90- 351 C.M.R. ch. 8, § 1
The initial Statement of Compensation Paid, Interim Report (WCB-11) shall be filed with the Board within 195 days of the date of an injury where indemnity payments have been made, and as a Final Report when no further payments are anticipated. Subsequent Statements of Compensation Paid (WCB-11) shall thereafter be filed with the Board within fifteen (15) days of each anniversary date of an injury when payments of any type have been made since the previous Statement of Compensation Paid (WCB-11). The Statement of Compensation Paid (WCB-11) is required when only medical payments are made subsequent to the filing of a Final Report. There is no requirement to file the Statement of Compensation Paid on claims when payments are made for medical only services and no indemnity was ever paid on the claim.
