ICD-10 Code L89.9 – Pressure ulcer of unspecified site (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L89.9 – Pressure ulcer of unspecified site
What it is
This code identifies a pressure ulcer when the site is not documented. It tells you a pressure injury is present, but the record does not specify the body location.
Clinical signs
Clinical features vary; refer to documentation. Pressure ulcers are typically localized skin or tissue breakdown over a bony prominence, often with redness, open skin, or deeper tissue loss.
When to use this code
Use L89.9 when the provider documents a pressure ulcer but does not identify the anatomic site. It may also fit when the chart confirms a pressure injury and location remains unclear after review. If the site is later documented, code the more specific L89 category instead.
Do not use for
Do not use this code if the ulcer site is documented elsewhere in the record. Do not use it for non-pressure ulcers or skin breakdown from another cause; check documentation.
Coding tip
Always search the full chart for the ulcer location before assigning L89.9.
