J98.8 — Other specified respiratory disorders
Is J98.8 billable?
Yes, but J98.8 is an unspecified code. J98.8 is a valid, billable ICD-10-CM code for encounters from October 1, 2026 through September 30, 2027. However, J98.8 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 J98.8 — the more specific alternatives are listed below.

Excludes1 — never code together — inherited from J98
The conditions below can never be reported together with J98.8 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 J98.8 to fully describe the condition. J98.8 is sequenced first.
