ICD-10 Code L89.623 – Pressure ulcer of left heel, stage 3 (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L89.623 – Pressure ulcer of left heel, stage 3
What it is
This code identifies a pressure ulcer on the left heel with full-thickness skin loss consistent with stage 3. It means the wound extends into the subcutaneous tissue, but bone, tendon, and muscle are not exposed.
Clinical signs
Look for an open ulcer over the left heel with visible depth and loss of skin layers. Stage 3 ulcers may show slough, undermining, or tunneling; clinical features vary, so refer to documentation.
When to use this code
Use L89.623 when the provider documents a pressure ulcer of the left heel and specifies stage 3. This applies when the stage is confirmed in the record, such as wound assessment, progress notes, or discharge documentation. If laterality or stage is unclear, check documentation before coding.
Do not use for
Do not use this code for a left heel pressure injury documented as stage 1, stage 2, stage 4, or unstageable. Also avoid it if the ulcer is on a different site or the record does not confirm stage 3.
Coding tip
Verify both the anatomic site and the stage in the same source note before assigning L89.623.
