Pain in limb

This code represents a patient's subjective complaint of pain localized to an extremity, such as an arm, leg, hand, or foot, without a more specific diagnosis yet established. It indicates discomfort or aching in a limb that is not attributable to a fracture, sprain, nerve impingement, or other definitive musculoskeletal or neurological condition at the time of coding.

Use this code when documentation clearly states "pain in limb," "extremity pain," or similar, and no further diagnostic information is available to specify the cause or anatomical site more precisely. It is appropriate for initial encounters or when the underlying etiology of the limb pain is still under investigation. Documentation should clearly indicate the limb affected (e.g., right arm pain, left leg pain) if known, but this code is for generalized limb pain.

• Always strive for a more specific diagnosis if available, such as neuritis, arthritis, or specific joint pain.
• Do not use this code if the pain is clearly localized to a joint (e.g., knee pain, shoulder pain); use the appropriate joint pain code instead.
• This is a symptom code; it should be sequenced as the primary diagnosis when the reason for the encounter is the limb pain itself, and no definitive diagnosis has been made.
