Corrosion of first degree of unsp scapular region, sequela

This code signifies a first-degree burn-like injury (corrosion) to an unspecified area of the shoulder blade region, where the acute injury has healed and the patient is now presenting for treatment of a residual condition or complication directly related to that past injury. First-degree corrosions involve only the epidermis, causing redness and mild pain without blistering.

Apply this code when documenting a sequela, such as a scar, contracture, or chronic pain, resulting from a previously sustained first-degree chemical burn to the scapular region. This code is appropriate when the initial acute injury has resolved, and the current encounter addresses a long-term effect.

• Always use this code as a secondary diagnosis, following the code for the specific sequela being treated.
• Ensure documentation clearly links the current condition to a past first-degree corrosion of the scapular region.
• Avoid using this code for acute first-degree corrosions; it is exclusively for sequela.
