ICD-10 Code L98.432 – Non-pressure chronic ulcer of abdomen with fat layer exposed (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L98.432 – Non-pressure chronic ulcer of abdomen with fat layer exposed
What it is
This code identifies a chronic, non-pressure ulcer on the abdomen that extends through the skin into the fat layer. Use it when the wound is not caused by pressure, such as a pressure injury.
Clinical signs
Findings usually include an open abdominal wound with visible subcutaneous fat, delayed healing, and surrounding skin changes. Clinical features vary; refer to documentation.
When to use this code
Use L98.432 when the record clearly states a chronic ulcer of the abdomen with fat layer exposed and does not describe pressure-related injury. It may apply to long-standing wounds, surgical-site breakdown, or other non-pressure causes if the provider documents the ulcer site and depth. Check documentation for chronicity and location.
Do not use for
Do not use this code for pressure ulcers, superficial skin breakdown, or ulcers without fat layer exposure. If the site or depth is unclear, check documentation.
Coding tip
Confirm both the abdominal location and fat layer exposure in the provider note before assigning this code.
