Abrasion of right forearm, sequela

This code indicates a superficial injury to the right forearm, characterized by scraping or rubbing off of the skin's outer layer, where the acute injury has resolved and the patient is presenting for treatment of a residual condition or complication. This could include scarring, chronic pain, or functional impairment directly resulting from the original abrasion.

Apply this code when a patient presents with a long-term effect or complication stemming from a previously sustained abrasion to the right forearm. This is appropriate for follow-up encounters addressing sequelae such as hypertrophic scarring, keloids, persistent dysesthesia, or contractures that developed after the initial injury healed.

• Always use this code as a secondary diagnosis, following the code for the specific sequela (e.g., L90.5 for scar conditions).
• Ensure documentation clearly links the current condition to the prior right forearm abrasion.
• Do not use for acute abrasions; those require codes from the S50.0-S50.8 range without the "S" seventh character.
