ICD-10 Code L89.891 – Pressure ulcer of other site, stage 1 (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L89.891 – Pressure ulcer of other site, stage 1
What it is
This code identifies a pressure ulcer at an unspecified “other site” that is limited to stage 1 skin changes. Stage 1 means intact skin with nonblanchable redness over a pressure area.
Clinical signs
Look for localized erythema that does not blanch when pressed, with skin still intact. Clinical features vary; refer to documentation if the site, depth, or staging is unclear.
When to use this code
Use it when the record documents a pressure injury at a site not named in the code set and the ulcer is clearly stage 1. You should code from provider documentation, including the pressure area and stage. If the site is described only as “other,” this code fits when no more specific site is given.
Do not use for
Do not use this code for non-pressure skin redness, friction injuries, or ulcers at a more specific anatomic site. Do not assign it if the stage is deeper than stage 1 or if documentation is insufficient.
Coding tip
Confirm both the pressure-ulcer stage and that the site truly belongs in the “other site” category before coding.
