Short answer · Medically reviewed summary · Last updated: 2026-05-08
An ostomy does not have a single, universal ICD code because it is a surgical procedure rather than a singular disease entity; however, it is typically classified under the Z93 category in ICD-10 (Artificial opening status) and V44 in ICD-9. These codes are used to identify that a patient has an ostomy, while the primary medical condition necessitating the surgery is coded separately. Why are there different ICD codes for an ostomy? Because an ostomy is a surgically created opening that allows for the diversion of waste, its classification depends on the specific anatomical location of the stoma.

An ostomy does not have a single, universal ICD code because it is a surgical procedure rather than a singular disease entity; however, it is typically classified under the Z93 category in ICD-10 (Artificial opening status) and V44 in ICD-9. These codes are used to identify that a patient has an ostomy, while the primary medical condition necessitating the surgery is coded separately.
Why are there different ICD codes for an ostomy?
Because an ostomy is a surgically created opening that allows for the diversion of waste, its classification depends on the specific anatomical location of the stoma. In the ICD-10 system, the Z93 series is used to denote the presence of an artificial opening, such as a colostomy, ileostomy, or urostomy. Similarly, in ICD-9, the V44 series serves the same purpose. Clinicians use these codes to document the presence of an ostomy for insurance and administrative tracking, while the underlying disease—such as Crohn’s disease, ulcerative colitis, or colorectal cancer—receives its own specific diagnostic code.
How is an ostomy categorized in medical billing?
When healthcare providers record an ostomy, they must distinguish between the status of the opening and the reason for the surgery. For example, a patient living with an ostomy may have a Z93.3 code for a colostomy, but the primary diagnosis remains the condition that required the procedure. Currently, 286 people with an ostomy have joined the DiseaseMaps.org community, sharing their experiences with these clinical classifications and the daily management of their stoma.
What are the common types of ostomies?
The specific coding for an ostomy often depends on the type of waste diversion required. The most frequent types include:
- Colostomy: A portion of the large intestine is brought to the surface of the abdomen.
- Ileostomy: The end of the small intestine is diverted to the abdominal wall.
- Urostomy: A procedure to divert urine away from a diseased or defective bladder.
Next steps
- Consult your surgeon or ostomy nurse to confirm the specific ICD-10 codes used for your medical documentation.
- Join the DiseaseMaps.org community to connect with 286 others living with an ostomy.
- Review your medical records to ensure that both your underlying condition and your ostomy status are accurately reflected.
