J30.9 — Allergic rhinitis, unspecified
Is J30.9 billable?
Yes, but J30.9 is an unspecified code. J30.9 is a valid, billable ICD-10-CM code for encounters from October 1, 2026 through September 30, 2027. However, J30.9 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 J30.9 — the more specific alternatives are listed below.

Excludes1 — never code together — inherited from J30
The conditions below can never be reported together with J30.9 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.
Use additional code — inherited from Chapter 10
Report an additional code alongside J30.9 to fully describe the condition. J30.9 is sequenced first.
Excludes2 — not included here — inherited from Chapter 10

- certain infectious and parasitic diseases (A00-B99)
- complications of pregnancy, childbirth and the puerperium (O00-O9A)
- congenital malformations, deformations and chromosomal abnormalities (Q00-Q99)
