Jill Tucker, RN says:

“ ‘Ask your doctor’. But your doctor receives much greater compensation from Medicare and Medicaid to perform tests or procedures than to sit and discuss preventative care or long-term planning. A new bill would level that paying field and provide greater reimbursement to doctors engaging in “cognitive services”—professional thought, judgement and opinions on topics such as end-of-life scenarios and DNR requests. For many patients, talk can be a very valuable treatment.”
