So I did my name change 3½ years ago and everything was updated. My health insurance through Horizon Blue Cross Blue Shield of NJ was also updated, but it took them almost a year to propagate through their who computer system or so I thought. I have had numerous claims filled by my health providers and covered including GCS I had this past November. They have paid the claims submitted electronically and everything has shown the correct name for the last 2½ years or more.
I had genital electrolysis last Spring/Summer that is covered by my insurance policy. However, you have to pay out of pocket first and then get reimbursed, but you have to wait until the insurance approved my GCS which they did 3 weeks before my surgery and it was recommended to wait until they paid at least one of the hospital bills from GCS as it required special approval and I could reference the approval number on the claim form.
So after they paid my surgeon and hospital, I filed manually with a form I printed online and submitted my claim with a copy of the invoices with the CPT codes and all. Everything had the correct name. This morning I received an E-MAIL about a new EOB on my account and looked it up and my
deadname was all over the place with the correct subscriber ID on the EOB. Now I know my subscriber ID stayed is the same as before my name change, but obviously, when someone keyed it in, my deadname must have been in there and the person didnt't really read or l look at the invoices or form. Are people that lazy?

? So it was denied with the code:
QuoteE280 - THIS CLAIM IS NOT PAID. THE PATIENT'S NAME SUBMITTED ON THIS CLAIM COULD NOT BE IDENTIFIED ON THE SUBSCRIBER'S HEALTH BENEFIT PLAN.
Wow, really?? You think??
So I call up BCBS and the customer service rep did not see my deadname anywhere in the system as she was confused as to where the name came from. She was completely stumped. So she told me to resubmit it and in the place in the form where it says "Name of Patient - (If Patient is the same as the Insured, please skip)" to go ahead and put my name there too even though I shouldn't have to.
So this is why you document and keep copies.
