Indiana Code Title 22. Labor and Safety § 22-3-3-5

Sec. 5. (a) The pecuniary liability of the employer for a service or product herein required shall be limited to the following:

(b) The employee and the employee's estate do not have liability to a health care provider for payment for services obtained under IC 22-3-3-4.

(c) The right to order payment for all services or products provided under IC 22-3-2 through IC 22-3-6 is solely with the board.

(d) All claims by a medical service provider for payment for services or products are against the employer and the employer's insurance carrier, if any, and must be made with the board under IC 22-3-2 through IC 22-3-6. After June 30, 2011, a medical service provider must file an application for adjustment of a claim for a medical service provider's fee with the board not later than two (2) years after the receipt of an initial written communication from the employer, the employer's insurance carrier, if any, or an agent acting on behalf of the employer after the medical service provider submits a bill for services or products. To offset a part of the board's expenses related to the administration of medical service provider reimbursement disputes, a medical service facility shall pay a filing fee of sixty dollars ($60) in a balance billing case. The filing fee must accompany each application filed with the board. If an employer, an employer's insurance carrier, or an agent acting on behalf of the employer denies or fails to pay any amount on a claim submitted by a medical service facility, a filing fee is not required to accompany an application that is filed for the denied or unpaid claim. A medical service provider may combine up to ten (10) individual claims into one (1) application whenever:

(e) The worker's compensation board may withhold the approval of the fees of the attending physician in a case until the attending physician files a report with the worker's compensation board on the form prescribed by the board.
