8. CPT codes 64400-64530 describe injection of anesthetic agent for diagnostic or therapeutic purposes, the codes being distinguished from one another by the named nerve and whether a single or continuous infusion by catheter is utilized. All injections into the nerve including branches described (named) by the code descriptor at a single patient encounter constitute a single unit of service(UOS). For example:
(1) If a physician injects an anesthetic agent into multiple areas around the sciatic nerve at a single patient encounter, only one UOS of CPT code 64445 (injection, anesthetic agent; sciatic nerve, single) may be reported.
(2) If a physician injects the superior medial and lateral branches and inferior medial branches of the left genicular nerve, only one UOS of CPT code 64450 (Injection, anesthetic agent; other peripheral nerve or branch) may be reported regardless of the number of injections needed to block this nerve and its branches.
