Good Evening all.

I have received my first few 835 response files through office Ally and I’m trying to read them into OpenEMR with mixed result.

One problem I see is that the payer\_id is not being identified. The value is not showing up in TRN04 in any of the 835 files I have and it appears this is the only way that OpenEMR recognizes the payer.

Anyone else see this problem and have a solution?

Thanks,  
Kyle

I was specifically looking at the ar\_session table which does not have the payer\_id.

Apparently somewhere down stream it can correlate as the invoice shows the correct payer… is payer\_id in ar\_session still used?

hi @KyleNave, payer id can have different contexts, the most common which you’re probably familiar with is the electronic payer id which helps route claims to the correct payers through clearinghouses. `TRN04` is seldom used and maybe only in institutional cases.

In this case the payer id in `ar_session` is the openemr payer id from the `insurance_data` table which is sourced from `insurance_companies.id` but this might not be used in the era posting routine.
