N14.1Nephropathy induced by other drugs, medicaments and biological substances

N14.1 is the ICD-10-CM diagnosis code for nephropathy induced by other drugs, medicaments and biological substances. It belongs to category N14 (Drug- and heavy-metal-induced tubulo-interstitial and tubular conditions), block N10-N16 (renal tubulo-interstitial diseases) and chapter 14 (diseases of the genitourinary system). It is a header code, so it can't be reported by itself; one of its 2 subcodes must be used instead.

Within N14, choose N14.1 (Nephropathy induced by other drugs, medicaments and biological substances) only when documentation doesn't support a more specific option: analgesic nephropathy (N14.0), nephropathy induced by unspecified drug, medicament or biological substance (N14.2), nephropathy induced by heavy metals (N14.3) and toxic nephropathy, not elsewhere classified (N14.4).

To report this condition, pick the subcode that matches the documentation: N14.11 (nephropathy) and N14.19 (substances).

Code first: poisoning due to drug or toxin, if applicable (T36-T65 with fifth or sixth character 1-4).

Use an additional code for adverse effect, if applicable, to identify drug (T36-T50 with fifth or sixth character 5).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015, and changed in FY2023 (expanded into subcodes).

Before ICD-10, this condition was coded in ICD-9-CM as 583.89 (nephritis and nephropathy, not specified as acute or chronic, with other specified pathological lesion in kidney).
