Background House Bill No. 303, as amended by House Amendment No. 2, of the 151st General Assembly (“HB 303”), signed by the Governor on August 3, 2022, added new sections 3370E and 3571Z to the Delaware Insurance Code (18 Del.C. §§ 101, et seq.). Both new sections are identical and require carriers to provide coverage for an annual behavioral health well check. HB 303 also created an advisory committee tasked with developing recommendations for implementing the Act. On December 9, 2022, the advisory committee voted to approve the Guidelines for Administering an Annual Behavioral Health Well Check, fulfilling its statutory mandate0F1. Specifics of Annual Behavioral Health Well Check Coverage HB 303 lists the CPT codes under which providers must be reimbursed. Additionally, carriers are required to reimburse providers at the same rate that such CPT codes are reimbursed for the provision of other medical care, provided that reimbursement may be adjusted for payment of claims that are billed by a nonphysician clinician so long as the methodology to determine such adjustments is comparable to and applied no more stringently than the methodology for adjustments made for reimbursement of claims billed by nonphysician clinicians for other medical care, in accordance with 45 CFR 146.136(c)(4). 1 See House Bill 303 Behavioral Health Well Check Advisory Committee Final Report, Delaware Department of Health and Social Services (Dec. 9, 2022). 26 Note: This Bulletin is intended solely for informational purposes.
