Minn. Stat. § 62Q.75
Subd. 1. Definitions.
Subd. 2. Claims payments.
Subd. 3. Claims filing.
Unless otherwise provided by contract, by section 16A.124, subdivision 4a, or by federal law, the health care providers and facilities specified in subdivision 2 must submit their charges to a health plan company or third-party administrator within six months from the date of service or the date the health care provider knew or was informed of the correct name and address of the responsible health plan company or third-party administrator, whichever is later. A health care provider or facility that does not make an initial submission of charges within the six-month period shall not be reimbursed for the charge and may not collect the charge from the recipient of the service or any other payer. The six-month submission requirement may be extended to 12 months in cases where a health care provider or facility specified in subdivision 2 has determined and can substantiate that it has experienced a significant disruption to normal operations that materially affects the ability to conduct business in a normal manner and to submit claims on a timely basis. This subdivision also applies to all health care providers and facilities that submit charges to workers' compensation payers for treatment of a workers' compensation injury compensable under chapter 176, or to reparation obligors for treatment of an injury compensable under chapter 65B.
