RTM Billing Guidelines 2026: How to Document, Submit & Get Fully Reimbursed

Introduction: RTM Billing Guidelines 2026

Why Most RTM Claims Get Paid Less Than They Should

Remote Therapeutic Monitoring reimbursement in 2026 is not primarily a coding challenge — it is a documentation and workflow challenge. Clinics that know the CPT codes but skip the underlying CMS requirements learn this the hard way when explanation of benefits letters arrive with partial payments, pending statuses, or outright denials.

The RTM billing landscape in 2026 has three distinct layers of complexity:

• Federal CMS rules set the floor for what Medicare must cover

• Medicare Advantage and commercial payer policies sit above that floor — sometimes higher, often inconsistent

• State-level Medicaid rules vary independently and are the most unpredictable of all

Mastering RTM billing means understanding all three layers simultaneously while building workflows that generate audit-ready documentation for every claim you submit. This guide walks through each layer, the five documentation fields that determine whether a claim is paid or denied, the most common denial reasons (and exactly how to fix them), and the end-to-end billing timeline from patient consent to payment posting.

Payer-by-Payer Reimbursement Overview

Traditional Medicare (Part B)

Traditional Medicare is the most permissive RTM payer and sets the baseline for all other coverage discussions. Under the CY 2026 Physician Fee Schedule Final Rule, Medicare covers all RTM CPT codes including the three new 2026 additions (98984, 98985, and 98979) under Part B for eligible providers.

Coverage requirements Medicare will enforce in 2026:

• Device must be FDA-cleared and specifically designed to monitor musculoskeletal, respiratory, or cognitive behavioral therapy conditions

• Patient must provide documented consent before monitoring begins

• Monitoring data must be automatically collected by the device (not manually entered by the patient)

• Services must be ordered by a physician, NPP, or treating therapist within their scope of practice

• Only one provider can bill RTM management codes (98979, 98980, 98981) for a given patient in a given calendar month

Modifier requirement: Physical therapists, occupational therapists, and speech-language pathologists billing RTM under Medicare must append the appropriate therapy modifier:

• GP modifier: Physical therapy services

• GO modifier: Occupational therapy services

• GN modifier: Speech-language pathology services

Without the correct modifier, Medicare will reject the claim as provider type mismatch.

Patient cost-sharing: Standard Medicare Part B cost-sharing applies (20% after deductible). Patients with supplemental insurance or Medigap coverage typically pay $0 out-of-pocket, which removes a significant barrier to enrollment.

Medicare Advantage (MA) Plans

Per the 2024 Physician Fee Schedule Final Rule, Medicare Advantage plans are required to provide at least the same level of coverage as Traditional Medicare for remote monitoring services. However, the practical reality is more complicated.

What MA plans must cover: All RTM CPT codes that Medicare covers, including new 2026 codes, at rates at or above Medicare rates.

What actually happens in practice: Some MA plans — most notably United Healthcare — have used policy language to justify reduced coverage or prior authorization requirements that effectively limit access. CMS has signaled enforcement intent, but providers should be prepared to:

• Verify individual MA plan RTM coverage before enrollment (not just Medicare eligibility)

• Appeal denials citing the 2024 PFS mandate that MA match Medicare coverage

• Document denial patterns by plan for potential escalation to CMS or advocacy organizations

Reimbursement rates: MA plans typically reimburse between 95–102% of Medicare rates for RTM codes, with some plans negotiating higher rates in value-based contracts.

Commercial PPO/HMO Insurance

Commercial payer RTM coverage has expanded significantly since 2022 but remains inconsistent across carriers. The critical variable is the individual plan's Local Coverage Determination (LCD) equivalent — some commercial plans have formally adopted RTM coverage; others still classify remote monitoring as "investigational" or require additional authorization steps.

Coverage tiers among commercial payers:

Reimbursement rates: Commercial PPO plans average 120–150% of Medicare rates. HMO plans typically run 110–130% of Medicare rates. This commercial premium makes payer mix analysis critical — a practice with a 50% commercial book of business can see RTM revenue meaningfully exceed Medicare-only projections.

Best practice: Run a commercial payer audit quarterly. Contract language changes, and coverage policies that said "no" in 2024 may say "yes" in 2026 as RTM becomes more mainstream.

Medicaid

Medicaid RTM coverage is the most fragmented category, varying state-by-state based on individual Medicaid managed care organization (MCO) contracts and state agency decisions.

General Medicaid RTM landscape in 2026:

• Approximately 28 states have adopted some form of remote monitoring coverage in Medicaid fee-for-service programs

• Medicaid MCOs (managed care organizations) may have coverage policies that differ from the state fee-for-service program

• Reimbursement typically runs 70–90% of Medicare rates for states with coverage

Practical approach: Contact your state Medicaid program directly or verify through your billing clearinghouse before enrolling Medicaid patients in RTM. Do not assume Medicaid coverage based on Medicare eligibility.

The 5 Documentation Fields Every RTM Claim Needs

CMS and virtually every payer conducting RTM audits in 2026 look for these five elements before approving payment. Missing even one creates both a denial risk and a compliance exposure.

Field 1: Patient Consent — With Exact Date and Method

The consent requirement for RTM is non-negotiable. CMS requires documented evidence that the patient was informed about and agreed to RTM participation before monitoring began.

What the documentation must show:

• Patient name and date of birth

• Date consent was obtained (must be on or before first monitoring day)

• Method of consent (written signature, electronic signature, verbal with staff attestation)

• Whether cost-sharing was discussed (required for Medicare patients)

• Staff name who obtained consent

Common error: Dating consent at the end of the month when billing is processed rather than the actual enrollment date. This is a compliance violation auditors catch immediately because the device transmission log shows data before the consent date.

Best practice template language: "On [date], patient [name] was informed about Remote Therapeutic Monitoring services, the FDA-cleared device to be used, the data that will be collected, how it will be used in their care, and their right to withdraw consent at any time. Patient consented to participation. Cost-sharing of approximately [amount] per month was discussed. Consent obtained by [staff name]."

Field 2: Medical Necessity with ICD-10 Linkage

Every RTM claim must be tied to a specific diagnosis that justifies remote monitoring. Generic notes ("patient needs monitoring") are a primary target for denial on audit. Documentation must show:

• Primary ICD-10 code matching an RTM-eligible condition

• A clear statement of why RTM is clinically appropriate for this patient and this diagnosis

• How RTM data will be used to make clinical decisions (not just collected passively)

Strong vs. weak medical necessity statements:

Weak: "RTM ordered for post-op monitoring."

Strong: "Patient is 4 weeks post ACL reconstruction with a history of poor home exercise adherence (self-reported). RTM using FDA-cleared MSK monitoring device ordered to track home exercise program completion frequency, range of motion progress, and pain level trends. RTM data will be reviewed weekly to adjust HEP intensity and determine readiness for next functional phase of rehabilitation."

The second example demonstrates clinical reasoning, expected data type, and how data will influence decisions — the three things auditors look for.

Field 3: Device Identification and Data Transmission Log

The RTM device used must be specifically designed and FDA-cleared (or exempt) for therapeutic monitoring of the relevant condition. Fitness trackers, standard smartwatches, and generic mobile app health logs do not qualify, because they rely on patient action rather than automated system-captured data.

Documentation must include:

• Device name and manufacturer

• FDA clearance status (or exemption classification)

• Date device was provided or app was set up with patient

• Data transmission log showing unique calendar days of data received

• System-generated timestamp records (not manually entered dates)

This is where audit exposure concentrates. If your platform cannot produce a timestamped, system-generated log of the specific days data transmitted, you cannot defend the claim. Self-attestation by clinical staff ("patient told us they used it 12 days") does not satisfy the requirement.

Field 4: Clinical Activity Log with Time Stamps

For treatment management codes (98979, 98980, 98981), you must document every minute of clinical time with start and end timestamps, the activity performed, and the staff member performing it.

Required elements per time entry:

• Date and time (start and stop)

• Staff name and credential

• Activity type (data review, care plan adjustment, patient communication, care coordination)

• Clinical findings and decisions made

• For 98979/98980: Confirmation of real-time interactive communication this calendar month

Example compliant time entry:"2/14/2026, 10:05–10:19 AM (14 minutes). Reviewed 11-day HEP adherence trend: patient completing 72% of prescribed exercises. Noted decrease in adherence days 8-10 correlating with reported work schedule change. Adjusted HEP to two abbreviated sessions per day rather than one longer session. Phone call with patient 10:08–10:14 AM: discussed adherence data, confirmed schedule modification, patient verbalized understanding and agreement."

This single entry documents: time, staff, data reviewed, clinical interpretation, decision made, and the real-time communication — all five elements auditors look for.

Field 5: Plan of Care Integration

RTM cannot be a standalone service disconnected from the patient's treatment plan. CMS expects documentation showing that RTM is formally integrated into the plan of care:

• RTM mentioned in the initial evaluation or episode plan of care

• Monitoring goals tied to functional outcomes (not just "track compliance")

• RTM findings referenced in progress notes

• RTM data cited in any treatment plan modifications

The integration test: If you removed all RTM documentation from a patient's chart, would the clinical notes still make sense as a standalone episode? If yes, you have not integrated RTM into the plan of care — you have bolted it on, which is exactly what post-payment audits look for.

Most Common RTM Denial Reasons and Fixes

Denial 1: Missing or Pre-Dated Patient Consent

Trigger: Consent document absent from chart, or consent date falls after first transmission date.

Fix: Implement enrollment-triggered consent capture in your intake workflow. Consent must be captured and timestamped before any device data is collected. Use digital signature tools that auto-stamp date and time and push to the patient record immediately.

Denial 2: Insufficient Days of Data Transmission

Trigger: Claim submitted for 98977 (16+ days) but audit reveals only 14 unique transmission days. Or claim submitted for 98985 (2–15 days) with only 1 day of data.

Fix: Build automated threshold alerts into your monitoring platform. Set alerts at day 13 of the billing period to prompt patient outreach for patients who have not yet reached 16 days. For patients clearly trending short-period, proactively adjust the billing target to 98985 (2–15 days) rather than waiting for denial.

Denial 3: Time Documentation Insufficient for Management Code

Trigger: 98980 billed but chart shows only a general note with no time stamps, or time total cannot be verified to reach 20 minutes.

Fix: Enforce start/stop documentation as a non-negotiable field in your RTM management workflow. No timestamp, no claim. Some practices implement a system where management codes cannot be queued for billing unless the time tracking module is completed with specific timestamps.

Denial 4: No Real-Time Interactive Communication Documented

Trigger: 98979 or 98980 billed but no synchronous communication with patient or caregiver is documented for the calendar month.

Fix: Flag each patient's monitoring record with a "Real-Time Contact Required" status that does not clear until a phone, video, or synchronous portal interaction is logged. Make this the final step before management code billing is triggered.

Denial 5: Wrong or Missing Therapy Modifier

Trigger: PT, OT, or SLP submits RTM claim without GP, GO, or GN modifier respectively.

Fix: Build modifier auto-population into your billing workflow based on rendering provider credential. This should be a system rule, not a manual field, to eliminate the risk of human omission.

Denial 6: Duplicate Claim — Same Patient, Same Code, Same Period

Trigger: Two providers at the same practice both bill 98980 for the same patient in the same month, or provider switches mid-month and both submit.

Fix: Establish an RTM "ownership" rule in your practice management system: the first provider who submits a management code claim for a patient in a given calendar month "locks" that code for the period. Second submissions are blocked before reaching the clearinghouse.

The RTM Billing Timeline: Consent to Payment

Day 0 — Enrollment and ConsentPatient is identified as RTM-eligible. Consent conversation completed, digital signature captured with auto-timestamp. Device provided or app onboarding completed. Monitoring episode begins. ICD-10 confirmed. RTM integrated into plan of care documentation.

Days 1–15 — Active Monitoring, Threshold TrackingDevice transmits data. Platform logs each unique transmission day automatically. Clinical staff review dashboard for alerts. Alert fires at Day 13 if patient is at risk of falling short of 16-day threshold (prompts outreach or prepares for 98985 billing instead).

Day 15–28 — Clinical Management ActivityTreating provider reviews accumulated data, documents time with start/stop timestamps, documents clinical decisions made, and ensures at least one real-time interactive communication occurred this calendar month. Management code queued for billing.

Day 30 (or last day of 30-day period) — Code Selection and Claim

Generation Platform counts final transmission days:

• 2–15 days → 98985 (MSK) or 98984 (respiratory)

• 16+ days → 98977 (MSK) or 98976 (respiratory)

  
  

  Platform counts management time and queues:

• 10–19 min → 98979

• 20+ min → 98980 (plus 98981 if additional 20-min block applies)

  
  

  Claims batch generated with all required modifiers.

Days 31–45 — Claim Submission and Clearinghouse Processing

Claims submitted to clearinghouse with supporting documentation attached. Clearinghouse runs eligibility and payer-specific rule validation. Clean claims transmitted to payer.

Days 45–75 — Adjudication and Payment

Most Medicare claims adjudicate within 14–30 days of receipt. Commercial payers may take 30–45 days. ERA (Electronic Remittance Advice) received, payment posted, any denials flagged for appeal.

Days 75–90+ — Denial Management

Denied claims reviewed against denial reason code. Corrected claims resubmitted within payer's timely filing window (typically 90–180 days from date of service). Appeals submitted with supporting documentation for complex denials.

Average clean claim payment timeline: 28–45 days from date of service for Medicare; 45–75 days for commercial payers.
