ICD-10 Code L89.41 – Pressure ulcer of contiguous site of back, buttock and hip, stage 1 (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L89.41 – Pressure ulcer of contiguous site of back, buttock and hip, stage 1
What it is
This code identifies a pressure ulcer affecting the combined back, buttock, and hip area at stage 1. Stage 1 means the skin is intact but shows nonblanchable redness over a bony prominence.
Clinical signs
Look for localized redness that does not turn white when pressed, with intact skin over the affected area. Clinical features vary; refer to documentation if the note does not clearly describe stage 1 findings.
When to use this code
Use this code when the provider documents a stage 1 pressure ulcer in the contiguous back, buttock, and hip region. It is appropriate when the site is specified as this combined area and there is no skin breakdown beyond erythema. If the stage or location is unclear, check documentation before coding.
Do not use for
Do not use this code for pressure injuries at another site, such as the sacrum, heel, or ankle. Do not assign it if the ulcer is deeper than stage 1 or if the record does not support pressure ulcer staging.
Coding tip
Confirm both the exact anatomic site and the stage in the provider note before assigning L89.41.
