ICD-10 Code L89.899 – Pressure ulcer of other site, unspecified stage (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L89.899 – Pressure ulcer of other site, unspecified stage
What it is
This code identifies a pressure ulcer located at an “other site” not named in the code set, when the stage is not documented. Use it for a pressure injury caused by prolonged pressure, but the chart does not specify the stage.
Clinical signs
Clinical features vary; refer to documentation. Pressure ulcers may show localized skin breakdown, discoloration, or an open wound over a pressure-bearing area, but staging must be recorded to code more specifically.
When to use this code
Use L89.899 when the provider documents a pressure ulcer at a non-listed site and does not state the stage. It is appropriate when the location is clear enough for “other site,” but the record lacks stage details. Check documentation if the site or staging is unclear.
Do not use for
Do not use this code for pressure ulcers with a documented stage, or when the ulcer site is specifically named elsewhere in the code set. Do not guess the stage from wound appearance alone.
Coding tip
Query for the exact site and stage whenever the note is incomplete, because both details affect code selection.
