POS 49: Independent Clinic
POS 49 is the place of service code for an independent clinic: a freestanding location, not part of a hospital and not a physician office, providing preventive, diagnostic, therapeutic, or rehabilitative services on an ambulatory basis. It pays the Medicare non-facility rate, the same structure as POS 11.

What does POS 49 mean?
POS 49 identifies an independent clinic: per CMS, a location not part of a hospital and not described by any other place-of-service code, organized and operated to provide preventive, diagnostic, therapeutic, rehabilitative, or palliative services to outpatients only.
It is deliberately a residual category: freestanding, ambulatory, and not something more specific. Before settling on 49, rule out the specific codes: POS 11 (office), POS 20 (urgent care), POS 50 (FQHC), POS 72 (RHC), POS 53 (community mental health center). The full decision table is in our Place of Service reference.
When do you use POS 49?
Use POS 49 when the service location is a freestanding clinic entity rather than a physician's private office, and no dedicated POS code fits:
- Non-hospital addiction medicine or MAT clinics without OTP designation.
- Student health and employer-sponsored clinics.
- Freestanding multi-service clinics owned by a corporate entity where providers rotate.
- Certain therapy and counseling clinics that are not enrolled as offices.
The practical tiebreaker with POS 11 is how the site is enrolled and contracted. If the payer credentialed the location as a clinic entity, mirror that with POS 49; if providers are individually credentialed at a practice office, POS 11. Mismatches between POS and the payer's site file cause pends, not because either code is wrong in the abstract, but because they disagree with enrollment.
How does POS 49 affect payment?
POS 49 pays the Medicare non-facility rate: full practice expense, no separate facility fee, identical pricing structure to an office visit. Switching a claim between POS 11 and POS 49 does not change Medicare dollars, which is why this code flies under the radar until a payer's site-verification edit catches an inconsistency.
Commercial behavior varies more. Some plans load clinic locations with different fee schedules or lower E/M tiers than physician offices, and a few Medicaid programs pay clinic entities per-visit rates. Compare your contracted clinic rates against the Medicare non-facility benchmark with the Medicare fee calculator, and if a plan pays your clinic entity below your physicians' office rates for identical CPT codes, put it on the renegotiation list.
What are the common POS 49 errors and denials?
- Enrollment mismatch pends: claims with POS 49 from a location the payer has on file as an office (or vice versa) get suspended for verification. Fix the provider file, then rebill.
- FQHC/RHC misrouting: designated centers billing POS 49 lose their PPS or all-inclusive rate; that is a self-inflicted underpayment.
- CARC 5: facility-only codes (inpatient E/M, ED codes) with POS 49; interpret remits with the denial code lookup.
- Telehealth defaults: virtual visits from clinic-employed providers going out as POS 49 instead of POS 02/10.
Frequently asked questions
POS 11 is a physician office where practitioners routinely see their own patients. POS 49 is a freestanding clinic that is not organized as a physician office: think multi-service community clinics, student health centers, or corporate-owned treatment clinics staffed by rotating providers. Medicare pays both at the non-facility rate, so the choice rarely changes dollars; it changes how payers profile and credential the site.
No. Federally Qualified Health Centers have their own code, POS 50, and rural health clinics use POS 72, each tied to distinct payment systems. POS 49 is for independent clinics that do not hold FQHC or RHC designation. Billing POS 49 from a designated FQHC misroutes the claim away from the PPS rate the center is entitled to.
Non-facility. POS 49 is not on the CMS list of facility-rate settings, so Physician Fee Schedule services price with full practice expense, the same as an office. The clinic is expected to bear its own overhead with no separate facility fee, which is exactly the economic profile of a freestanding site.
Common users include addiction treatment clinics not attached to hospitals, community mental health operations that are not CMHCs (POS 53), student and employee health clinics, and some multi-specialty clinic corporations where the entity, not individual physicians, holds the payer contracts. If your enrollment describes the site as a clinic rather than a private practice office, POS 49 usually matches the payer's file.
