What 44955 covers
This add-on describes removal of the appendix when it is clinically indicated during another major operation. For example, the surgeon may identify an appendix that requires treatment while operating for a separate abdominal condition. The surgeon performing the operation reports the appendectomy in addition to the code for the primary procedure; 44955 does not describe a standalone appendectomy.
The operative report should identify the primary operation, the appendectomy, and the clinical reason the appendix was removed. Report the code only when the circumstances support an indicated appendectomy during another major procedure, not simply because the appendix was encountered. CMS treats 44955 as an add-on: it is reported with a primary procedure and paid within that procedure's global period. The record should make clear that the appendectomy was performed during the same operative episode as the primary service.
This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

44955 billing questions
When should 44955 be chosen instead of 44950?
Use 44955 when appendectomy is clinically indicated during another major procedure. Use 44950 when appendectomy is reported as the principal operation.
What primary code should accompany 44955?
Report the code for the other major procedure performed during the same operative episode. The operative report should support both the primary operation and the indicated appendectomy.
Can 44955 be billed by itself?
No. It is an add-on code and must be reported with the primary procedure; CMS pays it within that procedure's global period.
What documentation supports reporting 44955?
Document the primary operation, removal of the appendix, and the clinical reason appendectomy was indicated during that operation.
Is 44955 appropriate for a ruptured appendix with generalized peritonitis?
The clinical circumstances and whether appendectomy is performed as the principal operation determine code selection. Code 44960 describes appendectomy for a ruptured appendix with abscess or generalized peritonitis.
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.
