About 33277: Additional phrenic stimulator lead insertion
Reports each additional transvenous lead placed during phrenic nerve stimulator implantation, beyond the lead service included in the primary system procedure.
This add-on reports placement of an additional transvenous lead for a phrenic nerve stimulation system. These systems stimulate the phrenic nerve to support breathing in patients with central sleep apnea. An electrophysiologist or other physician experienced in cardiac device implantation typically places the lead through venous access, using imaging guidance as needed, in a hospital or other procedural setting. The code distinguishes the additional lead work from the primary system implantation.
Report 33277 only with the primary phrenic nerve stimulator system insertion code, 33276, when an additional lead is placed. Documentation should identify the implanted system, the number of leads placed, and the additional lead work supporting this add-on. CMS classifies 33277 as an add-on code paid within the primary procedure’s global period. It is not a stand-alone report for an initial system insertion.
