Lead-induced chronic gout, unspecified hip, with tophus

This code signifies a chronic inflammatory arthritis caused by elevated lead levels, specifically affecting an unspecified hip joint. The presence of tophi, which are deposits of uric acid crystals, further characterizes this condition. This represents a long-standing form of gout with a known toxic etiology.

Apply this code when documentation clearly indicates chronic gout attributed to lead exposure, with evidence of tophaceous deposits in the hip. This diagnosis requires a history of lead poisoning or elevated lead levels, along with clinical or imaging findings consistent with gout and tophi in the hip region.

• Ensure documentation specifies "chronic" gout and a clear link to "lead-induced" etiology.
• Verify the presence of "tophus" or "tophi" in the medical record.
• Do not use if the specific hip (left or right) is documented; use the more specific codes available.
