ICD-10 Code for Croup
Also indexed as (catarrhal) (infectious) (inflammatory) (nondiphtheritic)
The ICD-10-CM code for croup is J05.0 — Acute obstructive laryngitis [croup]. This is the code the Alphabetic Index gives for croup with no further qualifier, valid for FY2027 (October 1, 2026 – September 30, 2027).
Which croup code should you use?
The Alphabetic Index lists 4 codes under Croup, croupous. Which one applies depends on the qualifier documented in the record — the type, site, cause, or associated condition. Find the qualifier below, then verify the code in the Tabular List before using it.

| diphtheritic | A36.2 | Laryngeal diphtheria |
Croup stridulous
| diphtheritic | A36.2 | Laryngeal diphtheria |
