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

This code signifies damage to the sensory nerves located in the skin of the shoulder and upper arm. This injury affects the ability to feel sensations in the affected area, without specifying which arm is involved. It represents the initial presentation of such an injury.

Use this code for patients presenting with new onset numbness, tingling, or altered sensation in the skin of the shoulder or upper arm, where the specific nerve involved is not yet identified. This applies to cases resulting from trauma, compression, or other acute insults to the cutaneous sensory nerves.

• Ensure documentation clearly states "initial encounter" for the injury.
• Only use this code when the specific cutaneous sensory nerve (e.g., lateral brachial cutaneous nerve) is not documented.
• If the laterality (left or right arm) is known, a more specific code should be used.
