Restrictions & Clinical Exclusions
- Crowns and indirectly fabricated restorations are considered to be an optional benefit unless the tooth is damaged by decay or fracture to the point that it cannot be restored with amalgam or resin. Benefits are denied.
- Restorative benefits are made for the least expensive professionally accepted treatment procedure (LEPAT). Any difference in the fee is denied.
- If the deciduous tooth is an “extra tooth” in addition to the normal complement of teeth, a crown is not a benefit. Benefits are denied and the approved amount is chargeable to the patient.
- If a crown is being proposed or has been done where periodontal bone support appears to be inadequate, benefits are denied due to the unfavorable prognosis for the tooth.
- Tooth preparation, temporary restorations, laboratory fees and material, cement bases, impressions, occlusal adjustment, gingivectomies (on the same date of service) and local anesthesia are considered to be included in the fee for a crown restoration. Separate fees for these procedures by the same dentist/dental office are not billable to the patient on the same date of service.
- Crowns and onlays are not a benefit for children under 12 years of age. Benefits for patient under age 12 are denied.
