Varicella [chickenpox]

Not billableICD-10-CM diagnosis code.

This code exists but cannot be submitted on its own. It groups the more specific codes beneath it.

A category header for its whole life, FY2016 onwards. It has never been valid for submission on its own.

Submit one of these 5 more specific codes instead:

  • B01.0 Varicella meningitis
  • B01.1 Varicella encephalitis, myelitis and encephalomyelitis (also a header)
  • B01.2 Varicella pneumonia
  • B01.8 Varicella with other complications (also a header)
  • B01.9 Varicella without complication

What has happened to this code

Every change the publisher made, from 2012 to now. Entries marked draft are from the pre-implementation releases: ICD-10 took effect on 1 October 2015, so nothing before FY2016 was ever valid on a claim.
