Our medical biller has been working from home for the past five years with, what turns out to be, a faulty VPN. Because this person never checked on claims (person is the practice manager in a small office), hundreds of claims, possibly for two years, never got filed. Or were rejected for various reasons and the biller just went in and marked "negative adjustment" in the ledger for the entire amount. How can we, or can we, get these claims paid? We went back to January 2014 and rebilled JAN-JULY 2014 at the end of September. The first batch of denials are coming in. What recourse can we take? I am the physician's wife, newly retired from public education, currently enrolled in the online medical billing course. We need help now that is beyond my level of understanding. Thank you in advance for any help.
