CPT 45915: Removal of Rectal Foreign Body or Fecal Impaction Under Anesthesia

CPT code 45915 designates the surgical removal of a foreign body or fecal impaction from the rectum performed with the patient under anesthesia. Clinically, this code applies when manual or instrument-assisted extraction is required in a controlled anesthetic setting, distinguishing it from bedside or non-anesthetized interventions. Nationally, accurate use of this code affects procedural reporting, facility billing, and capture of resource intensity for rectal obstruction procedures.

Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of clinical context, typical sites of service, and common billing considerations associated with CPT code 45915. The publication summarizes expected use cases, payer coverage patterns, and common modifiers identified for this procedure. It also highlights benchmarking approaches and policy considerations relevant to procedure reporting and facility claims. The content is intended for healthcare billing professionals, practice managers, and policy analysts seeking a focused national perspective on coding and billing for rectal foreign body and fecal impaction removal under anesthesia.

Billing Code Overview

CPT code 45915 describes the surgical removal of a foreign body or fecal impaction from the rectal canal performed with the patient under anesthesia. This procedure involves manual or instrument-assisted extraction of obstructing material from the rectum when less invasive measures are insufficient or contraindicated.

Service type: Surgical removal of rectal foreign body or fecal impaction under anesthesia
Typical site of service: Operating room or other setting where anesthesia is administered (inpatient or outpatient surgical suite)

Clinical & Coding Specifications

Clinical Context

A typical patient is an adult presenting to the emergency department or operating room with a retained rectal foreign body or severe fecal impaction that cannot be safely removed awake. Patients often have acute rectal pain, bleeding, obstipation, or signs of obstruction. After triage and focused history, imaging (abdominal/ pelvic radiographs or CT) is used to localize the object or impaction and assess for perforation. The procedure 45915 is performed with the patient under anesthesia (general or monitored anesthesia care) to provide muscle relaxation and analgesia, enabling safe manual or instrument-assisted removal. Peri-procedural workflow includes informed consent, pre-anesthesia evaluation, anesthesia administration, operative removal of the foreign body or impacted stool, inspection for mucosal injury, possible hemostasis, and post-anesthesia recovery. Disposition ranges from same-day discharge with outpatient follow-up to admission if complications (perforation, ongoing bleeding, or sepsis) are present.

Coding Specifications

Modifier	Description	When to Use
`23`	Unusual anesthesia	Use when a procedure normally done without general anesthesia requires general anesthesia due to patient condition or procedure complexity.
`22`	Increased procedural services	Use when documentation supports substantially greater service than standard for `45915` (extensive dissection, prolonged removal).
`52`	Reduced services	Use when the procedure is partially reduced or not completed as planned.
`53`	Discontinued procedure	Use when procedure is started but terminated due to extenuating circumstances or patient safety concerns.
`59`	Distinct procedural service	Use when another distinct procedure is performed in a separate anatomic site or single encounter that is not normally reported with `45915`.
`62`	Two surgeons	Use when two surgeons work together as primary surgeons performing distinct portions of the procedure.
`76`	Repeat procedure by same physician	Use if the same physician performs a subsequent service later the same day (not in provided list; not selected).
`78`	Unplanned return to OR by same physician following initial procedure for a related procedure during the postoperative period	Use when reoperation is required for complications after `45915`.
`79`	Unrelated procedure or service by the same physician during the postoperative period	Use when an unrelated procedure is performed during global period.
`51`	Multiple procedures	Use when `45915` is billed with other surgical procedures performed at the same session.

Taxonomy Code	Specialty	Notes
207P00000X	Proctology (Colorectal Surgery)	Colorectal surgeons commonly manage complex rectal foreign bodies and fecal impaction requiring anesthesia.
207L00000X	General Surgery	General surgeons often perform rectal foreign body extractions and manage complications.
2080P0003X	Gastroenterology	Gastroenterologists may perform endoscopic-assisted removal or evaluation but typically under sedation; involvement when endoscopic techniques are used.
2086S0121X	Emergency Medicine	Emergency physicians identify, stabilize, and arrange operative removal; may perform bedside attempts if safe.
207RH0000X	Obstetrics & Gynecology	Gynecologic surgeons occasionally involved when proximity to pelvic organs or combined procedures are required.
