N14.1 — Nephropathy induced by other drugs, medicaments and biological substances
Is N14.1 billable?
No — N14.1 is a non-billable header code. N14.1 groups more specific codes and cannot be submitted on a claim. A valid ICD-10-CM code must be reported at the highest level of specificity available in its branch. Select one of the 2 billable codes beneath N14.1.

Excludes1 — never code together — inherited from N10-N16
The conditions below can never be reported together with N14.1 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.
- pyeloureteritis cystica (N28.85)
Code first — inherited from N14
The underlying condition below must be sequenced before N14.1. N14.1 describes a manifestation and cannot be the principal or first-listed diagnosis.
- poisoning due to drug or toxin, if applicable (T36-T65 with fifth or sixth character 1-4)
Use additional code — inherited from N14
Report an additional code alongside N14.1 to fully describe the condition. N14.1 is sequenced first.
- code for adverse effect, if applicable, to identify drug (T36-T50 with fifth or sixth character 5)
Excludes2 — not included here — inherited from Chapter 14
The conditions below are not part of N14.1, but a patient may have both at the same time. When documentation supports it, N14.1 and the excluded code may both be reported.
- certain conditions originating in the perinatal period (P04-P96)
- certain infectious and parasitic diseases (A00-B99)
- complications of pregnancy, childbirth and the puerperium (O00-O9A)
- congenital malformations, deformations and chromosomal abnormalities (Q00-Q99)
- endocrine, nutritional and metabolic diseases (E00-E88)
- injury, poisoning and certain other consequences of external causes (S00-T88)
