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

What 47620 covers

This open operation removes the gallbladder, explores the common bile duct, and creates a connection between the bile duct and intestine to provide drainage. General or hepatobiliary surgeons may perform it for complex biliary disease, such as duct obstruction or a stricture requiring a bypass, in a hospital operating room. The operative report should establish that all three parts of the procedure were performed; gallbladder removal or duct exploration alone does not describe this service.

Report the combined procedure when the documented work includes cholecystectomy, common duct exploration, and choledochoenterostomy. The 90-day global period includes the day-before preoperative visit and related postoperative care during the 90 days after surgery. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. Modifier 50 is inappropriate. Assistant-at-surgery payment may be available; co-surgeon payment requires supporting documentation, and team surgery is not permitted.

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.
