(f)

1. (1) Except as provided in paragraph (2), the department shall require pretreatment radiograph documentation on posttreatment claims to establish the medical necessity for dental restorations. The pretreatment documentation required under this subdivision is intended to reduce fraudulent claims for unnecessary dental fillings. In order to avoid any undue barriers to accessing dental care, the department shall stipulate that the pretreatment radiograph documentation for posttreatment claims will be required only when there are four or more dental fillings being completed in any 12-month period.
2. (2) For any beneficiary who is under four years of age, or who, regardless of age, has a developmental disability, as defined in subdivision (a) of Section 4512, radiographs or photographs that indicate decay on any tooth surface shall be considered sufficient documentation to establish the medical necessity for treatment provided.
3. (3) Notwithstanding Chapter 3.5 (commencing with Section 11340) of Part 1 of Division 3 of Title 2 of the Government Code, the department may implement, interpret, or make specific this section, in whole or in part, by means of provider bulletins, plan letters, or other similar instructions, without taking regulatory action.
