Previously if a patient was admitted for an observation status which turned into an admit status, an office would bill the admit charge as it was the highest level. However, there are some changes with Medicare and the guidelines of observation and 2 midnight stays? Can someone tell me what has changed with Medicare and how the claim should be billed. The office is getting rejects from Medicare for the admit charges. With these changes, does it only apply to Medicare or other carriers? I appreciate any responses!
