ICD-10 code for larynx constriction

The ICD-10-CM code for larynx constriction is J38.6 (Stenosis of larynx). The official index lists 3 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on J38.6.

Within J38 (diseases of vocal cords and larynx, not elsewhere classified), J38.6 is specifically for stenosis of larynx. 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), laryngeal spasm (J38.5) 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) and DRG 156 (Other Ear, Nose, Mouth and Throat Diagnoses without CC/MCC, relative weight 0.6659), in Pre-MDC and MDC 03 (Diseases and Disorders of the Ear, Nose, Mouth and Throat), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
