Charcot's joint, right ankle and foot

This code describes Charcot's arthropathy affecting the right ankle and/or foot. This is a progressive, degenerative arthropathy resulting from nerve damage, often associated with diabetes, leading to joint destruction, deformity, and instability.

Use this code for patients diagnosed with neuropathic osteoarthropathy specifically involving the right ankle or foot. Documentation should clearly indicate the diagnosis of Charcot's joint and specify the affected laterality as the right ankle and/or foot.

• Always confirm the laterality (right vs. left) and the specific joint(s) affected (ankle, foot, or both).
• Code the underlying cause of the Charcot's joint (e.g., E10.40 for Type 1 diabetes with neurological complications) first, followed by this code.
• Distinguish from other forms of arthritis or osteomyelitis, which have different ICD-10-CM codes.
