What 64582 covers
A surgeon implants a stimulation lead at the hypoglossal nerve, a respiratory sensing lead, and a pulse generator, generally during an operating-room procedure for a patient selected for hypoglossal nerve stimulation to treat obstructive sleep apnea. System testing and programming performed during implantation, and imaging guidance when used, are part of the service. Otolaryngologists and surgeons specializing in sleep-disordered breathing commonly perform the operation.
Report this code for the initial open implantation of the system, not for later revision, replacement, or removal. The operative report should identify the implanted components and document the procedure performed. CMS assigns a 90-day global period, which includes the day-before preoperative visit and 90 days of related postoperative care. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and the others at 50%. CMS pays a bilateral procedure reported with modifier 50 at 150%. Assistant-at-surgery payment requires documented medical necessity; co-surgeons and team surgery are not permitted.

- 64584Stimulator removalHypoglossal array and generator
- 64584 describes removal of an existing hypoglossal nerve stimulation system; it is not the initial implantation code.
- 64568Nerve stimulatorElectrode array and pulse generator

64582 billing questions
How does this differ from code 64583?
64582 describes the initial open implantation. Code 64583 is for revision or replacement of the hypoglossal nerve stimulation system.
Is the pulse generator separately reported?
The initial implantation service includes the pulse generator along with the nerve stimulation system. Do not separately report a generator implantation code for that same system placement.
What documentation supports the initial implantation?
The operative report should show that the hypoglossal nerve stimulation system was implanted and identify the components placed. It should distinguish initial implantation from revision, replacement, or removal.
What postoperative care is included?
CMS assigns a 90-day global period. It includes the day-before preoperative visit and 90 days of related postoperative care.
Can an assistant surgeon be reported?
CMS allows assistant-at-surgery payment only when medical necessity is documented. Co-surgeons and team surgery are not permitted for this code.
Where these rates come from
FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
