What 47564 covers
A surgeon uses a laparoscope to remove the gallbladder and also explores the common bile duct during the operation. Exploration may be performed when duct stones are suspected or identified, such as in a patient with biliary obstruction or choledocholithiasis. This procedure is generally performed in a hospital operating room by a general surgeon or another surgeon qualified to perform biliary surgery.
Select this code when the operative report supports both laparoscopic gallbladder removal and common duct exploration; gallbladder removal alone or removal with cholangiography alone points to a different code. Document the findings and the exploration performed, including any duct-stone management. Medicare assigns a 90-day global period, including the day-before preoperative visit and related postoperative care for 90 days. 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. An assistant at surgery may be paid; co-surgeon payment requires supporting documentation, and team surgery is not permitted.

47564 billing questions
How is this different from 47562?
47562 covers laparoscopic gallbladder removal without common duct exploration. Use 47564 when the operative record documents duct exploration as part of the operation.
How is this different from 47563?
47563 identifies laparoscopic gallbladder removal with cholangiography. Choose 47564 when the documented service includes common duct exploration; do not select it solely because imaging was performed.
Can the assistant surgeon be reported?
CMS permits payment for an assistant at surgery for this procedure. Co-surgeon payment requires supporting documentation.
Should modifier 50 be appended?
No. CMS identifies bilateral adjustment as inappropriate for this code because of its descriptor or anatomy.
What postoperative care is included?
The 90-day global period includes the day-before preoperative visit and related postoperative care for 90 days. Unrelated services are not described by that global-care rule.
How are other procedures in the same session paid?
The highest-valued procedure is paid in full, and other procedures performed in that session are subject to the standard multiple-procedure reduction.

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.
