J04.3 — Supraglottitis, unspecified

Non-billable headerICD-10-CM

Excludes1 inherited from the categories above J04.3

These are not written on J04.3, but they bind it: a note on a category applies to every code beneath it. Billing J04.3 with anything listed here is a denial.

Written on J04 — Acute laryngitis and tracheitis

acute obstructive laryngitis [croup] and epiglottitis (J05.-)

Excludes2 inherited from the categories above J04.3

Also inherited, and the opposite of Excludes1: these conditions are not part of J04.3, but a patient can have both, so you may code both.

Written on J04 — Acute laryngitis and tracheitis

laryngismus (stridulus) (J38.5)

Risk adjustment

J04.3 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

J04.3 has not changed since FY2024 — no addition, revision or deletion across the three most recent ICD-10-CM releases.
