N14 — Drug- and heavy-metal-induced tubulo-interstitial and tubular conditions
Is N14 billable?
No — N14 is a non-billable header code. N14 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 6 billable codes beneath N14.

Code first
The underlying condition below must be sequenced before N14. N14 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
Report an additional code alongside N14 to fully describe the condition. N14 is sequenced first.
- code for adverse effect, if applicable, to identify drug (T36-T50 with fifth or sixth character 5)
Excludes1 — never code together — inherited from N10-N16
The conditions below can never be reported together with N14 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)
Excludes2 — not included here — inherited from Chapter 14
The conditions below are not part of N14, but a patient may have both at the same time. When documentation supports it, N14 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)
- neoplasms (C00-D49)
- symptoms, signs and abnormal clinical and laboratory findings, not elsewhere classified (R00-R94)

How long has N14 existed?
N14 has been in ICD-10-CM since at least FY2016, the earliest fiscal year on record here.
Derived from the official order files for FY2016–FY2026. FY2017 and FY2020 publish no order file, so those years are not covered.
