Place of Service (POS) codes are vital to any medical billing process. The POS code is the location where a health professional performs the services, which significantly affects how claims are adjudicated and paid by payers. One of the most frequently used, yet widely misunderstood codes is POS 11.
POS 11 is integral to physician practices and simplifies the credentialing process, thus decreasing claim denials, enhancing their revenue cycle management (RCM). When you use this code correctly, it helps to prevent costly delays for non-compliance and ensure maximum reimbursements are received for services provided in the office.
1) What is POS 11?
POS 11 is defined as follows by the Centers for Medicare & Medicaid Services (CMS):
“Office – Location, other than a hospital’s or patients home; where a health professional provides medical or short-term therapy services (does not include the place where the provider simply scribbles on clipboard.)
Put another way, POS 11 is a doctor’s office — this is a fixed site owned, leased or rented by the physician or practice where patients go to receive care.
Example:
A cardiologist conducting visits in private clinics to see patients for check-ups, ECGs and through follow-up would apply POS 11 for those services.
2) When to Utilize POS-11 in Medical Billing
“Knowing when and how to use POS 11 is critical for compliance” and getting optimum remuneration:
Correct Scenarios:
- Follow-up Care Regular office visits
- Chronic condition management
- Subacute, noncatastrophic in-office procedures (era joint injections and wound care)
- Preventative Services like annual wellness visit
Avoid POS 11 If:
- Services are provided in the outpatient hospital setting (POS 22)
- The facility is hospital owned clinic.
- The care is provided with a facility that is not owned or operated by the physician.
Key Compliance Tip:
If the practice is hospital based, but still bills under POS 11, it should ensure that it complies with CMS requirements establishing that the facility is independent.
3) POS-11 Reimbursement Rules
There are many reasons why POS 11 is important, but one of them is payment variance:
Higher Reimbursement:
Services provided in the office and billed with POS 11 are generally reimbursed at higher rates than when performed in an outpatient hospital (POS 22). That’s because hospitals collect a “facility fee,” while office companies only get the physician fee.
Payer-Specific Variations:
Some health insurance companies may have exceptions to their POS requirement or payment reduction. Be sure to check payer policies so you’re not underpaid or denied.

POS 11 – Office |
POS 22 – Outpatient Hospital |
Location |
Private physician office | Hospital outpatient clinic |
Ownership |
Physician or group-owned | Hospital-owned or operated |
Reimbursement | Higher physician fee schedule |
Lower physician payment + facility fee |
Common Use Case | Primary care visits, minor procedures |

Impact on RCM:
Billing POS 22 when POS 11 is more appropriate can result in underpayments and beware— potential payer audits and compliance exposure.
5) ICD 11 Coding Accuracy Tips
So you don’t face any denials and get smooth processing:
Match CPT/HCPCS Codes:
Verify the selected procedure codes are characteristic of an office location. Some procedures mandate particular modifiers when performed outside a facility.
Use Clear Documentation:
Clearly note patient encounters, including location specifics and physician ownership of the space.
Verify Before Submission:

6) POS 11—Credentialing and Eligibility Verification
So exactly how much is your billing directly impacted by the effectiveness of credentialing:
Eligibility Checks:
Verify patient’s insurance and office visit benefits PRIOR to scheduling or rendering of services.
Credentialing Compliance:
Office-based services: Providers need to be appropriately credentialed with each payer. POS misuse can result in network mismatch rejections.
Best Practice:
Add eligibility verification tools to your RCM system to lower your claim rejection rate.
