10162020 PCP Fluoride Varnish Application Coding

Dear Provider,

Thank you for your continued partnership. We have some important information to share on varnish application for your patients.

Application of fluoride varnish by a primary care provider (PCP) during an EPSDT visit must be billed using CPT code 99188 and ICD-10 code Z41.8.

As a reminder, application of fluoride varnish by a PCP is reimbursed in addition to the office visit when:

  • Fluoride varnish is applied by any trained medical staff. The physician must be trained and submit attestation that all staff providing the service have been trained and will be supervised.
  • Fluoride varnish application will be combined with a risk assessment, anticipatory guidance, and referral to a dentist that treats children under the age of three (3). This will also be linked to the well child visits for children through the age of three (3).
  • These three services will be reimbursed as an all-inclusive service billed using CPT code 99188 and ICD-10 code Z41.8 and can be provided up to four (4) times a year. This frequency does not affect the frequency of this service by the dentist.
  • A bi-directional referral to the dentist is a requirement of the program, document referral in medical record. The referral process requires communication between Primary Care Providers and Primary Care Dentists. Bi-directional forms for dental referrals are available on the WellCare website at:

**Important: A referral to a dentist by one year of age or soon after the eruption of the primary tooth is mandatory. Follow up at well child visits to determine at minimum dental visits twice a year for oral evaluation and preventive services occurred and that needed treatment services are being or were provided**
