Corrosion of unsp degree of unspecified upper arm, sequela

This code signifies the long-term effects or complications resulting from a chemical burn of an unspecified degree affecting an unspecified part of the upper arm. It indicates that the initial injury has healed, but residual issues such as scarring, contractures, or chronic pain persist.

Apply this code when documenting follow-up care for a patient experiencing ongoing problems directly attributable to a past chemical burn of the upper arm. This includes scenarios where the original burn was not fully characterized by degree, and the specific location on the upper arm was not documented. It is used after the acute phase of the injury has passed.

• Always sequence this code after the code(s) identifying the specific sequela (e.g., scar, contracture).
• Ensure documentation clearly links the current condition to a previous chemical burn of the upper arm.
• Avoid using this code for acute or active chemical burns; it is strictly for residual conditions.
