K13.2: Leukoplakia and other disturbances of oral epithelium, including tongue

Non-billable headerICD-10-CM

K13.2 is a non-billable header ICD-10-CM code for leukoplakia and other disturbances of oral epithelium, including tongue. It cannot be billed on its own: choose one of the more specific child codes below.

Excludes1: never code together

These conditions cannot occur together. Billing both on the same encounter is a denial.

  • carcinoma in situ of oral epithelium (D00.0-)
  • hairy leukoplakia (K13.3)

Excludes2 inherited from the categories above K13.2

Not part of this code, but both may be coded when both are present.

Written on K13: Other diseases of lip and oral mucosa

  • certain disorders of gingiva and edentulous alveolar ridge (K05-K06)
  • cysts of oral region (K09.-)
  • diseases of tongue (K14.-)
  • stomatitis and related lesions (K12.-)

Other codes that can never be billed with K13.2

Their own Excludes1 notes name this code, so the conflict is not listed above.
