L98.438
ICD-10-CMNon-pressure chronic ulcer of abdomen with other specified severity
This code describes a long-standing open sore or lesion on the abdominal wall that is not caused by pressure. It indicates a chronic ulceration in this specific anatomical location, with the "other specified severity" indicating that the ulcer's depth or tissue involvement is documented but does not fit into categories like "limited to skin breakdown" or "fat layer exposed."
Use this code for patients presenting with a chronic, non-healing ulcer on the abdomen where the medical record specifies a severity beyond superficial skin involvement, but not reaching muscle or bone. Documentation should clearly state the ulcer's chronicity, its non-pressure etiology, its abdominal location, and a description of its depth or tissue involvement that falls outside of defined stages.
