ICD-10-CM Code For Other Renal Tubulo Interstitial Diseases: Group Overview
The International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) code group N15 includes disorders of the renal tubules and interstitium such as renal tubular acidosis, interstitial nephritis, and other specified tubulo-interstitial kidney diseases that impair tubular function and may lead to chronic kidney injury. These ICD-10-CM diagnosis codes are used to document clinical scenarios involving tubular dysfunction, interstitial inflammation or fibrosis, and associated electrolyte or acid-base disturbances, capturing disease severity and organ involvement. Accurate coding within the ICD-10-CM N15 group supports proper claim adjudication, complete clinical documentation, and appropriate reimbursement.

ICD-10-CM N15: Other Renal Tubulo-Interstitial Diseases Overview
The diagnoses in the ICD-10-CM N15 group represent non-glomerular kidney disorders that primarily affect the renal tubules and interstitial tissue. These conditions involve tubular dysfunction, interstitial inflammation or fibrosis, and can lead to impaired renal concentrating, electrolyte disturbances, or chronic kidney disease. Accurate coding matters for proper clinical documentation and may affect reimbursement and longitudinal care planning.
