Surgical Nurse Practitioners in the ASC: How the Role Bills
A surgical nurse practitioner supports the operating surgeon rather than owning the case, so the NP has no CPT family of their own. Instead, they bill alongside the surgeon's procedure codes, most often as a surgical assistant. The claim usually carries the surgeon's primary procedure code with the assistant-at-surgery modifier -AS appended.
Whether an assistant is reportable depends on the specific surgical code and payer rules, not on the NP's specialty, so documentation and code-level checks matter. DataLily's procedure library tracks CPT-specific prior-authorization and documentation requirements, which helps an ASC confirm assistant-at-surgery eligibility before the claim goes out.
This role bills around the surgical case rather than carrying its own ASC-payable procedure codes. See the surgical specialty hubs for the procedures performed in the ASC.
Do nurse practitioners work in ambulatory surgery centers?
Yes. Surgical nurse practitioners are part of many ASC care teams in a peri-operative, billing-adjacent role. They help manage the patient before and after surgery and frequently assist the operating surgeon during the procedure, with the place of service reported as 24.
What CPT codes does a surgical nurse practitioner bill?
There is no dedicated CPT family for a surgical NP. When the NP assists at an operation, the claim carries the surgeon's primary procedure code with the assistant-at-surgery modifier -AS appended. The underlying procedure code, and whether it sits on the ASC Covered Procedures List, follows the surgeon's work, not the NP's role.
Can a nurse practitioner bill as an assistant at surgery in an ASC?
Often, but it depends on the specific procedure code and the payer. Many surgical codes allow an assistant at surgery and are reported with modifier -AS, while others do not permit one. Because eligibility is code-specific, confirm the assistant-at-surgery rule and documentation for each CPT code before submitting the claim.
