Injury of median nerve at upper arm level, unsp arm, subs

This code signifies a documented injury to the median nerve occurring in the upper arm region, without specifying which arm is affected. It is used when the patient is receiving active treatment for the injury after the initial phase of care, such as during follow-up appointments, cast changes, or medication adjustments.

This code is appropriate for patients presenting for ongoing management of a median nerve injury in the upper arm, where the specific arm (left or right) was not documented or is unknown. Examples include physical therapy sessions, re-evaluations of nerve function, or wound care related to the initial injury.

• Ensure documentation clearly indicates the injury is to the median nerve and located in the upper arm.
• Verify the encounter is for subsequent care, not the initial treatment or sequelae.
• If the laterality (left or right arm) is specified in the documentation, a more specific code should be used.
