Other renal tubulo-interstitial diseases (N15)
ICD-10 code section N15 covers a group of diseases affecting the renal tubules and surrounding interstitial tissue within the kidneys. These codes are specifically used for conditions beyond common kidney inflammations, focusing on diverse and sometimes rare kidney disorders.
The ICD-10 code for Balkan nephropathy (N15.0) identifies a regional kidney disease known for causing chronic tubulointerstitial damage. Code N15.1 is assigned to renal and perinephric abscesses, which are collections of pus in or around the kidney, including related conditions known as retroperitoneal or perirenal abscesses. N15.8 covers other specified tubulo-interstitial diseases such as fungal infections of the kidney or Armanni-Ebstein kidney. When the kidney disease is tubulointerstitial but not well defined, code N15.9 is used, including conditions like BK virus nephropathy after renal transplant or hereditary tubulointerstitial disorders. These codes help healthcare providers and coders accurately capture less common renal diseases beyond typical nephritis or nephrosis.
Clinical Terms
The following clinical terms provide additional context, helping users better understand the clinical background and common associations for each diagnosis listed in this section. Including related terms alongside ICD-10-CM codes supports coders, billers, and healthcare professionals in improving accuracy, enhancing documentation, and facilitating research or patient education.
Balkan Nephropathy
A form of chronic interstitial nephritis that is endemic to limited areas of BULGARIA, the former YUGOSLAVIA, and ROMANIA. It is characterized by a progressive shrinking of the KIDNEYS that is often associated with uroepithelial tumors.
Kidney
Body organ that filters blood for the secretion of URINE and that regulates ion concentrations.
Perinephritis
Inflammation of the connective and adipose tissues surrounding the KIDNEY.
