Toxic nephropathy, not elsewhere classified
ICD-10 N14.4 is a billable code used to indicate a diagnosis of toxic nephropathy, not elsewhere classified.
Toxic nephropathy refers to kidney damage resulting from exposure to toxic substances, which can include drugs, heavy metals, and other environmental toxins. This condition can manifest as acute or chronic kidney injury, leading to a range of clinical symptoms such as decreased urine output, fluid retention, and electrolyte imbalances. Pyelonephritis, interstitial nephritis, and drug-induced nephropathy are common forms of toxic nephropathy. Pyelonephritis is an infection of the kidney that can occur secondary to urinary tract infections (UTIs), while interstitial nephritis is characterized by inflammation of the kidney interstitium, often due to medications or infections. Hydronephrosis, the swelling of a kidney due to a build-up of urine, can also be a complication of toxic nephropathy. Management typically involves identifying and removing the offending agent, supportive care, and in some cases, antibiotic therapy to treat underlying infections. Accurate diagnosis and coding are crucial for appropriate treatment and reimbursement.
Detailed patient history, lab results, and imaging studies to confirm diagnosis.
Patients presenting with acute kidney injury following medication use or exposure to toxins.
Ensure clear documentation of the toxic agent and its effects on kidney function.
Documentation of urinary tract infections and their management, including antibiotic therapy.
Patients with recurrent UTIs leading to pyelonephritis and subsequent nephropathy.
Document the relationship between infections and nephropathy clearly.
Used to assess kidney function and electrolyte levels in patients with suspected nephropathy.
Document the rationale for testing and results.
Nephrology specialists should ensure all relevant lab results are included.
Common causes include exposure to nephrotoxic medications (like NSAIDs, antibiotics), heavy metals (like lead or mercury), and certain environmental toxins.
