Telehealth is no longer a pandemic workaround. It is a standard way to deliver care, and it changes how claims are coded, documented and paid. Telehealth medical billing follows the same revenue cycle as an in-person visit, but each step has extra rules: which technology was used, where the patient and provider were, and which modifier and place-of-service code go on the claim. A small mistake on any of these can mean a denial.
This guide covers what changes on the claim, the areas that cause the most denials, and how to keep your telehealth revenue compliant. If you would rather hand the work to a team that does this every day, you can book a consultation with Billing Care Assistant.
How telehealth changes the billing process
Traditional billing workflows assume an in-person visit with predictable documentation. Virtual visits break those assumptions in three ways:
- The technology matters. A real-time video visit, an audio-only call and a store-and-forward review are coded differently, and payers pay them differently.
- Location matters. The patient’s location, the provider’s location and the originating site rules can all affect eligibility and payment.
- Payers differ. Medicare, Medicaid and commercial plans each set their own telehealth rules, and many change them from year to year.
That is why a claim that was paid last year can be denied this year with no change on your side. Check each payer’s current policy rather than assuming one set of rules applies to all of them.
Coding telehealth visits: CPT codes, modifiers and place of service
CPT and E/M codes
Most telehealth visits are billed with the same evaluation and management (E/M) codes as in-person visits, and the claim signals that the visit was virtual. Some services also have their own codes, such as virtual check-ins and remote patient monitoring. Review your code list against the current Medicare Physician Fee Schedule and the AMA’s CPT updates, and confirm which codes each payer accepts for telehealth.
Modifiers
Modifiers tell the payer how the service was delivered. The two you will see most often are:
- Modifier 95 for synchronous (real-time, audio and video) telehealth services, where the payer asks for it.
- Modifier 93 for audio-only services, where the payer asks for it.
Payers do not all use the same modifier rules. Some want 95, some want a place-of-service code instead, and some behavioral health services use their own modifiers. Check the policy for each payer before you submit.
Place of service
The place-of-service (POS) code shows where the patient was during the visit. Telehealth commonly uses POS 02 (telehealth provided somewhere other than the patient’s home) and POS 10 (telehealth provided in the patient’s home), but the right code depends on the payer and the year. A wrong POS code is one of the most common reasons telehealth claims are denied or paid at the wrong rate.
Audio-only visits
Many payers will pay for audio-only visits in some situations, but the conditions are tighter than for video. Document why video was not used, for example that the patient had no video-capable device or no reliable connection, and record that the patient agreed to an audio-only visit. Use the audio-only modifier your payer requires. Without that note, an audio-only claim is easy for a payer to deny or recoup in an audit.
Remote patient monitoring
Remote patient monitoring (RPM) is one of the fastest-growing telehealth services, and one of the hardest to bill. It covers device setup, patient education, data review and follow-up, often over many days or weeks. Each part has its own code and its own documentation and time requirements, such as the number of days of data collected and the minutes of clinical time. Billing and clinical staff need to track these together, or services get performed and never billed.
Common telehealth billing mistakes
- Using the wrong modifier or POS code. Check the payer’s current policy, not last year’s claim.
- Missing documentation. The note should say that the visit was by telehealth, the technology used, where the patient and provider were, and who took part.
- Billing a service the payer does not cover by telehealth. Verify coverage and eligibility before the visit.
- Skipping prior authorization. Payer rules for virtual care vary, and an authorization gap can sink an otherwise clean claim.
- Ignoring state rules. Providers who see patients across state lines need to follow licensing and telehealth rules in the patient’s state. RHIhub and Telehealth.HHS.gov are good starting points.
Compliance and fraud prevention
Rapid growth in virtual care has also drawn attention from auditors. The usual problems are billing for visits that did not happen, billing a higher level of service than the note supports, and not meeting the technical requirements of a code. To protect your practice:
- Verify patient identity and record consent at the start of each visit.
- Make sure the note supports the level of service billed and the medical necessity of the visit.
- Audit a sample of telehealth claims on a regular schedule.
- Use secure, HIPAA-compliant platforms. See our guide to HIPAA-compliant AI tools if you are using AI with patient data.
Technology that helps
Good tooling cuts telehealth errors. Look for an EHR or telehealth platform that sends the visit documentation to billing automatically, a claim scrubber that checks modifiers and POS codes before submission, and real-time eligibility checks that confirm telehealth coverage for each patient. These do not replace coding knowledge, but they catch simple errors before the claim goes out.
Keep up with changing rules
Telehealth rules change often, and some of the pandemic-era flexibilities have been extended, changed or ended on different dates. Before each plan year, review the changes for Medicare, your largest commercial payers and your state Medicaid program.
Conclusion
Telehealth adds revenue opportunities, from video visits to audio-only care and remote patient monitoring, but it also adds coding and compliance risk. Practices that get the modifiers, place of service and documentation right, and review payer policy regularly, see fewer denials and faster payment.
