Algoneurodystrophy, right hand

This code signifies algoneurodystrophy, also known as Complex Regional Pain Syndrome (CRPS) Type I, specifically affecting the right hand. It describes a chronic pain condition characterized by severe pain, swelling, changes in skin temperature and color, and functional impairment in the affected limb, without nerve injury.

Use this code when documentation clearly indicates a diagnosis of CRPS Type I localized to the patient's right hand. Supporting documentation should detail the characteristic symptoms of CRPS, such as allodynia, hyperalgesia, edema, sudomotor abnormalities, and trophic changes, specifically in the right hand.

• Ensure the documentation specifies "right hand" to support this laterality.
• Distinguish from CRPS Type II (causalgia), which involves a confirmed nerve injury.
• Consider sequencing this code as a primary diagnosis if it is the main reason for the encounter.
