ICD-10 code for Wichman's asthma

The ICD-10-CM code for Wichman's asthma is J38.5 (Laryngeal spasm).

Within J38 (diseases of vocal cords and larynx, not elsewhere classified), J38.5 is specifically for laryngeal spasm. Related codes cover paralysis of vocal cords and larynx (J38.0), polyp of vocal cord and larynx (J38.1), Nodules of vocal cords (J38.2), other diseases of vocal cords (J38.3), edema of larynx (J38.4), stenosis of larynx (J38.6) and other diseases of larynx (J38.7).

It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.

In MS-DRG v44.0, it is part of the grouping logic for DRG 011 (Tracheostomy for Face, Mouth and Neck Diagnoses or Laryngectomy with MCC, relative weight 5.6154), DRG 012 (Tracheostomy for Face, Mouth and Neck Diagnoses or Laryngectomy with CC, relative weight 4.381), DRG 013 (Tracheostomy for Face, Mouth and Neck Diagnoses or Laryngectomy without CC/MCC, relative weight 2.7307), DRG 154 (Other Ear, Nose, Mouth and Throat Diagnoses with MCC, relative weight 1.5921), DRG 155 (Other Ear, Nose, Mouth and Throat Diagnoses with CC, relative weight 0.9322), DRG 156 (Other Ear, Nose, Mouth and Throat Diagnoses without CC/MCC, relative weight 0.6659) and 2 more, in Pre-MDC, MDC 03 (Diseases and Disorders of the Ear, Nose, Mouth and Throat) and MDC 15 (Newborns and Other Neonates with Conditions Originating in the Perinatal Period), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
