ICD-10 Code L98.A212 – Non-pressure chronic ulcer of right forearm with fat layer exposed (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L98.A212 – Non-pressure chronic ulcer of right forearm with fat layer exposed
What it is
This code identifies a chronic, non-pressure ulcer on the right forearm with exposed subcutaneous fat. Use it when the wound is not caused by pressure injury and documentation confirms fat layer exposure.
Clinical signs
Clinical features include a persistent open sore on the right forearm with full-thickness skin loss reaching the fat layer. You may also see drainage, surrounding skin changes, or delayed healing; clinical features vary, so refer to documentation.
When to use this code
Use this code when the record clearly states a chronic ulcer on the right forearm and specifies fat layer exposure. It fits outpatient or inpatient documentation when the clinician describes a non-pressure ulcer and laterality is right. If the depth or chronicity is unclear, check documentation.
Do not use for
Do not use this code for pressure ulcers, traumatic wounds, or ulcers without documented fat layer exposure. If the site is not the right forearm, or the record does not confirm a chronic non-pressure ulcer, check documentation.
Coding tip
Verify laterality, ulcer type, and depth in the note before assigning L98.A212.
