day structure, but for respiratory monitoring). The two codes are condition-specific and cannot be combined for the same patient in the same period.

Why the 2-Day Threshold is Revolutionary: From Cliff to Bridge

The 16-Day Cliff Problem (Pre-2026)

Before January 1, 2026, RTM device supply billing required 16 days minimum of data transmission within a 30-day period to bill CPT 98977. The financial consequence was binary:

16+ days: Bill CPT 98977 at $40.08 (2026 national average)
1–15 days: Bill $0.00

This created predictable revenue loss scenarios:

Scenario 1: Post-Op Patient Discharged Early

A patient receives TKR and begins home exercise monitoring. After 14 days of consistent data transmission, their surgeon clears them for full weight-bearing and discharges from physical therapy. The PT practice provided 14 days of device monitoring, reviewed data, and made clinical decisions. Revenue captured: $0.

Scenario 2: Acute Injury with Rapid Resolution

A patient with acute ankle sprain uses RTM for 12 days while inflammation resolves. Monitoring captured exercise adherence and pain trends that informed clinical progression. Revenue captured: $0.

Scenario 3: Partial Month Engagement

A patient is enrolled in RTM on day 18 of a calendar month. They transmit data for 13 days before the 30-day billing period closes. Clinical value delivered. Revenue captured: $0.

The 2-Day Bridge (2026 Forward)

CPT 98985 eliminates the cliff by creating a billing pathway for 2 to 15 days of monitoring:

2–15 days: Bill CPT 98985 at $40.08
16+ days: Bill CPT 98977 at $40.08
0–1 days: No device supply billing (clinical threshold not met)

The financial logic changes from binary (all or nothing) to tiered (capture value proportional to engagement).

Revised Scenario 1: Post-op patient discharges after 14 days. Bill CPT 98985. Revenue: $40.08 (was $0).

Revised Scenario 2: Acute ankle sprain resolves after 12 days. Bill CPT 98985. Revenue: $40.08 (was $0).

Revised Scenario 3: Patient enrolls mid-month, transmits 13 days. Bill CPT 98985. Revenue: $40.08 (was $0).

The 2-day minimum threshold is clinically meaningful — it ensures at least two unique data points (baseline + follow-up) while remaining operationally achievable for even brief monitoring episodes.

Why This Matters for PT Clinics Specifically

Physical therapy practices see higher rates of short-duration RTM episodes compared to chronic disease management (where RPM dominates). Three patient categories drive this pattern:

Acute injuries (ankle sprains, muscle strains) — 10–21 day episodes common
Post-surgical patients discharged early — insurance authorization ends before 16-day threshold
Flare-up management (chronic back pain exacerbations) — 7–14 day monitoring windows

Before 2026, these categories represented lost RTM revenue despite genuine clinical utility. CPT 98985 converts that lost opportunity into billable service.

Reimbursement Rate & Payment Mechanics

2026 National Average Reimbursement

According to the CMS 2026 Physician Fee Schedule Final Rule:

CPT 98985 National Average Reimbursement:

Non-APM (Merit-based Incentive Payment System - MIPS): $40.08
APM (Advanced Alternative Payment Model): $40.28

These rates are national averages. Actual reimbursement varies by:

Geographic locality (Medicare Administrative Contractor region)
Facility vs. non-facility setting
Participation in quality programs (MIPS, APM)

Rate Parity with CPT 98977: The 2–15 day code (98985) reimburses at the same rate as the 16+ day code (98977). CMS valued both codes identically because device supply cost does not scale linearly with transmission days — the primary cost is platform access, not per-day data volume.

Billing Frequency Rules

CPT 98985 may be billed:

Once per 30-day period per patient
By one provider (billing ownership must be assigned to avoid duplicate claims)
In combination with management codes (98979, 98980, 98981) if management time thresholds are met

CPT 98985 may NOT be billed:

Concurrently with CPT 98977 (same patient, same 30-day period)
More than once per 30-day period (even if patient has multiple conditions)
Without FDA-cleared device (will result in denial for device eligibility failure)
Alongside RPM codes (99453, 99454, 99457, 99458) for the same patient in the same calendar month

The 30-Day Period Definition

CMS defines the billing period as a rolling 30-day period measured from the date of device supply, not calendar month boundaries. This distinction matters for enrollment timing:

Example:

Device supplied to patient: February 15
30-day period: February 15 – March 16
Transmission days counted: Any days within that window
If patient transmits data on 10 days between Feb 15 – Mar 16 → Bill CPT 98985
Next 30-day period begins March 17

Commercial Payer Coverage

While Medicare coverage is established through the CMS Final Rule, commercial payer policies for CPT 98985 vary significantly:

UnitedHealthcare, Aetna, Cigna: Reviewing policies as of Q1 2026; many following Medicare guidelines
Blue Cross Blue Shield plans: Vary by state; some adopted immediately, others require prior authorization
Self-insured employer plans: Coverage dependent on plan design

Recommendation: Verify coverage with each commercial payer before enrolling patients. Do not assume Medicare coverage translates automatically to commercial plans.

Documentation Requirements: What CMS Auditors Verify

CPT 98985 requires specific documentation elements to support billing. Claims submitted without these elements face systematic denials or audit recoupment.

Mandatory Documentation Elements

1. Device Information

What to document:

Device or software name (e.g., "Limber Health MSK Monitoring App")
FDA 510(k) clearance number (e.g., "K123456")
Date device supplied to patient
Device assignment confirmation (screenshot or platform log showing patient activation)

Why it matters: Auditors verify FDA clearance. If the device does not carry 510(k) clearance for MSK monitoring, the claim denies regardless of clinical documentation quality.

2. Transmission Day Count

What to document:

Exact transmission dates (not just total count)
System-generated report showing transmission log
Confirmation that count falls within 2–15 day range

Example acceptable documentation:

"RTM data transmitted on 10 unique days within 30-day period (March 5, 7, 9, 11, 13, 15, 17, 19, 21, 23). System report confirms transmission count. CPT 98985 billed for device supply."

Why it matters: CMS requires verification of transmission day count. Manual estimates ("patient used device approximately 10 days") do not meet audit standards. Use platform-generated reports showing exact dates.

3. Medical Necessity Justification

What to document:

ICD-10 diagnosis code(s) linked to monitoring (e.g., M17.11 - Unilateral primary osteoarthritis, right knee)
Clinical rationale for short-period monitoring (why 2–15 days vs. longer duration)
Connection between monitoring data and treatment plan

Example acceptable documentation:

"Patient with acute R ankle sprain (S93.401A) enrolled in RTM for 12-day monitoring period during acute inflammatory phase. Home exercise adherence and pain score tracking inform progression to weight-bearing activities. Short-period monitoring appropriate for acute injury expected to resolve within 2–3 weeks."

Why it matters: Medical necessity must be patient-specific. Template language ("patient enrolled in RTM for home exercise monitoring") without condition-specific rationale raises audit flags.

4. Device Features Confirmation

What to document:

Scheduled or programmed alert system (proves automatic transmission capability)
Data capture method (automated sync vs. manual patient entry)
Type of data collected (exercise completion, pain scores, functional assessments)

Example acceptable documentation:

"Device programmed with daily alerts at 8:00 AM prompting patient to complete assigned exercises. Adherence data and pain scores automatically transmitted to clinical dashboard upon exercise completion. No manual patient data entry required."

Why it matters: CMS requires devices to have "scheduled or programmed" data transmission capability. Purely manual patient-reported outcomes without automated capture do not qualify.

Documentation Timing Requirements

All documentation elements must be completed before or concurrent with the end of the 30-day monitoring period. Retroactive documentation added after billing submission does not satisfy audit requirements.

Best practice workflow:

Document device supply and FDA clearance at enrollment (Day 1)
Monitor transmission count via platform dashboard throughout 30-day period
At day 30, generate system report confirming transmission count
Document medical necessity and clinical rationale in patient chart
Submit CPT 98985 claim with documentation attached

Common Documentation Errors That Trigger Denials

Error 1: Transmission count does not match system report

Billing team claims 10 days, but system report shows 9 days. Claim denies for failing to meet 2-day minimum (system report takes precedence over manual count).

Error 2: Device FDA clearance not documented

Claim submitted without FDA 510(k) number in chart. Auditor cannot verify device eligibility. Claim denies or gets flagged for recoupment.

Error 3: Overlapping billing periods

Patient enrolled in two separate 30-day periods with partial overlap. Both periods billed CPT 98985. Second claim denies as duplicate.

Error 4: Missing medical necessity narrative

ICD-10 code present, but no explanation of why short-period monitoring was clinically appropriate for this specific patient. Audit recoupment risk increases.

The Revenue Math: Previously Unbillable Patients Now Generate $40.08/Month

The financial impact of CPT 98985 is most visible in patient categories that previously fell below the 16-day threshold. Here are three concrete examples showing before/after revenue calculations.

Example 1: Post-Surgical Patient with Early Discharge

Patient profile:

Total knee replacement (TKR) patient enrolled in RTM at post-op week 1
Transmits data consistently for 14 days
Surgeon clears patient for full weight-bearing at 2-week mark
PT discharges patient from RTM after 14 days

Pre-2026 revenue:

Transmission days: 14 (below 16-day threshold)
Device supply billing: $0.00
Management billing: $0.00 (no device supply = no management billing)
Total RTM revenue: $0.00

2026 revenue with CPT 98985:

Transmission days: 14 (meets 2–15 day threshold)
Device supply (CPT 98985): $40.08
Management time: 15 minutes reviewing data + adjusting exercise progression
Management billing (CPT 98979): $26.00 (10–19 minute tier)
Total RTM revenue: $66.08

Revenue gain per patient: $66.08 (from $0)

If clinic treats 20 post-surgical patients per month who follow this pattern:

Monthly revenue gain: $1,321.60
Annual revenue gain: $15,859.20

Example 2: Acute Ankle Sprain with 10-Day Monitoring

Patient profile:

Acute grade II ankle sprain
Enrolled in RTM for acute phase monitoring (days 3–12 post-injury)
Transmits data for 10 days while inflammation resolves
Graduates to independent home program after 10 days

Pre-2026 revenue:

Transmission days: 10 (below 16-day threshold)
Device supply billing: $0.00
Management billing: $0.00
Total RTM revenue: $0.00

2026 revenue with CPT 98985:

Transmission days: 10 (meets 2–15 day threshold)
Device supply (CPT 98985): $40.08
Management time: 12 minutes reviewing adherence trends
Management billing (CPT 98979): $26.00
Total RTM revenue: $66.08

Revenue gain per patient: $66.08 (from $0)

If clinic treats 15 acute injury patients per month with this pattern:

Monthly revenue gain: $991.20
Annual revenue gain: $11,894.40

Example 3: Chronic Pain Flare-Up (8-Day Monitoring Window)

Patient profile:

Patient with chronic low back pain experiences acute flare
Enrolled in short-term RTM to monitor exercise modification response
Transmits data for 8 days during flare-up period
Returns to baseline home program after symptom resolution

Pre-2026 revenue:

Transmission days: 8 (below 16-day threshold)
Device supply billing: $0.00
Management billing: $0.00
Total RTM revenue: $0.00

2026 revenue with CPT 98985:

Transmission days: 8 (meets 2–15 day threshold)
Device supply (CPT 98985): $40.08
Management time: 18 minutes adjusting exercise intensity based on pain scores
Management billing (CPT 98979): $26.00
Total RTM revenue: $66.08

Revenue gain per patient: $66.08 (from $0)

If clinic treats 10 flare-up patients per month with this pattern:

Monthly revenue gain: $660.80
Annual revenue gain: $7,929.60

Aggregate Impact: 45 Patients Per Month

Combining all three scenarios (20 post-surgical + 15 acute + 10 flare-ups):

Total monthly RTM revenue gain: $2,973.60

Total annual RTM revenue gain: $35,683.20

These patients existed in clinic caseloads before 2026. The clinical work was being done. The monitoring data was being collected and reviewed. The only change: CMS now reimburses for it.

CliniQ RTM Platform: Automatic 98985 Tracking & Code Assignment

The operational challenge with CPT 98985 is not the code itself — it is the administrative burden of tracking transmission days, distinguishing between 2–15 day episodes and 16+ day episodes, and selecting the correct code at billing time.

Manual tracking creates three failure modes:

Under-counting transmission days → Billing 98985 when patient actually qualified for 98977 (leaving money on table)
Over-counting transmission days → Billing 98977 when patient only met 98985 threshold (claim denial)
Missing billing window entirely → Not realizing patient met 2–15 day threshold until after 30-day period closes

CliniQ's RTM platform eliminates all three risks through automated code logic.

How CliniQ Handles CPT 98985 Automatically

1. Real-Time Transmission Day Tracking

CliniQ's dashboard shows cumulative transmission days for each enrolled patient in real time. Clinicians and billing staff see:

Current transmission day count (updates daily)
Days remaining in 30-day billing period
Projected code (98985 vs. 98977) based on current trajectory

No manual counting. No spreadsheet tracking. The system maintains the definitive record.

2. Threshold-Based Code Assignment

At the close of each 30-day billing period, CliniQ's billing engine automatically:

Counts verified transmission days from device logs
Applies code selection logic:
- 2–15 days → CPT 98985
- 16–30 days → CPT 98977
- 0–1 days → No device supply code
Queues the correct code for claim generation

Billing staff review, but do not manually select codes. The system applies CMS logic consistently across all patients.

3. Documentation Package Auto-Generation

For every CPT 98985 claim, CliniQ generates an audit-ready documentation package that includes:

Device FDA clearance confirmation (stored once, attached to all relevant claims)
System-generated transmission log showing exact dates
Billing period dates (e.g., "Feb 15 – Mar 16")
Transmission day count confirmation (e.g., "10 unique transmission days verified")

This package attaches automatically to the claim at submission. Auditors receive complete documentation without manual chart review.

4. Overlap Prevention Logic

CliniQ's system enforces CMS billing rules:

Prevents concurrent 98985 and 98977 billing for same patient in same period
Blocks duplicate 98985 submissions within 30-day window
Flags patients with active RPM enrollment before RTM code generation

These checks happen at code assignment, not after claim submission. Errors are caught before claims leave the system.

Real-World Outcome: 96%+ First-Pass Acceptance Rate

Across CliniQ's active practice network, CPT 98985 claims generated through the automated system achieve 96%+ first-pass acceptance rate from Medicare and commercial payers.

That acceptance rate reflects:

Correct code selection based on verified transmission counts
Complete documentation attached at submission
No overlapping billing period errors
FDA device eligibility confirmed before first claim

The 4% denial rate is not systematic — it is payer-specific edge cases (e.g., individual commercial plans that do not yet cover RTM, patients with coverage gaps). The platform is not generating billing logic errors.

Who Should You Enroll for CPT 98985 Specifically?

Not every RTM-eligible patient is a good fit for short-period monitoring. CPT 98985 serves specific clinical scenarios where abbreviated monitoring aligns with treatment goals.

Ideal Patient Categories for 98985

1. Acute Injury Patients (Expected 7–14 Day Recovery)

Ankle sprains (grade I–II)
Muscle strains (hamstring, quad, calf)
Acute back pain flare-ups
Post-fracture early mobilization

Clinical rationale: Monitoring most valuable during acute inflammatory phase. Once pain stabilizes and patient returns to baseline, ongoing RTM not clinically justified.

2. Post-Surgical Patients Discharged Before 16 Days

TKR patients cleared early by surgeon
Arthroscopic procedures with rapid recovery
Post-op patients with insurance authorization limits (10–14 visits approved)

Clinical rationale: Device supply and monitoring provided during authorized treatment window. Discharge dictated by external factors (insurance, surgical clearance), not RTM program design.

3. Transitional Care Episodes (Bridge Between Phases)

Pre-operative "prehab" programs (8–12 days before surgery)
Post-discharge monitoring before first outpatient PT visit
Short-term monitoring during return-to-sport clearance testing

Clinical rationale: Short-term monitoring fills specific gap in care continuum. Not intended as ongoing program.

4. Trial Enrollment Periods

Patients new to digital health platforms (2-week trial to assess tech comfort)
Assessing patient adherence patterns before committing to full RTM program
Testing home exercise feasibility before designing long-term program

Clinical rationale: Short-period monitoring as evaluation tool. Decision to continue or discontinue made after trial period.

Patients Better Suited for CPT 98977 (16+ Days)

While CPT 98985 expands RTM access, some patients should still target the 16+ day threshold:

1. Chronic MSK Conditions

Chronic low back pain (ongoing adherence monitoring)
Osteoarthritis (long-term exercise program)
Chronic neck pain (extended rehab protocols)

2. Complex Post-Surgical Recovery

Spinal fusion (12+ week protocols)
Complex shoulder reconstruction
Revision surgeries with extended rehab

3. Patients with Consistent Engagement Patterns

High adherence to home programs
Good technology literacy
Strong intrinsic motivation

For these patients, full-duration RTM (16–30 days per billing period, recurring monthly) delivers both better clinical outcomes and higher revenue per patient ($40.08 device + $54.00 management = $94.08 per month vs. $66.08 for short-period).

Implementation Checklist: Adding CPT 98985 to Your RTM Program

If your clinic already bills RTM using CPT 98977, adding CPT 98985 requires minimal workflow changes. The patient enrollment, device supply, and monitoring processes remain identical — only the billing logic and patient selection criteria expand.

5-Step Implementation Checklist

Step 1: Verify Platform Capabilities (Week 1)

Confirm your RTM platform tracks transmission days in real time
Verify platform generates separate reports for 2–15 day vs. 16+ day periods
Test whether billing system can differentiate between 98985 and 98977 thresholds
If platform cannot distinguish automatically, plan manual tracking workflow

Step 2: Train Billing Team on Code Selection Logic (Week 1)

Review CPT 98985 vs. 98977 threshold rules
Practice scenario-based code selection (10 days → 98985, 18 days → 98977)
Emphasize one code per 30-day period rule (cannot bill both)
Train on documentation requirements specific to short-period monitoring

Step 3: Update Patient Enrollment Criteria (Week 2)

Identify patient categories appropriate for short-period monitoring (see "Who Should You Enroll" section above)
Develop clinical guidelines for when to target 2–15 days vs. 16+ days
Train clinical staff on recognizing short-period monitoring opportunities (acute injuries, early discharge, transitional care)

Step 4: Modify Documentation Templates (Week 2)

Add medical necessity language for short-period monitoring rationale
Update device supply notes to include FDA clearance documentation
Create transmission log report template showing exact dates
Build pre-submission checklist specific to 98985 claims

Step 5: Pilot with 10 Patients (Weeks 3–4)

Enroll 10 patients expected to fall in 2–15 day range
Monitor transmission counts throughout 30-day period
Generate first CPT 98985 claims at period close
Track claim acceptance rates and denial reasons
Refine workflow based on pilot feedback

Common Mistakes to Avoid When Billing CPT 98985

Mistake 1: Billing Both 98985 and 98977 in Same 30-Day Period

What happens: Patient transmits data for 8 days in first half of billing period, then 12 days in second half (20 days total). Billing team submits CPT 98985 for first 8 days, then CPT 98977 for full 20 days.

Result: Both claims deny. CMS allows one device supply code per 30-day period. Transmission days are cumulative across the entire period.

Correct approach: Count total transmission days across full 30-day period. If total is 2–15 days → Bill 98985 once. If total is 16–30 days → Bill 98977 once.

Mistake 2: Billing 98985 for Patients with Only 1 Transmission Day

What happens: Patient enrolls, transmits data on enrollment day, then disengages. Billing team submits CPT 98985 claiming "device was supplied."

Result: Claim denies. CPT 98985 requires minimum 2 unique transmission days. Device supply alone without data transmission does not meet threshold.

Correct approach: Monitor transmission count through day 30. If patient only transmits 0–1 days, no device supply code is billable (neither 98985 nor 98977).

Mistake 3: Not Documenting Why Short-Period Monitoring Was Appropriate

What happens: Billing team submits CPT 98985 with ICD-10 code for chronic low back pain. No documentation explains why monitoring ended at 12 days instead of continuing to 16+ days.

Result: Audit flags claim as potential under-utilization. Auditor questions whether monitoring was medically necessary or if patient simply disengaged.

Correct approach: Document patient-specific rationale for short monitoring duration (e.g., "acute flare monitoring during 2-week medication trial" or "patient discharged by physician after 12 days, full recovery achieved").

Mistake 4: Using Non-FDA-Cleared Device and Billing 98985

What happens: Clinic uses general wellness app without FDA 510(k) clearance. App tracks exercise completion. Billing team submits CPT 98985 because patient transmitted data for 10 days.

Result: Systematic denials across all claims. Auditor verifies FDA clearance. Without 510(k) clearance for MSK monitoring, device does not meet CMS definition regardless of data quality.

Correct approach: Verify FDA clearance before enrolling first patient. Only bill RTM codes (98985, 98977, or any other RTM code) if device carries documented 510(k) clearance.

Next Steps: Start Capturing Short-Period RTM Revenue This Month

CPT 98985 is not a future opportunity. It is active as of January 1, 2026. Every eligible patient discharged early, every acute injury that resolves in 10 days, every transitional care episode — these are billable opportunities right now.

The question is not whether your clinic should implement CPT 98985. The question is: how many patients have you already discharged in January and February 2026 who transmitted 2–15 days of data and generated $0 in revenue?

If your RTM platform is not tracking transmission days and auto-selecting between 98985 and 98977:You are manually counting, manually selecting codes, and introducing billing errors at every step. CliniQ's automated code assignment eliminates that risk.

If your billing team is still waiting for "more guidance" on when to use 98985:The guidance is already final. CMS published the code descriptor, reimbursement rate, and billing rules in the 2026 Physician Fee Schedule Final Rule (November 2025). The window for implementation is not future — it is now.

If your clinic has not yet enrolled a single patient targeting CPT 98985:You are leaving an average of $66.08 per patient on the table for every acute injury, early discharge, or transitional care episode you treat.

CliniQ's RTM platform handles CPT 98985 automatically — transmission tracking, code selection, documentation generation, and claim submission — with 96%+ first-pass acceptance rates.
