Complex regional pain syndrome I of right upper limb

This code describes a chronic pain condition affecting the right upper limb, characterized by severe pain, swelling, changes in skin temperature and color, and functional impairment, without evidence of nerve damage. It typically develops after an injury, surgery, or stroke, but the severity of pain is disproportionate to the initial event.

Use this code when documentation clearly indicates a diagnosis of Complex Regional Pain Syndrome Type I (CRPS I) specifically affecting the patient's right arm, forearm, or hand. This diagnosis is often made clinically based on the Budapest criteria, which should be reflected in the medical record.

• Ensure the documentation specifies "Type I" (reflex sympathetic dystrophy) as opposed to "Type II" (causalgia), which involves confirmed nerve injury.
• Verify laterality; this code is specific to the right upper limb. Use other codes for left or bilateral involvement.
• Look for supporting documentation of autonomic dysfunction, sensory abnormalities, motor/trophic changes, and edema in the affected limb.
