Injury of musculocutaneous nerve, right arm, sequela

This code signifies a long-term or residual effect resulting from a previous injury to the musculocutaneous nerve in the patient's right arm. These sequelae can manifest as persistent weakness, sensory deficits, or chronic pain in the muscles innervated by this nerve, such as the biceps and brachialis. The injury itself is no longer acute, but its lasting impact continues to affect the patient.

Apply this code when documenting conditions like chronic muscle atrophy, persistent paresthesia, or ongoing functional limitations in the right arm, directly attributable to a past musculocutaneous nerve injury. This is appropriate for follow-up encounters where the original injury has healed, but its lasting consequences are being addressed.

• Ensure documentation clearly links the current condition to a previous musculocutaneous nerve injury of the right arm.
• The "S" in the 7th character indicates a sequela, meaning the initial injury has resolved, and the current encounter addresses its late effects.
• Do not use this code for acute injuries; instead, select an appropriate acute injury code for the initial encounter.
