Other renal tubulo-interstitial diseases
Chapter 14:Diseases of the genitourinary system
ICD-10 N15 is a billable code used to indicate a diagnosis of other renal tubulo-interstitial diseases.
N15 encompasses a variety of renal tubulo-interstitial diseases that affect the kidney's tubules and interstitial tissue. This category includes conditions such as pyelonephritis, which is an infection of the kidney often caused by urinary tract infections (UTIs), and interstitial nephritis, which can be due to drug reactions or infections. Hydronephrosis, characterized by the swelling of a kidney due to a build-up of urine, may also fall under this code when it is not due to obstruction. Drug-induced nephropathy is another significant condition, often resulting from medications that cause damage to the renal tubules. These diseases can lead to impaired kidney function and require careful management, including antibiotic therapy for infections and monitoring for potential nephrotoxicity from drugs. Accurate coding is essential for appropriate treatment and reimbursement, as these conditions can vary widely in etiology and management.
Detailed history of renal function, laboratory results, and treatment plans.
Patients with acute kidney injury due to interstitial nephritis or pyelonephritis.
Ensure documentation includes specific drug history and any potential nephrotoxic agents.
Thorough documentation of infection source, treatment regimens, and response to therapy.
Patients presenting with recurrent UTIs leading to pyelonephritis.
Document antibiotic susceptibility testing and treatment adjustments.
Used to evaluate hydronephrosis or renal masses.
Indicate the reason for imaging and findings.
Nephrology may require additional imaging for diagnosis.
N15 includes various renal tubulo-interstitial diseases such as acute and chronic interstitial nephritis, drug-induced nephropathy, and hydronephrosis not due to obstruction.
