ICD-10 Code L89.620 – Pressure ulcer of left heel, unstageable (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L89.620 – Pressure ulcer of left heel, unstageable
What it is
This code identifies a pressure ulcer on the left heel whose true depth cannot be determined because the wound bed is covered by slough, eschar, or another barrier. Use it when staging is not possible from the available documentation.
Clinical signs
The ulcer is located on the left heel and has tissue loss consistent with pressure injury. Clinical features vary; refer to documentation, but unstageable ulcers typically have obscured wound depth and may show necrotic tissue or adherent drainage.
When to use this code
Use L89.620 when the provider documents an unstageable pressure ulcer of the left heel. This is appropriate when the heel wound cannot be staged because the base is covered and the depth is unknown. If later documentation clarifies a stage, code the documented stage instead.
Do not use for
Do not use this code for a left heel ulcer that is clearly staged, such as stage 1 through 4 or deep tissue pressure injury. Do not use it for non-pressure ulcers or wounds without documentation of pressure-related cause.
Coding tip
Query the provider if the heel wound is described as covered by eschar or slough but staging is not explicitly stated.
