Summary & Overview
CPT 44407: Stoma Colonoscopy with EUS-Guided Aspiration/Biopsy
CPT code 44407 represents a stoma-access colonoscopy combined with endoscopic ultrasound (EUS) and intramural or transmural aspiration or biopsy of the large intestine (sigmoid, descending, transverse, ascending colon, and cecum). This procedure is clinically significant for patients with ostomies or other stomas who require diagnostic evaluation, tissue sampling, or therapeutic aspiration of lesions adjacent to the colon. Nationally, accurate coding for complex endoscopic procedures like 44407 affects coverage determination, utilization tracking, and quality measurement across payers.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of the clinical and billing context for 44407, typical sites of service, common modifiers used with endoscopic procedures, and the types of benchmarks and policy updates that influence reimbursement and prior authorization practices. The publication also outlines what to expect in claims processing and documentation requirements for EUS-guided aspiration or biopsy via a stoma. Data not available in the input regarding associated taxonomies, specific ICD-10 diagnoses, related codes, and payer-specific coverage policies is noted where applicable.
Billing Code Overview
CPT code 44407 describes a colonoscopy performed through a stoma (an artificial opening in the skin). The procedure includes endoscopic ultrasound (EUS) examination with intramural or transmural aspiration or biopsy of the large intestine, limited to the sigmoid, descending, transverse, or ascending colon and cecum, and nearby structures.
-
Service type: Endoscopic diagnostic and interventional procedure with EUS-guided aspiration or biopsy
-
Typical site of service: Hospital outpatient department or ambulatory surgical center where stoma-access colonoscopy and EUS can be performed
Clinical & Coding Specifications
Clinical Context
A 62-year-old patient with a permanent colostomy following prior colorectal surgery presents with new onset abdominal pain, altered stoma output, and a palpable peristomal mass. The colorectal surgeon schedules a colonoscopy via the stoma to evaluate the colonic lumen and surrounding tissues. During the procedure the provider advances the endoscope through the stoma, performs endoscopic ultrasound (EUS) to image the bowel wall and adjacent structures, and obtains intramural or transmural aspiration/biopsy samples from the sigmoid, descending, transverse, or ascending colon or cecum as indicated by ultrasound findings. The clinical workflow includes pre-procedure evaluation, informed consent, stoma-site preparation, sedation or anesthesia, stoma-directed colonoscopic access, EUS imaging, targeted aspiration/biopsy, specimen handling and labeling, post-procedure monitoring in recovery, and documentation of findings and pathology requests. This procedure is typically performed in an ambulatory surgery center, hospital endoscopy suite, or inpatient operating room depending on patient acuity and anesthesia needs.
