Unspecified superficial injury of left upper arm, sequela

This code indicates a past, unresolved superficial injury to the left upper arm, where the specific type of superficial injury (e.g., abrasion, contusion, blister) was not documented at the time of the initial injury or is unknown. It signifies a long-term effect or complication arising from such an injury.

Apply this code when a patient presents with a current condition or symptom that is a direct result of a previously sustained, unspecified superficial injury to their left upper arm. This is appropriate for follow-up care or when evaluating chronic issues stemming from the original trauma, and the initial injury itself is no longer acute.

• Always use this code as a secondary diagnosis, following the code for the current condition or sequela being treated.
• Ensure documentation clearly links the current problem to a past, unspecified superficial injury of the left upper arm.
• Confirm that the "S" seventh character is appropriate, indicating a sequela, rather than an initial encounter or subsequent encounter for an acute injury.
