Kindly note that our office does NOT handle bills/claims for uniformed firefighters and uniformed police officers and inquiries should not be made here.

Please be certain to submit all medical bills via mail to:

Workers' Compensation Service

PLEASE NOTE: bills submitted without sufficient medical documentation will not be processed.

If you are seeking authorization for an upcoming procedure please fax the request to 617-635-3119 and a response will be faxed back to you.

If you are seeking a claim number, please be advised that you do not need a claim number to submit the medical bill for payment; please submit the bill by mail to the address above with sufficient medical documentation.

Medical bill payments are generally processed within 90 days of receipt by the Medical Billing Unit, if you have recently submitted your bill please allow for 90 days prior to seeking additional information. Payments are sent out on Fridays; therefore if you believe the 90 days has just passed we ask that you wait until Wednesday to see if your payment was processed this week. If you submitted a bill more than five months ago and have yet to receive notification/payment please resubmit the bill by mail as we likely did not receive it.

If you have received notification/payment on multiple dates of service and are inquiring about a missing date of service, please resubmit the bill as we would have processed it with the other dates of service had we received it, for example physical therapy.
