Lead-induced chronic gout, right hip, without tophus (tophi)

This code signifies a persistent inflammatory arthritis affecting the right hip joint, caused by elevated lead levels in the body. The condition is characterized by recurrent attacks of pain and swelling due to uric acid crystal deposition, but without the presence of visible or palpable tophi.

Apply this code when documentation confirms a diagnosis of chronic gout specifically attributed to lead exposure, impacting the right hip. The absence of tophaceous deposits must also be explicitly stated or clearly implied. Supporting documentation would include laboratory results indicating lead toxicity and uric acid levels, along with imaging and clinical notes detailing chronic right hip gout symptoms.

• Ensure documentation clearly links the chronic gout to lead exposure.
• Verify the affected joint is specifically the right hip; laterality is crucial.
• Confirm the absence of tophi; if tophi are present, a different code is required.
