ICD-10 from 2011 - 2016
Billable Code
Billable codes are sufficient justification for admission to an acute care hospital when used a principal diagnosis.Manifestation Code
Certain ICD-10-CM codes identify an underlying condition known as an etiology code. Conditions that arise as a result of an underlying condition (etiology), are referred to as Manifestations. In ICD-10-CM, etiology codes must be coded first, followed by the manifestation codes. When a condition requires etiology and manifestation codes, there is a "use additional code" note following the etiology code and a "code first" note following the manifestation code.N16 is a billable ICD code used to specify a diagnosis of renal tubulo-interstitial disorders in diseases classified elsewhere. A 'billable code' is detailed enough to be used to specify a medical diagnosis.
The ICD code N16 is used to code Tubulopathy
Tubulopathy is a disease affecting the renal tubules of the nephron.

Type-1 Excludes
Type-1 Excludes mean the conditions excluded are mutually exclusive and should never be coded together. Excludes 1 means "do not code here." - Diphtheritic pyelonephritis and tubulo-interstitial nephritis - instead, use code A36.84
- Pyelonephritis and tubulo-interstitial nephritis in candidiasis - instead, use code B37.49
- Pyelonephritis and tubulo-interstitial nephritis in cystinosis - instead, use code E72.04
- Pyelonephritis and tubulo-interstitial nephritis in salmonella infection - instead, use code A02.25
- Pyelonephritis and tubulo-interstitial nephritis in sarcoidosis - instead, use code D86.84
- Pyelonephritis and tubulo-interstitial nephritis in sicca syndrome [Sjogren's] - instead, use code M35.04
- Pyelonephritis and tubulo-interstitial nephritis in systemic lupus erythematosus - instead, use code M32.15
- Pyelonephritis and tubulo-interstitial nephritis in toxoplasmosis - instead, use code B58.83
- Renal tubular degeneration in diabetes - instead, use Section E08-E13 with .29)
- Syphilitic pyelonephritis and tubulo-interstitial nephritis - instead, use code A52.75

(approximate match)
This is the official approximate match mapping between ICD9 and ICD10, as provided by the General Equivalency mapping crosswalk. This means that while there is no exact mapping between this ICD10 code N16 and a single ICD9 code, 590.81 is an approximate match for comparison and conversion purposes.
