Nephropathy induced by heavy metals
ICD-10 N14.3 is a billable code used to indicate a diagnosis of nephropathy induced by heavy metals.
Nephropathy induced by heavy metals refers to kidney damage resulting from exposure to toxic metals such as lead, mercury, cadmium, and arsenic. These metals can cause various forms of kidney injury, including acute interstitial nephritis and chronic kidney disease. The pathophysiology involves direct cellular toxicity, leading to inflammation and fibrosis within the renal interstitium. Symptoms may include proteinuria, hematuria, and decreased renal function. Heavy metal nephropathy can also predispose patients to secondary complications such as pyelonephritis due to urinary tract infections (UTIs), which may arise from urinary stasis or obstruction. Management often involves removing the source of exposure, supportive care, and in some cases, chelation therapy. Antibiotic management may be necessary for associated UTIs, particularly in cases where hydronephrosis is present due to obstructive uropathy. Accurate diagnosis and coding are essential for appropriate treatment and reimbursement.
Detailed history of exposure to heavy metals, renal function tests, and imaging studies.
Patients presenting with renal impairment and a history of occupational or environmental exposure to heavy metals.
Ensure that all relevant lab results and imaging studies are documented to support the diagnosis.
Documentation of urinary tract infections, including culture results and antibiotic sensitivity.
Patients with nephropathy who develop UTIs or pyelonephritis.
Document the relationship between nephropathy and urinary infections to support coding.
Used to evaluate renal function and detect urinary tract infections.
Document the reason for urinalysis and any findings.
Nephrology and Infectious Disease specialists should ensure comprehensive documentation.
Common heavy metals include lead, mercury, cadmium, and arsenic, each of which can cause varying degrees of renal damage.
