Algoneurodystrophy, right forearm

This code describes algoneurodystrophy, also known as Complex Regional Pain Syndrome (CRPS) Type I, affecting the right forearm. This condition is characterized by chronic, severe pain, swelling, and changes in skin temperature and texture in the affected limb, typically following trauma or surgery, but without direct nerve injury.

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

• Ensure the documentation specifies "right forearm" to support laterality and anatomical site.
• Distinguish from CRPS Type II (causalgia), which involves confirmed nerve injury.
• Consider sequencing this code after any precipitating injury or surgical procedure, if applicable.
