J01.1 — Acute frontal sinusitis
J01.1 is a non-billable header ICD-10-CM code for acute frontal sinusitis. It cannot be billed on its own: choose one of the more specific child codes below.
Excludes1 inherited from the categories above J01.1
These are not written on J01.1, but they bind it: a note on a category applies to every code beneath it. Billing J01.1 with anything listed here is a denial.
Excludes2 inherited from the categories above J01.1
Also inherited, and the opposite of Excludes1: these conditions are not part of J01.1, but a patient can have both, so you may code both.
Risk adjustment
J01.1 does not map to an HCC and does not risk-adjust under CMS-HCC V28. That is normal — most ICD-10 codes do not. It still needs to be coded correctly; it just will not move a RAF score.
Code history
J01.1 has not changed since FY2024 — no addition, revision or deletion across the three most recent ICD-10-CM releases.

Questions about J01.1
- Is J01.1 a billable ICD-10-CM code?
- No. J01.1 is a non-billable header code. Code to a higher level of specificity using one of its child codes.
- Where does J01.1 sit in the tabular list?
- Diseases of the respiratory system (J00-J99), in the block Acute upper respiratory infections (J00-J06).
- What cannot be coded together with J01.1?
- J01.1 carries Excludes1 notes, which means the conditions they list can never be coded together with it on the same encounter. Some are written on the categories above J01.1 (J01) and apply to it just the same.
