N92.5 — Other specified irregular menstruation
Is N92.5 billable?
Yes, but N92.5 is an unspecified code. N92.5 is a valid, billable ICD-10-CM code for encounters from October 1, 2026 through September 30, 2027. However, N92.5 is an unspecified or catch-all code. Payers apply additional scrutiny to unspecified codes and many deny them when the medical record supports a more specific option, so check the documentation before selecting N92.5 — the more specific alternatives are listed below.

Excludes1 — never code together — inherited from N92
The conditions below can never be reported together with N92.5 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.
Excludes2 — not included here — inherited from Chapter 14
The conditions below are not part of N92.5, but a patient may have both at the same time. When documentation supports it, N92.5 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 N92.5 existed?
