Type 2 diabetes mellitus w diabetic neuropathic arthropathy

This code signifies type 2 diabetes that has led to neuropathic arthropathy, commonly known as Charcot joint. This condition involves progressive joint destruction, often in the feet, due to nerve damage caused by chronic hyperglycemia. It results in bone and joint deformities, instability, and potential ulceration.

Apply this code when documentation explicitly states type 2 diabetes as the underlying cause of Charcot arthropathy. This typically involves findings such as foot deformities, joint subluxation, or bone destruction in a diabetic patient. Supporting documentation should include physician notes detailing the diabetic etiology of the arthropathy.

• Always ensure the documentation specifies "type 2 diabetes" and links it directly to the neuropathic arthropathy.
• Do not use this code if the arthropathy is not explicitly stated as neuropathic or if the diabetes type is not specified as type 2.
• Consider additional codes for associated complications such as diabetic foot ulcers (L97.-) or osteomyelitis (M86.-) if present and documented.
