J01.31

J01.31 — Acute recurrent sphenoidal sinusitis

Billable / specific codeICD-10-CM

Excludes1 inherited from the categories above J01.31

These are not written on J01.31, but they bind it: a note on a category applies to every code beneath it. Billing J01.31 with anything listed here is a denial.

Written on J01 — Acute sinusitis

sinusitis NOS (J32.9)

Excludes2 inherited from the categories above J01.31

Also inherited, and the opposite of Excludes1: these conditions are not part of J01.31, but a patient can have both, so you may code both.

Written on J01 — Acute sinusitis

chronic sinusitis (J32.0-J32.8)

Risk adjustment

J01.31 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.

Medicare coverage

J01.31 is named in 13 Medicare coverage policies — 13 listing it as supporting medical necessity. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.
