Unsp superficial injury of unspecified forearm, sequela

This code signifies a long-term consequence or late effect of a superficial injury to an unspecified forearm, where the exact nature of the initial injury (e.g., abrasion, contusion, insect bite) is not documented. It indicates that the patient is presenting for care related to a residual condition stemming from a past, ill-defined superficial forearm trauma.

Use this code when a patient presents with a sequela (e.g., scar tissue, chronic pain, altered sensation) directly attributable to a previously sustained, unspecified superficial injury of an unspecified forearm. This code is appropriate when the acute phase of the original injury has passed, and the current encounter addresses the lasting effects.

• Always use this code as a secondary diagnosis, following the code for the specific sequela being treated.
• Avoid using this code if the specific type of superficial injury (e.g., abrasion, contusion) is known and documented, even if it's a sequela.
• Ensure the "S" seventh character is appended for sequela, indicating a late effect of the injury.
