How do we bill out a myocardial perfusion scan that is performed over a two-day period? Does it get billed out on the date it is started or on the day it is finished?
There is no definitive answer to that (unless a particular payer has established a policy concerning date of service). It could be either date, but you should be consistent in what you do. Make it a part of your policies and procedures and bill the same way each time.
If you bill for the radiopharmaceutical itself (HCPCS code), then that must be billed on the date it is given.
