Ancillary Medical Report (EC-4 AMR)


This form is to be used to file reports for ancillary medical services such as x-ray, pathology, anesthesia, or diagnostic services by other than the attending provider in workers' compensation, volunteer firefighter's or volunteer ambulance workers' benefit cases.

All reports are to be filed with the Workers' Compensation Board, the workers' compensation insurance carrier, self-insured employer, and if the patient is represented by an attorney or licensed representative, with such representative. If the patient is not represented, a copy must be sent to the patient.

If providing treatment and performing an ancillary service, this form should not be used. Report on one of the following forms:

  • 48 HOUR INITIAL REPORT - Prepare and submit Form C-4 or EC-4NARR, complete in all details, within 48 hours after you first render treatment.
  • To report continued treatment, use Form C-4.2 or EC-4NARR. To report permanent impairment, use Form C-4.3.
