Telehealth Medical Billing Overview
Telehealth utilization increased 3,800 percent between 2019 and 2021. It has not returned to pre-pandemic levels. As of 2024, telehealth accounts for roughly 13 to 17 percent of all outpatient visits in primary care and behavioral health settings. That volume creates a significant billing problem. Most practices are still submitting telehealth claims with errors that cost them 12 to 22 percent of their eligible reimbursement. The rules changed fast and they keep changing. Practices that have not updated their billing protocols since the COVID-19 public health emergency ended in May 2023 are leaving money on the table on every single claim.
The core issue is this: telehealth billing is not a single set of rules. Medicare has its own framework, Medicaid rules vary by state, and each commercial payer has its own coverage policy. BCBS, UnitedHealthcare, Aetna, Cigna, and Humana each define originating site, eligible providers, covered services, and reimbursement rates differently. A claim that pays correctly for one payer will be denied by another if the modifier or place of service code is not adjusted. This variation is not stable: payer policies on telehealth are updated frequently, and a billing team that was current six months ago may be operating on outdated rules today.
Common Billing Challenges in Telehealth
- Wrong place of service codes: POS 02 applies to telehealth when the patient is not at home. POS 10 applies to telehealth provided to a patient in their home, which was established by CMS in 2022. Using POS 02 for home-based visits suppresses reimbursement because facility rates apply instead of non-facility rates, and the difference is often 20 to 35 percent per claim.
- Missing or incorrect modifiers: Modifier 95 signals a synchronous telemedicine service rendered via real-time interactive audio and video. Modifier GT is still required by some payers. Modifier 93 covers audio-only services when video is unavailable. Applying the wrong modifier triggers automatic downcoding or denial.
- Audio-only coverage gaps: Medicare covers audio-only telehealth for behavioral health under specific conditions. Commercial payers are inconsistent. Billing audio-only visits without confirming payer coverage first results in blanket denials that are difficult to appeal without documentation of patient circumstances.
- Originating site fee billing errors: Facility fees under HCPCS code Q3014 are only billable when the patient is at an eligible originating site. Billing this fee for home-based visits or for patients at non-qualifying sites is a claim error that generates denials and potential overpayment liability.
Key CPT Codes for Telehealth Billing
- 99213: Office or other outpatient visit, established patient, low medical decision making; frequently billed for telehealth with modifier 95 and POS 10 or 02
- 99214: Office or other outpatient visit, established patient, moderate medical decision making; highest volume telehealth E/M code in primary care and internal medicine
- 99422: Online digital evaluation and management service, established patient, for 11 to 20 minutes of medical discussion
- 90837: Psychotherapy, 60 minutes; one of the most common telehealth codes in behavioral health, covered by most payers for synchronous video visits
- G2212: Prolonged office or other outpatient evaluation and management service; add-on to primary E/M code for visits exceeding time thresholds, applicable in telehealth settings
Revenue Cycle Considerations for Telehealth
Telehealth A/R days average 32 to 44 days across high-volume practices. Denial rates for telehealth claims run 15 to 28 percent depending on payer mix and billing accuracy. The biggest revenue leakage point is place of service miscoding. A practice seeing 200 telehealth visits per week at $125 average reimbursement loses approximately $5,200 to $8,750 per week from POS errors alone if 20 percent of claims are underpaid due to facility versus non-facility rate differences.
Medicare telehealth waivers that extended coverage beyond geographic restrictions expired when the public health emergency ended. Some extensions were made permanent under the Consolidated Appropriations Act and subsequent legislation. Others reverted. Staying current on which services remain covered for which patient populations requires active monitoring of CMS transmittals and MLN Matters articles. Practices that do not have a dedicated billing team tracking these changes are billing blindly.
State telehealth parity laws now exist in over 40 states, requiring commercial payers to reimburse telehealth visits at the same rate as in-person visits for covered services. However, enforcement and plan compliance vary. Practices that accept below-parity reimbursement without auditing their telehealth payment rates against in-person rates may be collecting less than they are legally entitled to. A systematic comparison of telehealth versus in-person payment rates by payer and service type identifies these gaps and supports contract renegotiation or parity law complaints where applicable. Behavioral health telehealth billing carries additional documentation requirements under Medicare and Medicaid, including confirmation that interactive video was the modality used and precise recording of session time to justify the CPT code selected.
