Corrosion of second degree of unspecified shoulder, sequela

This code signifies a second-degree chemical burn (corrosion) affecting an unspecified shoulder, where the patient is presenting for treatment of a late effect or complication of the original injury. This indicates that the acute phase of the corrosion has passed, and the current encounter addresses residual problems such as scarring, contractures, or chronic pain resulting from the initial chemical exposure.

Use this code when documenting follow-up care for a patient who previously sustained a second-degree chemical burn to the shoulder and is now experiencing long-term consequences. This applies to scenarios like surgical revision of scar tissue, physical therapy for range of motion limitations, or management of persistent discomfort directly attributable to the past corrosion.

• Always sequence this code after the code(s) for the specific sequela being treated (e.g., scar, contracture).
• Ensure documentation clearly links the current condition to the previous second-degree chemical burn of the shoulder.
• Avoid using this code for acute or initial treatment of the chemical burn; instead, use the appropriate acute corrosion code.
