E/M Coding for Telehealth Visits: The 2026 Rules Every Provider Must Know

Telehealth went from a niche billing category to roughly 30% of all E/M encounters in under three years. But the coding rules for virtual visits are still misunderstood by the majority of physicians and billing staff — and those misunderstandings are costing practices real money.

The AMA 2021 MDM guidelines changed how telehealth E/M coding works. If you’re still using pre-2021 logic, you’re almost certainly coding telehealth visits incorrectly.

How Total Time Works for Telehealth Under AMA 2021

The biggest change: total time on the date of encounter now includes more than face-to-face time with the patient. For telehealth E/M visits, countable time includes:

Preparing to see the patient (reviewing the chart, prior results, referral notes)
The synchronous video or audio encounter itself
Ordering tests, referrals, and prescriptions
Communicating results to the patient (portal messages, follow-up calls)
Documenting the clinical encounter
Care coordination that doesn’t require a separate E/M code

This is identical to in-person time rules. The key distinction: only activities performed on the date of service count. If you review labs two days before the telehealth appointment, that time does not count toward the telehealth visit total.

Time Thresholds: The Codes and Their Ranges

For established patient office/outpatient telehealth visits (99211–99215), the time-based thresholds are:

99212: 10–19 minutes total time
99213: 20–29 minutes total time
99214: 30–39 minutes total time
99215: 40–54 minutes total time

For new patient telehealth visits (99202–99205):

99202: 15–29 minutes
99203: 30–44 minutes
99204: 45–59 minutes
99205: 60–74 minutes

Critical rule: you can code by time OR MDM — whichever yields the higher code. Many telehealth visits involve significant pre-visit chart review and post-visit coordination that push total time well above what the face-to-face portion alone would suggest. If you’re only coding by MDM for telehealth, you’re likely leaving money on the table.

Modifiers: 95 vs. GT vs. Place of Service

Modifier confusion is the top reason telehealth claims get denied. Here’s what you actually need:

Modifier 95 is the current standard for synchronous telehealth services. It tells the payer the service was rendered via real-time audio/video. Medicare and most commercial payers accept modifier 95.

Modifier GT (via interactive audio/video) was the older CMS standard. As of 2024, CMS considers it obsolete — modifier 95 has replaced it. However, some state Medicaid programs and a handful of commercial payers still require GT. Check your payer’s specific requirements.

Place of Service (POS) codes:

POS 10 — Telehealth provided in the patient’s home. This is the most common POS for telehealth in 2026.
POS 02 — Telehealth provided when the patient is at a healthcare facility (originating site).

Using the wrong POS code can trigger a lower reimbursement rate or outright denial. POS 10 typically reimburses at the non-facility rate (higher), while POS 02 may reimburse at the facility rate (lower) depending on the payer.

Audio-Only Visits: What You Can and Cannot Bill

CMS extended audio-only telehealth coverage through 2026 for established patients when video is not feasible. The eligible codes are limited:

99212–99215 for E/M services (audio-only, established patients)
Behavioral health codes 90832, 90834, 90837 (audio-only permitted)
99441–99443 for telephone E/M (separate code set, lower reimbursement)

Audio-only requires modifier 93 (synchronous telecommunications) AND documentation explaining why video was not available. “Patient preference” alone is generally insufficient — you need a clinical or technical reason.

New patient visits are not eligible for audio-only E/M under Medicare. Some commercial payers are more permissive, but verify before billing.

Documentation Traps That Cause Telehealth Denials

The five most common telehealth documentation failures:

1. Missing consent documentation. Most payers require documented patient consent for telehealth. This can be verbal (documented in the note) or written. CMS requires consent at least once per year, documented in the medical record. Missing consent = denial on audit.

2. No technology statement. Your note should state the technology used: “Visit conducted via HIPAA-compliant synchronous video platform.” Some payers require naming the platform. Omitting this detail is an audit flag.

3. Incorrect time documentation for time-based coding. If you code by time, you must document total time AND a brief statement of what time was spent on. “Total time 35 minutes including chart review, video encounter, and care coordination” is sufficient. Just writing “35 min” without context is not.

4. Billing telehealth and in-person on the same day. If a patient has a telehealth visit in the morning and comes in for an in-person visit the same afternoon, you cannot bill both as separate E/M encounters unless they are for clearly distinct problems with modifier 25 on the second visit. This is a common audit trigger.

5. Telehealth for procedures. E/M coding applies to cognitive services delivered via telehealth. You cannot bill procedure codes (except specific exceptions like remote patient monitoring) for telehealth encounters. If a telehealth visit involves a procedure discussion, bill the E/M and note the planned procedure for the in-person follow-up.

State Parity Laws: Where Telehealth Pays the Same as In-Person

As of 2026, 42 states have some form of telehealth payment parity law, but “parity” varies significantly:

Full parity states (e.g., CA, NY, CO, VA) require commercial payers to reimburse telehealth at the same rate as in-person for equivalent services.
Partial parity states may require coverage but allow different reimbursement rates.
No parity states leave reimbursement entirely to payer discretion.

Medicare reimburses telehealth E/M at the same rate as in-person when POS 10 is used (non-facility rate). This is a significant change from pre-2020 policy.

How AI Catches Telehealth Coding Errors

Telehealth introduces a unique set of coding variables — modifier selection, POS codes, time documentation requirements, consent documentation — that are easy to get wrong under daily volume pressure.

CodeItRight’s AI analyzer handles telehealth-specific coding rules automatically. Paste your telehealth note, and it:

Calculates both MDM-based and time-based codes, flagging which is higher
Identifies missing documentation elements specific to telehealth claims
Produces audit-ready rationale that references AMA 2021 MDM criteria
Flags gap analysis opportunities where documentation supports a higher code

For telehealth-heavy practices, getting the time documentation right on every visit is the difference between leaving $30,000–$80,000 on the table annually and capturing it.

FAQ: Telehealth E/M Coding

Q: Can I bill a 99215 for a telehealth visit?
A: Yes. There is no code-level restriction on telehealth E/M. If your MDM or total time meets the 99215 threshold, bill it. The documentation requirements are identical to in-person.

Q: Does asynchronous messaging count as telehealth?
A: Store-and-forward (asynchronous) is a separate category with its own codes and rules. Standard E/M telehealth codes require synchronous (real-time) interaction. Patient portal messages do not qualify as telehealth visits.

Q: What if the video drops mid-visit and we switch to phone?
A: If a clinically sufficient portion of the visit was conducted via video, you can still bill with modifier 95. Document the technical issue and the transition to audio. If the entire visit was audio-only from the start, use modifier 93 and ensure you meet audio-only eligibility requirements.

Q: Do I need a separate consent for every telehealth visit?
A: CMS requires documented consent annually. Most commercial payers follow the same standard. Some state Medicaid programs require per-visit consent. Check your specific payer mix.
