Coding Telehealth Services
Assigns telehealth-specific codes with correct place of service (POS), modifier application (95, GT, FQ, FR, G0), technology requirements, and originating/distant site billing. Covers synchronous audio-video visits, audio-only services, remote patient monitoring, asynchronous (store-and-forward) services, and interprofessional consultations.
Why This Skill Exists
Telehealth coding rules change frequently — CMS releases updates through annual fee schedule rules, transmittals, and interim final rules. The post-pandemic permanent telehealth expansions differ significantly from temporary flexibilities. Key complexities include: POS code selection (02 vs. 10 vs. original POS), modifier requirements varying by payer, geographic and originating site restrictions for Medicare, audio-only eligibility limits, and the distinction between telehealth services and remote evaluation/monitoring services. Incorrect POS or missing modifiers result in claim denials; incorrect service-type classification creates compliance risk.
Checkpoint A — Intake
Questions to Confirm Before Starting
- What type of telehealth service was provided? (synchronous audio-video, audio-only, store-and-forward, remote monitoring)
- What technology platform was used? Is it HIPAA-compliant with real-time audio-video capability?
- Where was the patient located during the encounter? (home, clinic, hospital, nursing facility)
- Where was the provider located? (office, home, hospital)
- Is the service on the CMS Telehealth Eligible Services List (for Medicare)?
- What payer covers this service? (Medicare FFS, Medicare Advantage, Medicaid, commercial)
- What is the patient's state of residence? (state telehealth parity laws vary significantly)
Documents Required
- Encounter note documenting the telehealth service (same documentation standards as in-person)
- Technology/platform documentation (audio-video vs. audio-only)
- Patient consent for telehealth (required by most states and Medicare)
- Patient location documentation (state and setting)
- Provider location and licensure in the patient's state
- CMS Telehealth Eligible Services List (current calendar year)
- Payer-specific telehealth policies
Step 1 — Determine the Service Category
Classify the telehealth service type — each has different coding rules.
Synchronous audio-video telehealth:
- Real-time interactive audio and video communication between patient and provider.
- Uses the same CPT/HCPCS codes as in-person services (E/M, psychotherapy, consultations, etc.).
- Must be on the CMS Telehealth Eligible Services List for Medicare reimbursement.
- Requires interactive audio AND video — audio-only does not qualify (with limited exceptions).
Audio-only services:
- 99441: 5–10 minutes of medical discussion (telephone E/M).
- 99442: 11–20 minutes.
- 99443: 21–30 minutes.
- Medicare allows audio-only for certain behavioral health services (90832–90838, 90839, 90845) and E/M services in limited circumstances for established patients.
- Audio-only eligibility varies significantly by payer and state.
Remote evaluation and management:
- G2010: Remote evaluation of recorded video/images submitted by an established patient (store-and-forward). Not a real-time service.
- G2012: Virtual check-in — brief communication (5–10 minutes) via synchronous technology initiated by an established patient. Not a separately billable E/M.
- 99421–99423: Online digital E/M service (patient portal communication over 7-day period). Time-based: 5–10 min, 11–20 min, 21+ min cumulative.
Remote Patient Monitoring (RPM):
- 99453: Initial setup and patient education on RPM devices (one-time).
- 99454: Device supply with daily recording and programmatic alerts, per 30 days.
- 99457: RPM treatment management, first 20 minutes per calendar month.
- +99458: Each additional 20 minutes per calendar month.
- 99091: Collection and interpretation of physiologic data, 30+ minutes per 30 days (cannot bill with 99457 in the same month).
Step 2 — Select the Correct Place of Service
POS determines payment rates and modifier requirements.
Medicare POS rules (post-PHE permanent policy):
- POS 02 — Telehealth provided other than in patient's home: Patient is at an originating site (clinic, hospital, SNF, etc.). Facility rate applies.
- POS 10 — Telehealth provided in patient's home: Patient is at home. Non-facility rate applies.
- When the patient is at home, use POS 10. When at a healthcare facility, use POS 02.
- For audio-only services, use POS 02 or 10 based on patient location.
Commercial payer POS rules:
- Some commercial payers require the original POS (11 for office, 22 for hospital outpatient) with modifier 95 to indicate telehealth.
- Others use POS 02/10 following the Medicare model.
- Check payer-specific policy before claim submission.
Originating site requirements (Medicare):
- For services still subject to geographic restrictions, the originating site must be in a rural HPSA or non-MSA county.
- Mental health and behavioral health telehealth services were permanently exempted from geographic restrictions (effective 2025).
- An originating site facility fee (Q3014) can be billed by the facility where the patient is located (not the distant site provider).
Step 3 — Apply Telehealth Modifiers
Select the correct modifier based on service type and payer.
- Modifier 95: Synchronous telehealth service via real-time audio and video. CMS-preferred modifier for Medicare claims. Applied to the procedure code on the professional claim.
- Modifier GT: Telehealth via interactive audio and video telecommunications system. Used by some commercial payers instead of or in addition to modifier 95.
- Modifier FQ: Telehealth service provided using audio-only communication technology. Required by Medicare for eligible audio-only services.
- Modifier FR: Supervising practitioner present through real-time audio-video communication technology for services furnished by a resident. Used in teaching physician scenarios.
- Modifier G0: Telehealth service for diagnosis, evaluation, or treatment of symptoms of an acute stroke. Applied to acute stroke telehealth consultations.
- Modifier 93: Audio-only services (used by some state Medicaid programs instead of FQ).
Key modifier rules:
- Do NOT append telehealth modifiers to RPM codes (99453–99458) — RPM is not a telehealth service.
- Do NOT append telehealth modifiers to virtual check-ins (G2010, G2012) or e-visits (99421–99423).
- Medicare requires modifier 95 for all telehealth-eligible CPT codes and modifier FQ for audio-only eligible services.
Step 4 — Validate Medicare Telehealth Eligibility
Confirm the service is on the CMS Telehealth Eligible Services List.
- CMS publishes an updated list annually (effective January 1) with additions from the Medicare Physician Fee Schedule Final Rule.
- Services on the list include: office/outpatient E/M (99202–99215), subsequent hospital care (99231–99233), psychiatric services (90791–90899), certain consultation codes (not recognized by Medicare FFS but relevant for MA plans), and specific procedure codes.
- Services NOT on the list cannot be billed as Medicare telehealth — they must be provided in-person.
- Some services were added temporarily during the PHE and may not be permanent — verify against the current list.
- Medicare Advantage plans may cover additional telehealth services beyond the FFS list — check the MA plan's supplemental benefits.
Step 5 — Code Remote Patient Monitoring
Apply RPM coding rules for chronic condition monitoring.
- Eligibility: Patient must have a chronic condition requiring monitoring (e.g., hypertension, diabetes, CHF, COPD).
- Minimum data requirement: RPM requires at least 16 days of data collection within a 30-day period for 99454 to be billable.
- 99453 (initial setup): One-time code for setting up the RPM device and educating the patient. Billed once per episode of care.
- 99454 (device supply/data transmission): Billed per 30-day period. Requires daily recording or programmatic alerts.
- 99457 (treatment management): Requires at least 20 minutes of clinical staff time per calendar month interacting with the patient about the RPM data. Must include live interaction (phone, video, or in-person).
- +99458 (additional time): Each additional 20-minute increment beyond the first 20 minutes.
- RPM can be furnished by clinical staff under general supervision of the billing provider.
- RPM is NOT telehealth — it does not require real-time audio-video and is not subject to telehealth POS/modifier rules.
Checkpoint B — Review
Quality Audit
Guidelines
- Follow CMS Telehealth Eligible Services List (updated annually in the Medicare Physician Fee Schedule Final Rule)
- Apply CMS Medicare Claims Processing Manual Chapter 12 §190 for telehealth billing requirements
- Reference CMS MLN Matters articles for telehealth policy updates and clarifications
- Follow state telehealth parity laws for commercial payer coverage requirements
- Apply HIPAA security requirements for telehealth technology platforms
- Never bill a telehealth service as an in-person visit without telehealth modifiers — this misrepresents the service
- Mark with [VERIFY] any telehealth service where eligibility, POS, or modifier selection is uncertain
- Include disclaimer that telehealth coding rules change frequently and payer-specific policies must be verified at the time of billing
