Your question is really more specific to your PM software and your practice's procedures. Personally, if I go on a web portal and find out about a payment (as a billing service) I have a procedure for how I handle it. I enter the payment into my PM Software and note that the payment info came "per web" and note the ck#, date paid, etc. Then I also notify the provider's office that I didn't get that eob. They may have gotten it but inadvertently didn't forward it to me. The web usually will give the contractual adjustment, patient responsibility, etc, so I enter all info.
