About 62331: Percutaneous lumbar ligamentum flavum decompression
Reports percutaneous removal of hypertrophic ligamentum flavum to decompress neural elements at each additional lumbar level treated after the primary level.
This add-on code represents percutaneous decompression for lumbar spinal stenosis associated with hypertrophy of the ligamentum flavum. The physician removes tissue through a percutaneous approach to relieve pressure on neural elements at an additional lumbar level. Interventional pain physicians and spine specialists commonly perform this procedure in an outpatient setting; the operative record should identify the levels treated and describe the decompression performed at each one.
Report 62331 only with the primary-level procedure, 62330, and use it for each additional lumbar level treated. The documentation should distinguish the primary level from the additional level or levels. CMS treats this as an add-on paid within the primary procedure’s global period. The code is already priced as bilateral, so modifier 50 does not increase payment.
