Renal tubulo-interstitial diseases (N10-N16)
ICD-10 codes N10-N16 cover diseases affecting the kidney’s tubules and surrounding interstitial tissue, including acute and chronic pyelonephritis, obstructive uropathies, drug-induced nephropathies, and renal disorders linked with other diseases. These codes are used to specify detailed diagnoses for tubulo-interstitial kidney conditions.
This code range includes N10 for acute pyelonephritis, also known as acute tubulo-interstitial nephritis or emphysematous pyelonephritis, covering various infectious or immunologic acute kidney inflammations. Chronic forms are coded under N11, such as reflux-associated or obstructive chronic pyelonephritis. Obstructive and reflux uropathies, like hydronephrosis due to ureteral blockages (N13 codes), cover conditions causing urinary tract obstruction or vesicoureteral reflux, which may lead to renal damage. Drug- and heavy-metal-induced nephropathies (N14) identify kidney disorders from substances like analgesics, contrast media, or heavy metals. Other specific or unspecified tubulo-interstitial disorders, as well as those related to systemic diseases like Immunoglobulin G4-related kidney disease, fall under N15 and N16. These detailed codes assist clinicians and coders in accurately documenting the diverse tubulo-interstitial kidney diseases encountered in practice.

Instructional Notations
Includes
This note appears immediately under a three character code title to further define, or give examples of, the content of the category.
- pyelonephritis
Type 1 Excludes
A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.
