Section 1797 - Customary charges for treatment(a) General rule.-- A person or institution providing treatment, accommodations, products or services to an injured person for an injury covered by liability or uninsured and underinsured benefits or first party medical benefits, including extraordinary medical benefits, for a motor vehicle described in Subchapter B (relating to motor vehicle liability insurance first party benefits) shall not require, request or accept payment for the treatment, accommodations, products or services in excess of 110% of the prevailing charge at the 75th percentile; 110% of the applicable fee schedule, the recommended fee or the inflation index charge; or 110% of the diagnostic-related groups (DRG) payment; whichever pertains to the specialty service involved, determined to be applicable in this Commonwealth under the Medicare program for comparable services at the time the services were rendered, or the provider's usual and customary charge, whichever is less. The General Assembly finds that the reimbursement allowances applicable in the Commonwealth under the Medicare program are an appropriate basis to calculate payment for treatments, accommodations, products or services for injuries covered by liability or uninsured and underinsured benefits or first party medical benefits insurance. Future changes or additions to Medicare allowances are applicable under this section. If the commissioner determines that an allowance under the Medicare program is not reasonable, he may adopt a different allowance by regulation, which allowance shall be applied against the percentage limitation in this subsection. If a prevailing charge, fee schedule, recommended fee, inflation index charge or DRG payment has not been calculated under the Medicare program for a particular treatment, accommodation, product or service, the amount of the payment may not exceed 80% of the provider's usual and customary charge. If acute care is provided in an acute care facility to a patient with an immediately life-threatening or urgent injury by a Level I or Level II trauma center accredited by the Pennsylvania Trauma Systems Foundation under theact of July 3, 1985 (P.L. 164, No. 45) , known as the Emergency Medical Services Act, or to a major burn injury patient by a burn facility which meets all the service standards of the American Burn Association, the amount of payment may not exceed the usual and customary charge. Providers subject to this section may not bill the insured directly but must bill the insurer for a determination of the amount payable. The provider shall not bill or otherwise attempt to collect from the insured the difference between the provider's full charge and the amount paid by the insurer.(b) Peer review plan for challenges to reasonableness and necessity of treatment.--(1) Peer review plan.--Insurers shall contract jointly or separately with any peer review organization established for the purpose of evaluating treatment, health care services, products or accommodations provided to any injured person. Such evaluation shall be for the purpose of confirming that such treatment, products, services or accommodations conform to the professional standards of performance and are medically necessary. An insurer's challenge must be made to a PRO within 90 days of the insurer's receipt of the provider's bill for treatment or services or may be made at any time for continuing treatment or services.(2) PRO reconsideration.--An insurer, provider or insured may request a reconsideration by the PRO of the PRO's initial determination. Such a request for reconsideration must be made within 30 days of the PRO's initial determination. If reconsideration is requested for the services of a physician or other licensed health care professional, then the reviewing individual must be, or the reviewing panel must include, an individual in the same specialty as the individual subject to review.(3) Pending determinations by PRO.--If the insurer challenges within 30 days of receipt of a bill for medical treatment or rehabilitative services, the insurer need not pay the provider subject to the challenge until a determination has been made by the PRO. The insured may not be billed for any treatment, accommodations, products or services during the peer review process.(4) Appeal to court.--A provider of medical treatment or rehabilitative services or merchandise or an insured may challenge before a court an insurer's refusal to pay for past or future medical treatment or rehabilitative services or merchandise, the reasonableness or necessity of which the insurer has not challenged before a PRO. Conduct considered to be wanton shall be subject to a payment of treble damages to the injured party.(5) PRO determination in favor of provider or insured.--If a PRO determines that medical treatment or rehabilitative services or merchandise were medically necessary, the insurer must pay to the provider the outstanding amount plus interest at 12% per year on any amount withheld by the insurer pending PRO review.(6) Court determination in favor of provider or insured.--If, pursuant to paragraph (4), a court determines that medical treatment or rehabilitative services or merchandise were medically necessary, the insurer must pay to the provider the outstanding amount plus interest at 12%, as well as the costs of the challenge and all attorney fees.(7) Determination in favor of insurer.--If it is determined by a PRO or court that a provider has provided unnecessary medical treatment or rehabilitative services or merchandise or that future provision of such treatment, services or merchandise will be unnecessary, or both, the provider may not collect payment for the medically unnecessary treatment, services or merchandise. If the provider has collected such payment, it must return the amount paid plus interest at 12% per year within 30 days. In no case does the failure of the provider to return the payment obligate the insured to assume responsibility for payment for the treatment, services or merchandise.(c) Review authorized.--By December 1, 1991, the Legislative Budget and Finance Committee shall commence a review of the impact of this section. Such review may be conducted biennially. 1984, Feb. 12, P.L. 53, No. 12, § 3, effective 10/1/1984. Amended 1990, Feb. 7, P.L. 11, No. 6, § 18, effective 4/15/1990.
