Indiana Code Title 27. Insurance § 27-7-2-31

Sec. 31. No employer who does not pay the advance premiums or premium when due, shall be entitled to insurance, nor shall any coverage be extended until all obligations to pay worker's compensation insurance premiums contracted during the previous twelve (12) months have been paid.  If, in the opinion of the designated carrying company or the bureau, physical or moral conditions exist in any risk which shall preclude the risk from obtaining insurance, that risk shall be reported to the worker's compensation board and to the department.  The bureau shall, in those cases, furnish the board and the department with its recommendations for improving safety conditions, which, if complied with, would entitle the risk to insurance.  Pending a decision by the board or the department, insurance shall be effective as otherwise provided in this chapter.  However, the board, or the department, or both shall make that decision within sixty (60) days after such recommendations are furnished by the bureau.
