Burn of third degree of unspecified forearm, sequela

This code indicates a third-degree burn affecting an unspecified forearm, where the current encounter is for the treatment of a late effect or complication of the original burn injury. Third-degree burns involve full-thickness skin destruction, often extending into subcutaneous tissue, and sequelae can include scarring, contractures, chronic pain, or functional impairment.

This code is appropriate when a patient presents for management of a long-term consequence directly resulting from a previously sustained third-degree burn to an unspecified forearm. Examples include surgical revision of a burn scar, treatment of a contracture limiting forearm movement, or management of chronic neuropathic pain related to the burn. It should not be used for the initial acute treatment of the burn.

• Always assign an additional code to specify the nature of the sequela (e.g., L90.5 for scar conditions, M24.5x for contracture).
• Ensure documentation clearly indicates the encounter is for a late effect and not an active burn injury.
• Verify the specific forearm (right or left) is not documented; if specified, a more precise code should be used.
