I am billing Medicare for Doctor of Osteopathy (DO) using 2 codes: E/M code99213 with modifier 25 and code 98926 - osteopathic manipulation. For many years we got payment for both codes. Suddenly, week ago I got payment only for code 98926 and zero for code 99213 wich was bundled with code 98926. What happened? And what can I do?
Thanks.
Thanks.
