What G0571 covers
The surgeon applies a cryoprobe to a nerve during an operation to interrupt pain signaling. A recognized example is treatment of intercostal nerves during minimally invasive repair of pectus excavatum. The service is performed in the operating room as part of the surgical procedure, rather than as a separate clinic-based nerve treatment.
Report G0571 only with a primary procedure. The operative report should identify the nerve treated, document use of cryoablation during the operation, and support the associated primary procedure. CMS classifies this as an add-on code, with payment made within the primary procedure’s global period. It is not reported as a standalone service outside that surgical episode.

G0571 billing questions
Can G0571 be billed by itself?
No. CMS identifies it as an add-on code that must be reported with a primary procedure.
What should the operative report document?
Document the nerve treated, the intraoperative use of a cryoprobe, and the primary procedure performed.
Is it appropriate for intercostal nerve cryoablation during pectus repair?
It may describe intraoperative cryoablation of intercostal nerves during minimally invasive pectus excavatum repair. The record must support that the nerve treatment was performed during the operation.
How does the primary procedure affect payment?
CMS places payment for G0571 within the primary procedure’s global period. Report it with the primary procedure rather than as a separate standalone service.
Is G0571 the same as chemical destruction of a peripheral nerve?
No. G0571 identifies intraoperative cryoablation; code 64640 describes destruction of a peripheral nerve or branch using a neurolytic agent.
