Telehealth Billing in 2026: Codes, Modifiers, and Payer Rules

Telehealth billing requires three elements to be correct simultaneously: the CPT code for the service provided, the Place of Service (POS) code, and the appropriate modifier. Get any one wrong and the claim is denied — and telehealth denials are among the most common preventable denials in 2026, accounting for 8 to 12% of all denials at practices with significant telehealth volume. The CPT code is straightforward — you bill the same code you would bill for an in-person visit (99213, 99214, 90834, etc.). The complexity lives in the POS code and modifier. Medicare uses POS 10 (telehealth provided to patient in their home) with modifier 95 for synchronous audio-video visits. Some commercial payers use POS 02 (telehealth provided to patient at a facility). Others use the same POS as in-office (POS 11) with modifier 95 or the older GT modifier overlaid. Some Medicaid managed-care plans use POS 02 with no modifier. There is no universal standard across the 900-plus active insurance products in the US market. The POS code also affects reimbursement rates: Medicare pays the same rate for POS 10 and POS 11 for most telehealth-eligible codes, but some commercial payers reduce reimbursement by 10 to 20% for telehealth visits compared to in-office visits. Know your payer contracts before assuming telehealth payment parity.

Medicare has made most pandemic-era telehealth flexibilities permanent for 2026 under the Consolidated Appropriations Act and subsequent CMS rulemaking. The permanent rules include: POS 10 for patients receiving telehealth at home (no geographic restrictions for most services — the pre-pandemic requirement that patients be in rural health professional shortage areas has been eliminated), modifier 95 for synchronous audio-video visits, audio-only allowed for certain behavioral health services using modifier 93 (including 90834, 90837, and 90839 for established patients), and FQHCs and RHCs can serve as distant-site providers for telehealth services. Key limitations that remain: Medicare requires an in-person visit within 12 months of the initial telehealth encounter for mental health services, and at least annually thereafter, with exceptions for patients in rural areas or those with documented barriers to in-person care. The in-person requirement does not apply to non-mental-health telehealth services. Telehealth-eligible CPT codes are published on the CMS Telehealth Services List, updated quarterly. As of 2026, over 250 CPT codes are telehealth-eligible under Medicare, including E/M codes (99202-99215), behavioral health codes (90791-90853), and selected procedural codes for remote patient monitoring (99453-99458). Medicare does not reduce reimbursement for telehealth versus in-person visits for most eligible codes, making Medicare one of the most telehealth-friendly payers from a financial standpoint.

Every commercial payer maintains its own telehealth policy, and these policies change frequently — sometimes quarterly. As of early 2026, the major payers' rules are as follows. Aetna: uses modifier 95 with POS 02 for audio-video telehealth. Covers audio-only for behavioral health using modifier 93 and CPT codes 99441-99443 for telephone E/M. Reimburses at in-network rates with payment parity for most telehealth-eligible services in states that mandate parity. BCBS: varies significantly by state plan — Anthem BCBS uses modifier 95 with POS 02, while independent BCBS plans like BCBS of Texas and BCBS of Michigan each have their own modifier and POS requirements. Some BCBS plans still accept GT modifier; others reject it. Always check the specific state plan's provider manual. UnitedHealthcare: generally accepts POS 02 with modifier 95 for audio-video. UHC has expanded telehealth coverage significantly but does not mandate payment parity in all states — reimbursement may be 85 to 95% of in-office rates depending on the state and service type. Cigna: requires modifier 95 with POS 02. Cigna limits telehealth to audio-video for most medical services but covers audio-only for behavioral health with modifier 93 in states that mandate audio-only coverage. Humana: uses modifier 95 with POS 10 or 02 (both accepted). Humana generally provides payment parity for telehealth services. The only reliable approach is to check each payer's current telehealth policy before submitting claims. Maintain a payer-specific telehealth billing matrix and update it quarterly.

Audio-only (telephone) visits have more restrictive coverage and lower reimbursement than audio-video visits. The clinical rationale is straightforward: payers argue that without visual assessment, the quality of the encounter is reduced. But for many behavioral-health patients, elderly patients without technology access, and patients in rural areas with poor internet connectivity, audio-only is the only viable telehealth modality. Medicare allows audio-only for established behavioral-health patients using modifier 93 on therapy codes (90834, 90837) and crisis codes (90839). Audio-only E/M visits are billed using the telephone E/M codes 99441 (5-10 minutes, ~$28), 99442 (11-20 minutes, ~$51), and 99443 (21-30 minutes, ~$75) rather than the standard office E/M codes. These reimburse substantially less than standard E/M — a 99443 pays $75 compared to $128 for a 99214. Commercial payer audio-only policies vary widely: Aetna covers audio-only for behavioral health and E/M. BCBS varies by state plan — some cover audio-only broadly, others restrict it to behavioral health only. UHC covers audio-only behavioral health in most states but limits audio-only E/M to specific circumstances. Cigna covers audio-only behavioral health in states that mandate it. Some commercial payers do not cover audio-only at all for any service type. Always verify coverage before billing audio-only visits — denials for non-covered audio-only services are among the most common telehealth-related denials.

Beyond Medicare and commercial payer policies, each state has its own telehealth laws that add another layer of billing requirements. These laws affect which provider types can deliver telehealth (some states restrict telehealth to specific licensure categories), whether a pre-existing in-person relationship is required before the first telehealth visit (most states have eliminated this requirement, but a handful still enforce it for prescribing controlled substances), informed consent requirements (over 30 states require documented patient consent for telehealth services, ranging from verbal consent noted in the chart to written consent forms), prescribing limitations (DEA rules and state medical board regulations govern telehealth prescribing of controlled substances — the permanent rules for 2026 impose new in-person examination requirements for Schedule II prescriptions), and Medicaid telehealth coverage (each state's Medicaid program has its own telehealth rules covering eligible services, eligible provider types, reimbursement rates, and audio-only policies). For practices providing telehealth across state lines, the billing rules follow the patient's location at the time of service — not the provider's location. A physician licensed in New York treating a patient in Florida via telehealth must follow Florida's telehealth laws and bill using Florida-specific payer rules.

Beyond correct coding, several strategies help telehealth-heavy practices maximize revenue. First, use the highest-appropriate E/M level — telehealth visits involving medication management, review of lab results, and care coordination frequently support 99214 or 99215 under MDM-based coding, but many providers default to 99213 for telehealth because they perceive the visit as simpler than in-office. If the medical decision making supports the code, bill it regardless of modality. Second, bill G2211 (visit complexity add-on, $16.04 per visit) on telehealth E/M visits where the physician manages the patient's ongoing relationship for a serious or complex condition — the add-on is not restricted to in-person visits. On 40 telehealth visits per week, G2211 adds $33,363 annually. Third, capture all billable services delivered during the telehealth encounter: remote patient education, care coordination time (99487-99489 for complex chronic care management), and prolonged service time (99417 when the visit exceeds the base code's time threshold). Fourth, implement text-to-pay or online payment collection for telehealth copays — collecting before the session starts prevents patient-balance A/R from accumulating.

Telehealth billing complexity is one of the primary reasons practices outsource their billing. The combination of payer-specific POS codes, modifier requirements, audio-only rules, state telehealth laws, and payment-parity variations creates a billing environment where even experienced in-house billers make costly errors. Go Medical Billing tracks telehealth rules across all 50 states and all major payers. Our billing system maintains a continuously updated telehealth-modifier matrix that automatically applies the correct POS code and modifier combination for each payer, each state, and each service type. When a payer changes its telehealth policy — which happens quarterly for some carriers — our system is updated within one business day of the policy change notification. For our telehealth-heavy clients (behavioral health practices, telepsychiatry groups, and multi-state primary-care practices), we eliminate telehealth-specific denials almost entirely. Our telehealth clean-claim rate exceeds 99% because the POS, modifier, and service-type validation happens automatically before every claim is submitted.
