ICD-10 Code L89.001 – Pressure ulcer of unspecified elbow, stage 1 (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L89.001 – Pressure ulcer of unspecified elbow, stage 1
What it is
This code identifies a pressure ulcer on the elbow with intact skin and early localized damage. Stage 1 means the area is non-blanchable redness over a bony prominence, without an open wound.
Clinical signs
Look for persistent redness that does not blanch when pressed, with skin that remains intact. The area may feel warmer, firmer, or more painful than surrounding skin; clinical features vary, so refer to documentation.
When to use this code
Use this code when the provider documents a stage 1 pressure injury at the elbow and laterality is not specified. It is appropriate for early pressure-related skin damage with no skin breakdown. If the record says only “pressure ulcer” or gives a different stage, check documentation before assigning L89.001.
Do not use for
Do not use this code for stage 2, 3, 4, unstageable, or deep tissue pressure injuries. It is also not for non-pressure skin irritation, abrasions, or ulcers at other sites.
Coding tip
Verify both stage and location in the note; if the elbow side is not documented, this unspecified code is the correct choice.
