ICD-10 code for Herpangina

The ICD-10-CM code for Herpangina is B08.5 (Enteroviral vesicular pharyngitis).

Within B08 (other viral infections characterized by skin and mucous membrane lesions, not elsewhere classified), B08.5 is specifically for enteroviral vesicular pharyngitis. Related codes cover other orthopoxvirus infections (B08.0), Molluscum contagiosum (B08.1), exanthema subitum [sixth disease] (B08.2), erythema infectiosum [fifth disease] (B08.3), enteroviral vesicular stomatitis with exanthem (B08.4), parapoxvirus infections (B08.6), yatapoxvirus infections (B08.7) and other specified viral infections characterized by skin and mucous membrane lesions (B08.8).

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 152 (Otitis Media and URI with MCC, relative weight 1.1151) and DRG 153 (Otitis Media and URI without MCC, relative weight 0.7421), 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.
