H81.8X9 — Other disorders of vestibular function, unspecified ear
Is H81.8X9 billable?
Yes, but H81.8X9 is an unspecified code. H81.8X9 is a valid, billable ICD-10-CM code for encounters from October 1, 2026 through September 30, 2027. However, H81.8X9 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 H81.8X9 — the more specific alternatives are listed below.

Excludes1 — never code together — inherited from H81
The conditions below can never be reported together with H81.8X9 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 8
The conditions below are not part of H81.8X9, but a patient may have both at the same time. When documentation supports it, H81.8X9 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)
