ICD-10 code for larynx cellulitis

The ICD-10-CM code for larynx cellulitis is J38.7 (Other diseases of larynx).

Within J38, choose J38.7 (Other diseases of larynx) only when documentation doesn't support a more specific option: 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 stenosis of larynx (J38.6).

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.
