Charcot's joint, left hand

This code represents Charcot's arthropathy affecting the left hand. This is a progressive, degenerative arthropathy resulting from nerve damage, leading to joint destruction, deformity, and instability in the absence of pain. It is often associated with underlying neurological conditions such as diabetes, syphilis, or syringomyelia.

Use this code when documentation clearly indicates a diagnosis of Charcot's joint specifically affecting the left hand. Supporting documentation should detail the characteristic joint destruction, deformity, and neurological deficit consistent with neuropathic arthropathy. This code is appropriate for both initial and subsequent encounters for this condition.

• Ensure laterality is precisely documented; do not use for bilateral or unspecified hand involvement.
• Always code the underlying neurological condition (e.g., diabetes mellitus with neurological complications) first, as Charcot's arthropathy is a manifestation of that primary disease.
• Differentiate from other forms of degenerative arthritis; Charcot's joint has a distinct neuropathic etiology.
