Other diseases of lip and oral mucosa

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 8 more specific codes instead:

  • K13.0 Diseases of lips
  • K13.1 Cheek and lip biting
  • K13.2 Leukoplakia and other disturbances of oral epithelium, including tongue (also a header)
  • K13.3 Hairy leukoplakia
  • K13.4 Granuloma and granuloma-like lesions of oral mucosa
  • K13.5 Oral submucous fibrosis
  • K13.6 Irritative hyperplasia of oral mucosa
  • K13.7 Other and unspecified lesions of oral mucosa (also a header)

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.
