Office and Clinic-Based Procedures: What This Category Means for ASC Billing
This category covers 683 CPT codes that are commonly performed in a physician office or clinic, reported under place of service 11, rather than in a certified Ambulatory Surgery Center. These are everyday office services: evaluation and management visits, joint and bursa injections, and image-guided injections that a provider can deliver in the clinic without an operating room. Code 99213, an established patient office visit, is the clearest example, but the group also includes procedures like 20610, drainage or injection of a major joint or bursa without ultrasound.
For an ASC biller, the key point is that these codes generally do not flow through the ASC facility claim. Medicare and most payers expect them in the office setting, where the physician's payment already accounts for the practice's room, staff, and supplies. They are distinct from the surgical procedures on CMS Addendum AA, the ASC Covered Procedures List, and from the covered ancillary services on Addendum BB. When a service belongs in the office, billing it as an ASC facility line usually leads to a denial.
That does not mean these procedures never appear near an ASC. Many ASC-affiliated practices perform injections such as 0213T, a paravertebral injection with ultrasound guidance in the cervical or thoracic spine, or 0232T, a platelet-rich plasma injection, in the clinic on the professional side. The billing question is which setting the service was actually furnished in and which place of service and claim type the payer expects. DataLily's procedure library tracks CPT-specific prior-authorization and documentation requirements so teams can confirm those details before the claim goes out.
Office & Clinic-Based Procedures codes(showing 120 of 683)
Are office and clinic-based procedures paid in an ASC?
Generally no. These codes are expected in the office setting under place of service 11, where the physician's payment accounts for the room, staff, and supplies. They are not the surgical procedures on CMS Addendum AA that Medicare pays in a certified ASC. If a service in this category is furnished in the clinic, it should be billed as an office service rather than as an ASC facility line.
What CPT codes fall into the office and clinic-based category?
This category includes 683 CPT codes commonly performed in a physician office or clinic. They range from evaluation and management visits such as 99213, an established patient office visit, to joint and soft tissue injections like 20610, and image-guided injections such as 0213T and 0232T. The common thread is that a provider can deliver them in the clinic without an operating room.
How should a biller handle a code that is office-based but performed near an ASC?
Start by confirming where the service was actually furnished and which place of service and claim type the payer expects. An office-based injection performed in the clinic is billed on the professional side under place of service 11, not on the ASC facility claim. Check any prior-authorization and documentation requirements for the specific code first, since payer rules vary by procedure.
