Official Coding Guidelines

Pressure ulcer stages—L89 identifies site/stage; code all ulcers

a. Pressure ulcer stage codes 1) Pressure ulcer stages Codes in category L89, Pressure ulcer, identify the site and stage of the pressure ulcer. The ICD-10-CM classifies pressure ulcer stages based on severity, which is designated by stages 1-4, deep tissue pressure injury, unspecified stage, and unstageable. Assign as many codes from category L89 as needed to identify all the pressure ulcers the patient has, if applicable. See Section I.B.14. for pressure ulcer stage documentation by clinicians other than patient's provider.
