Pain in unspecified upper arm

This code signifies generalized pain experienced in the upper arm, without further specification of laterality (left or right) or a more precise anatomical location within the upper arm. It indicates a symptom rather than a definitive diagnosis of an underlying condition.

This code is appropriate when a patient presents with upper arm pain, and the medical record does not specify whether the pain is in the left or right arm. It is used when the provider's documentation clearly states "unspecified upper arm pain" or similar, and no further diagnostic information is available at the time of coding.

• Avoid using this code if laterality (left or right) is documented; instead, choose a more specific code (e.g., M79.621 for right, M79.622 for left).
• Always query the provider for more specific documentation regarding laterality and the underlying cause of the pain if possible.
• This code should generally be considered a last resort when more specific pain codes are not supported by the documentation.
