I am doing some work for a group of perinatologists. Is it ok to bill for critical care services which take place immediately following labor and delivery? I've heard from some that this is included in the global fee for the L&D, and I've heard from others that it can be billed separately. Does anyone do billing and coding for perinatologist? How do you handle these cases where your doc is spending lots of observation time post L&D with acutely hypertensive moms for example?
