ACP helps Medicare patients decide the plan of care that they would like to get when they are unable to take such decisions themselves.
Voluntary ACP is a face-to-face service between a physician (or other qualified health care professional) and a patient discussing advance directives with or without completing relevant legal forms. An advance directive is a document in which a patient appoints an agent and/or records the wishes of a patient pertaining to their medical treatment at a future time if they cannot decide for themselves at that time.
There are no limits on the number of times you can report ACP for a given patient in a given time period. When billing the service multiple times for a given patient, document the change in the patient's health status and/or wishes regarding their end-of-life care.
There are no place-of-service limitations on ACP services. You can appropriately furnish ACP services in facility and non-facility settings. ACP services are not limited to a
particular physician specialty.
CMS requires no specific diagnosis to bill the ACP codes.
