In the Bluebook, for Cleanings (D1110/D1120), under limitations, we should be able to set how often cleanings are covered.
- Once every 6 months/180 days
- 2 times per year
- Once every 12 months/365 days
- Once per calendar year
This could also be helpful for exams (D0120) or X-rays (D0210, D0274, etc.)
- Once per year
- Once every 5 years
