Doctor's Narrative Report (EC-4NARR) Overview/Features

Doctor's Narrative Report - (EC-4NARR)

It is anticipated that all versions of the C-4 medical billing forms (except the C-4.3) will be replaced by the required XML submission of the CMS-1500 form on or about July 1, 2021. Learn more about the CMS-1500 Initiative.


The Doctor's Narrative Report (EC-4NARR) is a new form the Board is providing to health care providers to assist with filing medical reports with the NYS Workers' Compensation Board.

The EC-4NARR form will only be accepted by the Board through electronic submission. Every EC-4NARR filed with the Board is electronically signed by a Board authorized health care provider in compliance with the New York State Electronic Signatures and Records Act (ESRA) and its accompanying regulation (9 NYCRR 540).

To report permanent impairment, submit form Doctor's Report of MMI/Permanent Impairment (C-4.3).

To request authorization for special services costing over $1000.00, submit form Attending Doctor's Request for Authorization and Carrier's Response (C-4AUTH).


Instead of filing the Doctor's Initial Report (C-4) and Doctor's Progress Report (C-4.2) forms, health care providers may file the Doctor's Narrative Report (EC-4NARR) to report both the initial and continued treatment, however, a narrative attachment must be included with the form which provides all the additional information which otherwise would be provided on the other forms. Please read "Attachment Requirements".

You asked and we listened… Over the years, the Board has had many requests from health care providers to be able to save doctor/patient/carrier information to be used to submit subsequent progress reports to the Board. The new web submission form will provide this desired feature.

XML Batch Submissions

The Board has an established program to receive electronic forms in a XML batch submission format. For more information on this program please refer to our Overview page (
