I submitted a claim to Cigna Healthcare on a paper CMS-1500. Line 1 is a date range of 5/1/14-5/6/14, per diem HCPC, 6 units. Line 2 is a date range of 5/7/14-5/12/14, per diem HCPC, 6 units. They paid the claim and I have no issue with what they paid, however, there is further reimbursement possible at a secondary payer, and how they listed the service dates is insufficient to send to the secondary. The problem is they only list a single "procedure date" for each line on the eob, so line 1 looks like only one day, "5/1/14," and line 2 only looks like one day, "5/7/14." Number of units isn't listed anywhere either, so it looks like they paid a very large amount for one day of service.
They will not do anything to correct or clarify the EOB, stating their internal system shows the full date range and that is just how their EOB's print. I have a call in to Cigna Provider Relations and am prepared to file a complaint with the TN insurance commission, but want to know if a regulation exists I can reference mandating an EOB reflect the exact dates given on a 1500? If CMS allows for a from and a to, one would think EOB's must reflect that as well.
