Pain in left arm

This code signifies unspecified pain localized to the left upper extremity. It indicates a symptom rather than a definitive diagnosis, suggesting discomfort or aching in the left arm without further specification of its underlying cause or precise anatomical location within the arm.

Use this code when documentation clearly states "pain in left arm" without additional details regarding etiology, specific joint involvement, or more precise anatomical location (e.g., shoulder, elbow, wrist). It is appropriate when the provider has not yet determined the definitive cause of the pain or when the pain is generalized to the entire left arm.

• Always seek more specific documentation if available, such as pain in left shoulder (M25.512) or left elbow (M25.522).
• This code should generally be used as a primary diagnosis only when a more specific diagnosis is not established or documented.
• Avoid using this code if the pain is clearly neuropathic (e.g., G54.0 for brachial plexus disorders) or related to a specific injury (e.g., S40-S49 for shoulder/upper arm injuries).
