Anesthesiology and Pain Medicine in the ASC
Interventional pain physicians perform a high volume of image-guided spinal and joint procedures, much of which has moved into ambulatory surgery centers. The CPT families that matter most run through the spinal and paravertebral injection range (62320-64999) and the joint injection codes around 20550-20611. For example, 64483 is a transforaminal epidural injection at a lumbar or sacral level, and 64493 is a paravertebral facet joint injection at the same level.
Eligibility for the ASC setting depends on each code's ASC-eligibility status. Some codes are ASC-eligible and can be performed in a certified ambulatory surgery center, while others are typically done in a hospital outpatient department or office instead. Because pain procedures often carry prior-authorization and documentation requirements that vary by payer, DataLily AI's procedure library tracks the CPT-specific prior-authorization and documentation requirements for these codes.

Are pain management procedures performed in an ambulatory surgery center?
Yes. Many interventional pain procedures, including epidural steroid injections, facet joint injections, and radiofrequency ablation, are commonly scheduled in ASCs. Whether a specific code suits the ASC setting depends on its ASC-eligibility status, worth confirming before scheduling.
What CPT codes does interventional pain medicine use?
Most fall in the spinal and paravertebral injection range 62320-64999, along with soft tissue and joint injection codes around 20550-20611. Examples include 64483 for a lumbar or sacral transforaminal epidural injection, 62323 for an interlaminar lumbar or sacral epidural injection, 64493 for a lumbar or sacral facet joint injection, and 64635 for radiofrequency destruction of a lumbar or sacral facet joint nerve.
What place of service is used for pain injections in an ASC versus a clinic?
Procedures performed in an ambulatory surgery center are generally billed with place of service 24, while procedures performed in an office-based or clinic procedure suite use place of service 11. The setting affects how the service is paid, so confirm the correct place of service and the code's coverage status before billing.
