ICD-10 Code L89.93 – Pressure ulcer of unspecified site, stage 3 (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L89.93 – Pressure ulcer of unspecified site, stage 3
What it is
This code identifies a pressure ulcer with stage 3 depth when the site is not specified in the record. Stage 3 means full-thickness skin loss with visible subcutaneous tissue, but no exposed muscle, tendon, or bone.
Clinical signs
Look for a full-thickness ulcer, often appearing as a deep open crater with adipose tissue visible. Clinical features vary; refer to documentation if the note does not clearly describe staging or tissue depth.
When to use this code
Use L89.93 when the provider documents a stage 3 pressure ulcer but does not name the body site. It also fits when the record confirms stage 3 depth and laterality or location is unavailable. Check documentation if the note is incomplete or conflicting.
Do not use for
Do not use this code for stage 1, stage 2, unstageable, or deep tissue pressure injuries. Also avoid it when the site is documented, since a more specific pressure ulcer code may apply.
Coding tip
If the site is missing, code the documented stage only and query for location when needed.
