In simple words: Lead poisoning can cause a type of arthritis called gout. This happens because lead can damage the kidneys, which then can't remove a waste product called uric acid from the blood.The uric acid builds up and forms crystals in the joints, causing pain and swelling.

Gout caused by chronic lead intoxication, from either occult or occupational exposure or the ingestion of moonshine. Lead poisoning causes damage to the kidney, leading to uric acid retention and crystal formation, causing joint inflammation. Symptoms may include abdominal pain, nerve palsies, hypertension, vomiting, and kidney failure.

Example 1: A 50-year-old man with a history of moonshine consumption presents with severe pain and swelling in his big toe. Blood tests reveal elevated lead and uric acid levels, confirming a diagnosis of lead-induced gout., A worker in a battery factory experiences joint pain and swelling after chronic lead exposure.Elevated lead and uric acid levels lead to the diagnosis of M10.1., A child living in an older house with lead paint develops digestive issues and joint pain. Upon examination, the child has elevated blood lead levels and evidence of gout, thus coded as M10.1.

Documentation should include evidence of lead exposure (occupational history, environmental factors), clinical findings of gout (joint pain, swelling, redness), imaging studies (X-rays), and laboratory results showing elevated lead and uric acid levels.
