Yes, once your work injury is accepted and/or memorialized as entitling you to workers’ compensation benefits, you will receive benefits retroactive to your first date of disability, minus any amounts you may have received in TDI or other wages.  

Keep in mind, however, that there is a statute of limitaitons in Rhode Island that provides you must file your case no later than two (2) years from the date of injury. If your date of injury and first date of lost time are different, consult with a lawyer regarding any questions you have regarding the statute of limitations.
