Section 716(a) of Title 24 prohibits annual or lifetime numerical limits on chiropractic visits for the treatment of back pain. The treatment of chronic back pain through chiropractic supportive care can prevent patients from requiring opioid pain medications or more expensive treatments. This Act prohibits the denial of insurance coverage under § 716(a) for chiropractic supportive care, which constitutes maintenance therapy. This requirement applies to policies, contracts, or certificates issued, renewed, modified, altered, amended, or reissued after December 31, 2023. In addition, this Act clarifies, but does not expand, the insurance coverage subject to the requirements under § 716(a), states that the requirements under this subsection cannot be waived by contract, and requires that the regulations implementing § 176 establish utilization review standards. This Act also updates the definitions in Chapter 7 of Title 24 to be consistent with the current scope of chiropractic practice and makes corresponding revisions to the terms used in existing law. This Act also makes technical corrections to conform existing law to the standards of the Delaware Legislative Drafting Manual.
