Can I send Medical Records with Electronic Claims
PWK Segment for sending information for electronic claims
Electronic medical records cannot be attached to an electronic claim. These instructions will show how to input the PWK segment in a claim to indicate Medical reports or any attachments are being forwarded by fax or mail to the payer.
- Within the visit information indicate the following in the Box 19 field: PWK*M1*BM (This indicates Medical Record Attachment is being mailed)

- Attached is a listing of all the codes that will be listed in the first field after PWK* (the asterisk needs to be after each code as shown above in the example)
- The second code will indicate if the attachments are mailed or faxed:
- BM (By Mail)
- FX (Faxed)
Do not place an asterisk after this code.
The ACN number is the patient's account number and visit number combined which is programmed in the electronic claims module, this is not required to be indicated in Box 19 of the visit screen.
