Medicare allowed amount for participating (non-QP) physicians, before deductible, coinsurance and claim adjustments. Not a patient’s bill or a hospital charge.

What 47579 covers

This unlisted code identifies laparoscopic surgery on the biliary tract that is not represented by a more specific CPT procedure code. A surgeon reports it for operative work performed through laparoscopic access when the documented service does not match a defined biliary procedure. It is not the code for a routine laparoscopic gallbladder removal, with or without cholangiography, or with common bile duct exploration; those procedures have specific codes.

Medicare assigns this CPT Category I code physician fee schedule status C, or carrier priced. CMS publishes no national payment, and the Medicare Administrative Contractor sets payment for each claim. The contractor also sets the global period. Standard multiple-procedure reduction applies when qualifying procedures are performed in the same session. The operative report should clearly describe the laparoscopic technique, biliary anatomy treated, and work performed so the contractor can assess the unlisted service.
