A telehealth claim's place of service (POS) code carries more weight than most billing templates treat it. The two-digit code decides which of two Medicare Physician Fee Schedule rates the claim is paid at. POS 02 marks a patient outside their home and pays the lower facility rate; POS 10 marks a patient at home and pays the higher non-facility rate. A biller who defaults to the wrong code, out of habit or confusion about the 2024 change, creates a payment the visit note itself may not support, and that gap is exactly what claims-data audits are built to find.
POS 02 and POS 10: What Each Code Identifies
CMS created POS 02 in 2017 to mark a Medicare telehealth service generally. Effective January 1, 2024, CMS added POS 10 and required distant-site practitioners to choose between the two on every professional telehealth claim. Under the CMS Place of Service Code Set, POS 02 covers a patient located somewhere other than home when receiving the service, and POS 10 covers a patient located in their home, defined broadly enough to include a private residence, an apartment, or temporary lodging such as a hotel room. POS 11, the office code used for in-person visits, is a different category entirely: CMS's telehealth billing instructions treat POS 02 and POS 10 as the only two valid location codes for a Medicare telehealth professional claim.
The Facility Versus Non-Facility Payment Difference
Most codes on the Medicare Physician Fee Schedule carry two payment rates. The non-facility rate assumes the billing practitioner absorbs the overhead of the visit; the facility rate assumes a hospital, skilled nursing facility, or other institution bills separately for that overhead, so it pays less. POS 10 draws the non-facility rate, and POS 02 draws the facility rate. Because the 2024 rule ties the payment rate to the location code rather than to the CPT code alone, the same telehealth visit for the same patient can be reimbursed at two different Medicare rates depending only on which of the two boxes the biller checks.
The place of service code states where the patient was, not where the practitioner sat, and that detail alone decides which of two Medicare rates the claim is paid at.
How Auditors Identify a Place of Service Mismatch
Program integrity contractors find place-of-service errors by matching one claims data source against another, a method the HHS Office of Inspector General (OIG) has used for years outside telehealth. A 2015 OIG audit found Medicare contractors had potentially overpaid physicians about $33 million on claims billed at the non-facility rate from January 2010 through September 2012, when roughly three-quarters of those claims were actually delivered in a hospital outpatient setting. A later audit of 2019 and 2020 claims found $22.5 million in overpayments on the same pattern. For telehealth, a 2018 OIG review, before POS 10 existed, compared distant-site telehealth claims against the separate facility-fee claims required at the time and found more than half of a 191,118-claim set, worth $13.8 million, had no matching record. That same cross-referencing now applies directly to POS 02 and POS 10.
What a Mismatch Can Trigger
A single miscoded claim usually draws a denial or a request for records. A pattern across many claims draws more. A Medicare Administrative Contractor or Unified Program Integrity Contractor (UPIC) that finds repeated POS mismatches can demand a recoupment of the rate difference across the sample, and where the sample supports it, extrapolate that demand across the full lookback period. Medicare's overpayment rule requires a provider to report and return an identified overpayment within 60 days, so a mismatch a practice finds on its own carries its own deadline. Where a payer or contractor concludes the pattern reflects deliberate upcoding, the exposure can extend to a False Claims Act referral.

Why Early Legal Counsel Is Critical
It is critical that telehealth providers retain experienced healthcare defense counsel promptly upon receiving a payer audit notice, a records request, or a recoupment demand tied to place-of-service coding. Early legal intervention can protect the provider's rights, ensure an accurate response to the payer's request, avoid inadvertent admissions in a written reply, and preserve defenses before a sampled finding becomes an extrapolated demand. Delaying legal representation can significantly affect the outcome of the audit and expose the practice to unnecessary risk.
