Inj cutan sensory nerve at shldr/up arm, unsp arm, sequela

This code signifies a long-term complication or residual effect stemming from a past injury to a cutaneous sensory nerve in the shoulder or upper arm region. The specific arm affected is not documented, and the precise nature of the nerve injury is unspecified. This typically involves persistent sensory deficits such as numbness, tingling, or altered sensation.

Apply this code when a patient presents with a sequela (e.g., chronic paresthesia, dysesthesia, or anesthesia) directly attributable to a previous injury of a cutaneous sensory nerve in the shoulder or upper arm. This is appropriate when the original injury has healed, but the nerve damage's lasting effects are still present and the affected arm is not specified in the documentation.

• Always use a seventh character of 'S' for sequela when documenting a late effect of an injury.
• Ensure documentation clearly links the current sensory deficit to a prior injury of a cutaneous sensory nerve.
• Avoid using this code if the specific nerve or arm is known and can be coded more precisely.
