ICD-10 Code L89.302 – Pressure ulcer of unspecified buttock, stage 2 (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L89.302 – Pressure ulcer of unspecified buttock, stage 2
What it is
This code identifies a pressure ulcer on the buttock with stage 2 skin damage. Stage 2 means partial-thickness skin loss, often presenting as a shallow open sore or blister.
Clinical signs
Look for a localized wound over the buttock with partial-thickness loss of skin. The area may appear as an open ulcer or intact/ruptured blister; clinical features vary, so refer to documentation.
When to use this code
Use L89.302 when the record clearly documents a pressure ulcer on an unspecified buttock and identifies it as stage 2. This fits situations where the provider names the site but does not specify the left or right side. If the stage or location is unclear, check documentation.
Do not use for
Do not use this code for non-pressure skin breakdown, moisture-associated dermatitis, or wounds that are not documented as pressure ulcers. Also avoid it when a different buttock side or a different stage is specified.
Coding tip
Confirm both the pressure-ulcer stage and whether the buttock is unspecified before assigning L89.302.
