CPT Code Overview
CPT code 44950 represents an appendectomy, a surgical procedure to remove the appendix. This code is classified under general surgery and is most commonly performed in an inpatient hospital setting (Place of Service 21). The appendectomy is a critical intervention for patients presenting with acute appendicitis or related conditions, and is a standard procedure in emergency surgical care.
Clinical & Coding Specifications
Clinical Context
A typical patient scenario involves an adult presenting to the emergency department with acute abdominal pain, localized to the right lower quadrant. Physical examination and imaging studies suggest acute appendicitis. The patient is admitted to the inpatient hospital (Place of Service 21) and evaluated by a general surgeon. After confirmation of diagnosis, the patient undergoes an appendectomy, coded as 44950. Postoperative care is provided, and the patient is monitored for complications such as infection or abscess formation before discharge.

-
K35.80– Acute appendicitis without perforation or gangrene- Represents the most common indication for appendectomy, where the appendix is inflamed but not ruptured.
-
K35.2– Acute appendicitis with generalized peritonitis- Indicates a more severe case where infection has spread, often requiring urgent surgery.
-
K36– Other appendicitis- Covers less typical presentations or chronic forms, which may still necessitate appendectomy.
-
K37– Unspecified appendicitis- Used when the clinical diagnosis is appendicitis but specifics are not documented.
-
K38.1– Appendicular abscess- Indicates a localized abscess related to the appendix, which may require surgical intervention such as appendectomy.
Related CPT Codes
-
44955– Appendectomy; when done for indicated purpose at time of other major procedure (not as separate procedure)- Used when an appendectomy is performed during another major surgery, not as a standalone procedure.
-
44960– Appendectomy; for ruptured appendix with abscess or generalized peritonitis- Used when the appendix has ruptured and there is abscess or peritonitis, indicating a more complex procedure.
-
49000– Exploratory laparotomy, exploratory celiotomy with or without biopsy(s) (separate procedure)- May be performed when diagnosis is unclear or additional exploration is needed; sometimes used in conjunction with appendectomy.
-
44180– Laparoscopy, surgical, enterolysis (freeing of intestinal adhesion) (separate procedure)- Used if adhesions are present and need to be freed during the surgical session, possibly alongside appendectomy.
-
44120– Enterectomy, resection of small intestine; single resection and anastomosis- Performed if small bowel resection is required, which may occur in complicated cases involving the appendix.
These codes may be used together in complex surgical cases or as alternatives depending on intraoperative findings.
