Pressure ulcer of unspecified site, stage 2

This code represents a partial-thickness skin loss involving the epidermis and/or dermis, presenting as a shallow open ulcer with a red-pink wound bed, without slough. It may also appear as an intact or ruptured serum-filled blister. The specific anatomical location of the pressure ulcer is not documented or is unknown.

Apply this code when documentation clearly indicates a Stage 2 pressure ulcer, but the precise anatomical site (e.g., sacrum, heel, ischium) is not specified by the provider. This is appropriate for initial encounters or when the site is not yet determined.

• Avoid using this code if the anatomical site is documented; instead, use a more specific code from the L89.xxx series.
• Do not use for suspected deep tissue injury or unstageable pressure ulcers.
• Ensure the documentation explicitly states "Stage 2" or describes the characteristic features of a Stage 2 ulcer.
