William Maybe I'm missing something here but anytime the prime pays a service line in full there is nothing more to be done with that line by any subsequent payer, no? When your company received the claim transaction that service line would look something like this:
SV2*REV*HC:proc*100*UN*1~ (the original service line with a charge of $100) SVD*Medicare ID*100*HC:proc*REV*1~ (this shows the service line paid in full by Medicare) there are no CAS segments to this line as it was paid in full. Now, when you send out the 835 transaction you cannot make any further adjustments on this line regardless of your policies because it has already been paid in full. Therefore, your correct adjustment code on your 835 would be that another payer has paid this amount previously (code 23, commonly used in secondary 835s). The CAS segment is used to report adjustments to a line/claim, explaining why a claim/line was paid differently than it was billed. In this case there can be no further adjustments to this line as it has been paid in full. Your 835 would look like: SVC*HC:proc*100*0**0**1~ CAS*OA*23*100~ Hope this helps.
