Detailed Guide by Capline on How to Code for Telehealth
Telehealth is no longer a side service. It is part of normal care delivery now. Federal telehealth data shows that 25% of Medicare fee-for-service users had a telehealth service in 2024, and 95% of HRSA-funded health centers used telehealth to provide primary care in 2024. That scale makes coding accuracy very important. A simple coding mistake can slow payment, trigger a denial, or create audit risk
A telehealth claim can be denied even when the patient received proper care. In many cases, the issue is not the visit itself but how it was documented and coded. If the claim does not clearly show the service, the visit type, and the patient’s location, payment problems can follow.
In this blog, you will learn a clean workflow for telehealth coding, plus the most common rules around codes, modifiers, and place of service, so your claims match how the visit actually happened.
How to code for telehealth the right way?
The safest way is to code in order. Do not start with the modifier. Start with the service.
Step 1: Identify the service family
Ask what really happened during the encounter.
If it were a full visit with assessment and treatment decisions, it may fall into the office or outpatient evaluation and management family. If it were a short patient-initiated communication to decide next steps, it may fit a telehealth virtual check-in code. If the patient sent images or video for later review, that may fit a remote evaluation code instead. The American Medical Association (AMA) includes several Current Procedural Terminology (CPT) and Healthcare Common Procedure Coding System (HCPCS) codes commonly used for telehealth. These include office visit codes, online digital codes, telephone service codes, and HCPCS codes like G2010 and G2012.
Step 2: Confirm the communication method
Now confirm whether the visit was:
- Audio video
- Audio only
- Store and forward or image review
- Patient portal communication
This is a critical step because not every code works for every type of communication. Medicare generally expects real time interactive technology, but audio only can still be used in certain situations, especially when the patient is in the home and cannot use video or does not agree to use video.
Step 3: Choose the correct place of service
After the service and modality are clear, choose the right telehealth Place of Service.
Use POS 10 when the patient receives telehealth in the home. Use POS 02 when the patient received telehealth somewhere other than the home. This is one of the simplest parts of the claim, but it is also one of the most commonly missed.
Step 4: Add the right modifier only if it applies
Once the service and POS are right, check whether a modifier is needed. For audio-only services, the American Medical Association (AMA) states that modifier 93 is used for synchronous, real-time audio-only telemedicine services, and HHS says Medicare requires 93 and or FQ in certain cases for Federally Qualified Health Centers (FQHCs) and Rural Health Clinics (RHCs).
Some coders still expect modifier 95 on every telehealth claim, but that is not a safe assumption. CMS says modifier 95 is specifically used for certain outpatient therapy telehealth services in hospital settings, while professional telehealth billing focuses on correct POS reporting. That is why coders should always check the payer rule before adding 95 by habit.
Which telehealth CPT codes are commonly used?
There is no single telehealth code that fits every virtual visit. The right code depends on the type of service.
Office and outpatient visit codes
For many live telehealth visits, coders work from regular office and outpatient evaluation and management code families when payer rules allow it. These are often used when the virtual visit functions like a regular medical visit and the documentation supports the level billed. The AMA lists common code families such as 99202 to 99215 among frequently used telehealth CPT codes.
Online digital services
If the communication happened through a patient portal over several days, the code family is different. AMA lists 99421 to 99423 and 98970 to 98972 among common digital communication codes. These are not the same as a live telehealth visit.
Telehealth Virtual Check-ins
CMS says G2012 is used for a brief communication technology-based service, often called a "virtual check-in, for an established patient. The service should not come from a related E and M visit in the previous 7 days, and it should not lead to a visit in the next 24 hours or the soonest available appointment.
Remote evaluation of images or video
CMS says G2010 is for remote evaluation of recorded video or images submitted by an established patient, with follow-up within 24 business hours. This is not the same as a full video appointment.
How should you code telehealth audio-only visits?
Telehealth Audio-Only Visits should never be treated like a shortcut version of a video visit. They have their own rules. AMA says Modifier 93 applies to real-time audio-only medical services that meet the requirements of the code. HHS also says that for Medicare, audio-only use depends on the patient being in the home and the provider being capable of video, while the patient is unable to use video or does not consent to it.
That means the note should clearly show why the encounter was audio only, what service was performed, and whether the patient’s situation met the payer’s rule. If that is not documented, the claim is more likely to be questioned later.
What documentation should support a telehealth claim?
A strong telehealth claim should always match the chart note. At a basic level, the note should show:
- What service was performed
- Whether the visit was audio-video, audio-only, or another allowed format
- Where the patient was located
- Why the service met the requirements of the code
- Any required patient consent for the service
Common Telehealth Coding Mistakes We See
- POS is wrong (02 vs 10) or not supported by documentation.
- Modifier does not match the modality, especially for audio-only visits.
- A check-in is coded like a full visit, or vice versa.
- Notes are too thin, so the payer cannot see the medical decision-making.
