ICD-10 Code L89.90 – Pressure ulcer of unspecified site, unspecified stage (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L89.90 – Pressure ulcer of unspecified site, unspecified stage
What it is
This code identifies a pressure ulcer when the site is not documented and the stage is not specified. Use it only when the record confirms a pressure injury but leaves both details unclear.
Clinical signs
Clinical features vary; refer to documentation. Common findings include localized skin breakdown over a pressure point, with possible redness, open skin, or tissue loss, but the exact location and stage are not recorded.
When to use this code
Use this code when the provider documents a pressure ulcer but does not identify the site or stage. It may also fit when the note says “pressure injury” without enough detail to assign a more specific code. Query if the record is unclear.
Do not use for
Do not use this code if the ulcer site is known or if the stage is documented, because a more specific code is available. Do not use it for non-pressure wounds or skin breakdown from other causes.
Coding tip
Always check the wound note, nursing documentation, and provider assessment before defaulting to L89.90.
