A study by the National Council of Compensation Insurance (NCCI) confirms what experienced workers’ compensation experts have been saying for years -- delayed reporting of workers’ comp claims will cost you. Specifically, the report said that the late reporting of claims: 1) costs employers more in dollars, increasing the loss ratio of business entities, 2) increases their experience modifications, and 3) ultimately has a negative effect on workers compensation premiums, regardless of the insuring company.
