ICD-10 Code L89.149 – Pressure ulcer of left lower back, unspecified stage (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L89.149 – Pressure ulcer of left lower back, unspecified stage
What it is
This code identifies a pressure ulcer located on the left lower back when the stage is not documented. It is used for a localized skin and tissue injury caused by prolonged pressure over that area.
Clinical signs
Findings may include intact skin, an open sore, or tissue breakdown over the left lower back. Clinical features vary; refer to documentation and the recorded stage if available.
When to use this code
Use this code when the provider documents a pressure ulcer on the left lower back but does not specify the stage. It is also appropriate when the note clearly identifies the site and confirms pressure-related injury, but staging is missing or unavailable. Check documentation if the location is described differently.
Do not use for
Do not use this code for ulcers at other body sites or for wounds that are not pressure-related. If the stage is documented, assign the more specific pressure ulcer code instead.
Coding tip
Verify both laterality and site wording in the note before coding, because “left lower back” must be documented clearly.
