Practices lose thousands every year not because of bad care, but because of one wrong code on a telehealth claim. The CMS telehealth billing guidelines for 2026 are specific, and Medicare does not pay out on guesswork.
The telehealth place of service code you enter tells CMS the entire story of that encounter. You can clear all delayed and denied funds if done correctly. However, one mistake can risk delays, denials, and even a backlog of unexpected work that disrupts the workflow.
Your Telehealth Claims Are Getting Rejected for a Reason
Denials in telehealth are rarely arbitrary. Once you know where to look, the pattern becomes clear and there is nearly always a definite, correctable explanation.
It Starts With the Wrong POS Code
Place of service codes are not just administrative formality. CMS uses them to determine:
- If the telehealth service is reimbursable at all
- Which fee schedule applies to that claim
- Whether the patient location matches the billed service type
Many procedures continue to use out-of-date codes by default or confuse which code is appropriate for a certain situation. It only takes one error to start a denial.
What CMS Needs to See Before It Pays Out
Before a telehealth claim gets approved, CMS checks a few non-negotiables:
- The provider needs to be a Medicare telehealth provider with eligibility.
- The service needs to be listed among the telehealth services that Medicare has approved.
- The visit must use a real-time audio-visual platform
- Audio-only visits carry separate conditions and do not automatically qualify
The documentation, which should show what type of modality was utilized and where the patient was at the time of the visit, needs to clearly indicate that the service was furnished as claimed according to the CMS MLN guidelines.
Telehealth POS Codes Cannot Be Interchanged
Applying an incorrect telehealth POS code can no longer be considered a mistake by the time we reach 2026. It makes a direct impact on your payment and its amount.
The Difference between POS 02 and POS 10
The majority of billing mistakes start here. The simple breakdown is as follows:
- POS 02 is applicable when the patient is in an institution, clinic, or any other place other than their home.
- POS 10 applies when the patient is at home during the telehealth visit
A patient sitting in their living room during a video visit should have POS 10 on that claim, not POS 02. Plenty of claims still come through with POS 02 simply because the billing team never updated the default in their system after CMS introduced POS 10.
POS 11 and POS 12: Where Practices Get Tripped Up
- POS 11 describes the provider’s office location, not the patient’s
- POS 12 refers to the patient’s home in a non-telehealth, in-person context
Attaching POS 12 to a telehealth claim is a mismatch that raises flags immediately. The confusion usually comes from teams billing both in-person and remote services and applying codes out of habit.
| POS Code | What It Means | When to Use It | Common Mistake |
| POS 02 | Telehealth, patient not at home | Patient at a clinic or facility | Using it for home-based visits |
| POS 10 | Telehealth, patient at home | Patient at home during visit | Not switching from POS 02 after policy update |
| POS 11 | Provider’s office | Describes provider location only | Misapplying it as a patient location code |
| POS 12 | Patient’s home, non-telehealth | In-person home visits only | Attaching it to remote telehealth claims |
What CMS Actually Expects From Your Billing in 2026
Knowing the right codes is half the job. The other half is making sure your documentation holds up if CMS takes a closer look.
Documentation Mistakes That Put Your Claim at Risk
One of the most common mistakes is submit incomplete notes. Following are the record factors that can make your document weak.
- Make sure to specify the technology and devices used in the process
- Patient’s location during the visit should be stated
- Reflect the same clinical detail expected from an in-person encounter
Templated notes that read identically for in-office and telehealth visits are a red flag in any audit. CMS documentation requirements for telehealth in 2026 expect the telehealth-specific elements to be clearly present every time.
Medicare Telehealth in 2026: What Carried Over and What Shifted
Some of the flexibilities from the public health emergency have been pushed out through 2026, including, :
- Patients receiving telehealth from home without geographic restrictions
- Certain telehealth services can be expanded for provider eligibility
There have been increased requirements in some specialties when it comes to documentation and supervision. According to the 2026 Medicare Physician Fee Schedule, the billing departments need to verify that all of the services that they are billing fall within the approved list for this year. Flows from 2022 which have not been reviewed are most likely based on outdated assumptions.
Getting It Right Is Cheaper Than Getting It Wrong
One incorrect POS code on a frequently used service leads to the same error being replicated on many bills until it is discovered. By that time, the inefficiency and risk of non-compliance would outweigh any savings from the initial claim.
The CMS guidelines for telehealth billing in 2026 were never intended to be a trap. Practices that build their billing workflows around current CMS requirements spend less time chasing payments and more time focused on care, and that is a straightforward return on getting the basics right.
If your telehealth claims are coming back denied or your team is buried in resubmissions, the issue is almost always upstream. Delaware Medical Billing helps practices align their telehealth billing with current CMS guidelines so claims go out right the first time. Reach out to see where your current workflow stands.
