Summary & Overview
CPT 0736T: Rectal Catheter Insertion with Colonic Lavage
CPT code 0736T denotes insertion of a rectal catheter with colonic lavage using water to induce defecation. The code captures a targeted therapeutic procedure used for bowel evacuation and fecal management when conservative measures are inadequate. Nationally, clarity on coding and coverage for this procedure affects billing consistency, facility workflow, and access for patients who require procedural bowel care.
Key payers in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of clinical context, common sites of service, and the role of this procedure in bowel management. The publication presents benchmarks where available, summarizes relevant policy and coverage considerations, and explains coding implications for procedural and facility billing.
This summary is intended for clinicians, billing professionals, and policy analysts seeking to understand the clinical purpose of 0736T, common service settings, and the payer landscape that shapes reimbursement and utilization practices. Data not available in the input is noted where applicable.
Billing Code Overview
CPT code 0736T describes insertion of a rectal catheter and performance of colonic lavage (washing out the colon with water) to induce defecation. This procedure involves introducing a catheter into the rectum and administering fluid to stimulate evacuation.
-
Service type: Therapeutic colonic lavage
-
Typical site of service: Outpatient or inpatient procedural setting where bowel management or fecal disimpaction procedures are performed, such as hospital procedure areas, gastroenterology clinics, or skilled nursing facilities providing bowel care.
Clinical & Coding Specifications
Clinical Context
A typical patient is an adult presenting to an outpatient endoscopy unit or ambulatory surgical center with acute constipation or fecal impaction unresponsive to oral laxatives and enemas. The provider performs a rectal catheter insertion and colonic lavage with water to induce defecation when manual disimpaction is incomplete or contraindicated. Pre-procedural assessment includes focused history (bowel habits, prior surgeries, anticoagulant use), vital signs, and review of contraindications (suspected bowel perforation, severe hemodynamic instability). The procedure is performed with the patient in lateral decubitus or Sims position, using aseptic technique; water lavage is administered via a rectal catheter until stool evacuation is achieved or the procedure is terminated for intolerance or clinical reasons. Post-procedure monitoring includes assessment of vital signs, return of bowel function, and documentation of volume instilled, patient tolerance, and any complications such as cramping or rectal mucosal trauma. Typical site of service is an ambulatory surgical center, endoscopy suite, emergency department, or inpatient bedside (floor or ICU) depending on acuity and patient stability. Service type: Procedural therapeutic irrigation/cleansing of the colon via rectal catheterization.
Coding Specifications
| Modifier | Description | When to Use |
|---|---|---|
22 | Increased procedural services | Use when work required is substantially greater than typical for the procedure (e.g., technically difficult lavage due to severe fecal impaction). |
51 | Multiple procedures | Use when billing multiple distinct procedures during the same session per payer rules. |
52 | Reduced services | Use when the procedure is partially reduced or not completed as originally intended. |
53 | Discontinued procedure | Use when the procedure is started but terminated due to patient instability or emergent change. |
54 | Surgical care only | Use when the provider bills only the surgical portion and another provider bills pre/post op care. |
55 | Postoperative management only | Use when provider bills only postoperative care following the procedure. |
56 | Preoperative management only | Use when provider bills only preoperative work unrelated to procedural billing by another clinician. |
62 | Two surgeons | Use when two surgeons with distinct roles perform the procedure due to complexity. |
66 | Surgical team | Use when a surgical team performs services per payer policies. |
78 | Unplanned return to OR after initial procedure | Use if a return to the operating room is required for complications related to the lavage. |
80 | Assistant surgeon | Use when an assistant surgeon performs a portion of the procedure. |
81 | Minimum assistant surgeon | Use when minimal assistance is provided. |
82 | Assistant surgeon (when qualified resident not available) | Use when a non-resident assistant is required and no qualified resident is available. |
AS | Physician assistant, nurse practitioner, or clinical nurse specialist services when performed as primary surgeon | Use when an advanced practice provider legally performs the procedure per state law and payer rules. |
TG | Service performed by a resident without an attending present (GME) | Use when a resident performs the service without the direct presence of an attending, per payer policy. |

| 207LH0000X | Gastroenterology | Gastroenterologists perform therapeutic rectal procedures and manage bowel clearance in endoscopy suites. |
| 207K00000X | General Surgery | General surgeons may perform bedside colonic lavage in inpatient or emergency contexts. |
| 367A00000X | Family Medicine | Family physicians may perform lavage in outpatient or urgent care settings when within scope. |
| 363L00000X | Emergency Medicine | Emergency physicians perform urgent lavage for acute fecal impaction in the ED or inpatient setting. |
