The notice shall include specific reasons supporting the contest or denial, a description of any additional information needed by the employer or insurance carrier to determine liability for the medical bill, and a request that such information be submitted to the employer or insurance carrier within 30 days following receipt of the notice.(b) Disputes regarding payment of a medical bill may be filed with the Commissioner by the injured employee or the health care provider. Disputes regarding payment of a medical bill or interest on that bill shall be determined by the Commissioner or, at the option of either party, be settled by arbitration in accordance with the Commercial Rules of the American Arbitration Association. The decision of an arbitrator shall be provided to the Commissioner, and the award may be entered as a judgment in a court of jurisdiction.(c) If a medical bill was denied on the basis that the employer or insurance carrier was not provided with sufficient information to determine liability for payment pursuant to subdivision (a)(2) of this section, the employer or insurance carrier has 30 days following receipt of the additional information requested to pay or deny payment of the bill.(d) Medical bills shall be paid within the time required in this section or according to the time requirements specified in a contract between the health care provider and the employer or insurance carrier.(e) Interest shall accrue on an unpaid medical bill at the rate of 12 percent per annum calculated as follows:(1) From the first calendar day following 30 days after the date the medical bill is received by the employer or insurance carrier for : (A) a medical bill that was not denied; or(B) a medical bill that was denied and written notice was not provided or not provided within 30 days after receipt of the medical bill.

The Commissioner may extend the six-month limit if the Commissioner determines that the delay resulted from circumstances outside the control of the health care provider. (g) A medical bill shall be submitted in a legible form with every field or data element relevant to the treatment completed and treatment coding that conforms to the criteria of the National Correct Coding Initiative.

The notice must include:(A) the injured employee's name;(D) the proposed adjustment; and(E) a reasonably specific explanation of the proposed adjustment.(2) The time that has elapsed does not exceed 12 months from the later of the date of payment of the previously paid medical bill or the date of a final determination of compensability.(k) The retrospective denial of a previously paid medical bill shall be permitted beyond 12 months from the later of the date of payment or the date of a final determination of compensability for any of the following reasons: (1) The employer or insurance carrier has a reasonable belief that fraud or other intentional misconduct has occurred.(2) The medical bill payment was incorrect because the health care provider was already paid for the health services identified in the medical bill.(3) The health care services identified in the medical bill were not delivered by the health care provider.(4) The medical bill payment is the subject of adjustment with another workers' compensation or health insurer.(5) The medical bill is the subject of legal action.(l)(1) For purposes of subsections (j) and (k) of this section, for routine recoveries as described in subdivisions (A) through (J) of this subdivision (1), retrospective denial or overpayment recovery of any or all of a previously paid medical bill shall not require 30 days' notice before recovery may be made. A recovery shall be considered routine only if one of the following situations applies: (A) duplicate payment to a health care provider for the same professional service;(B) payment with respect to an individual for whom the employer or insurance carrier is not liable as of the date the service was provided;(C) payment for a noncovered service, not to include services denied as not medically necessary, experimental, or investigational in nature, or services denied through a utilization review mechanism;(D) erroneous payment for services due to employer or insurance carrier administrative error;(E) erroneous payment for services where the medical bill was processed in a manner inconsistent with the data submitted by the health care provider;(F) payment where the health care provider provides the employer or insurance carrier with new or additional information demonstrating an overpayment;(G) payment to a health care provider at an incorrect rate or using an incorrect fee schedule;(H) payment of medical bills for the same injured employee that are received by the employer or insurance carrier out of the chronological order in which the services were performed;(I) payment where the health care provider has received payment for the same services from another payer whose obligation is primary; or(J) payments made in coordination with a payment by a government payer that require adjustment based on an adjustment in the government-paid portion of the medical bill.(2) Notwithstanding the provisions of subdivision (1) of this subsection, recoveries which, in the reasonable business judgment of the employer or insurance carrier, would be likely to affect a significant volume of claims or accumulate to a significant dollar amount shall not be deemed routine, regardless of whether one or more of the situations in subdivisions (1)(A) through (J) of this subsection apply.(3) Nothing in this subsection shall be construed to affect the time frames established in subdivision (j)(2) or subsection (k) of this section.Amended by 2024 , No. 85, § 129, eff. 7/1/2024.Added 2009 , No. 61, § 27; amended 2011, No. 78 (Adj.
