2018 CDT Code Revisions

The 2018 Dental Code changes went into effect January 1, 2018 and include:

  • 18 new codes
  • 3 deleted codes
  • 16 revised codes

Updating your system annually with code revisions:

  • Helps clarify treatment for team members, patients and third party payers
  • Pprovides accurate estimates for your patient base
  • Enables proper reimbursement from third-party payers

It is important to remember a new or revised code does not dictate reimbursement from insurance providers. In fact, codes may be recognized but not reimbursed at all. Consider it a language of sorts that providers and insurance companies understand; it helps communicate the services provided in numerical terms.

Most carriers notified in-network providers as to their requirements and reimbursement protocols prior to the end of 2017. We encourage you to follow a two part protocol annually:

  • Reach out to insurance companies you deal with on a regular basis to prepare for changes that occur to CDT definitions on January 1 of each year.
  • Facilitate a team meeting to discuss CDT changes and how their impact may shift chart note records, posting and patient communication for the procedures you offer.

Reach out to your Burkhart Account Manager or Burkhart’s Practice Support Team with your questions regarding changes in codes, coding strategies to maximize reimbursement, and analyzing managed care participation in your practice.
