statute of Limitation

A physician suddenly took over an existing practice last June and officially bought the business in September. Physician hasn't billed anything yet! How far back can she bill for?

Each insurance has it own timely file limit.   

for instance...United HealthCare has a 90 day time file.

Medicare you can bill from Oct '08 to current and get paid on.

The easiest way is to call the insurance companies and ask them what their timely file limit is and go from there.   You may be able to appeal a few but, it will be tough.

varies by carrier, and contract(par v/s non par)

Also before any of that, there are legalities that have to be worked out such as the exact purchase of the practice.. sometimes receivables are NOT included in the sale or takeover of a practice.

i was under the assumption she was meaning the one that took over hasn't billed since she did in september....that she wasn't talking about billing what the PREVIOUS provider had done.
