What 44950 covers
This code describes open removal of the appendix, commonly performed by a general surgeon in a hospital operating room for acute appendicitis. The surgeon reaches the appendix through an abdominal incision rather than using a laparoscopic approach. Emergency cases often follow evaluation for right lower quadrant pain and imaging or examination findings consistent with appendicitis.
Select the code based on the operative approach and documented disease findings. The operative report should support removal of the appendix by open approach; rupture with an abscess or generalized peritonitis points to 44960, while laparoscopic removal points to 44970. The 90-day global includes the day-before preoperative visit and 90 days of related postoperative care. When multiple procedures occur in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. Do not append modifier 50 for this single-organ operation. Assistant-at-surgery payment may be made; co-surgeon payment requires supporting documentation, and team-surgery payment is not permitted.

44950 billing questions
How does 44950 differ from 44960?

When should 44970 be reported instead?
Report 44970 when the appendix is removed laparoscopically. Code 44950 describes the open approach.
Is 44955 an add-on to 44950?
44955 describes appendectomy performed for an indicated purpose during another major procedure and is reported in addition to that primary procedure. It is not an add-on to 44950.
What documentation supports 44950?
The operative report should establish that the appendix was removed through an open approach and describe the relevant operative findings. Document rupture, abscess, or generalized peritonitis when present to support code selection.
Can modifier 50 be used for 44950?
No. The appendix is a single organ, so modifier 50 is not appropriate.
How is related postoperative care handled?
The 90-day global includes the day-before preoperative visit and 90 days of related postoperative care.
