About coding larynx mucous polyp
The ICD-10-CM code for larynx mucous polyp is J38.1 (Polyp of vocal cord and larynx). The official index lists 1 more specific code, so check the documentation for details such as type, cause, site or severity before settling on J38.1.
Within J38 (diseases of vocal cords and larynx, not elsewhere classified), J38.1 is specifically for polyp of vocal cord and larynx. Related codes cover paralysis of vocal cords and larynx (J38.0), Nodules of vocal cords (J38.2), other diseases of vocal cords (J38.3), edema of larynx (J38.4), laryngeal spasm (J38.5), stenosis of larynx (J38.6) and other diseases of larynx (J38.7).
Don't report J38.1 together with the conditions in its Excludes1 note: adenomatous polyps (D14.1).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
