For discussion: To what extent do you think billing and especially reimbursement guidelines effect what procedures and tests are offered or withheld from patients? How granular (or invasive) do you think those guidelines can realistically be without impacting patient care? How effective do you think the CMS (aka Medicare) guidelines are at curtailing illicit or "ethically gray" practices? Apply this to private insurance. Who do you think provides more stringent reimbursement guidance: private insurance or government provided Medicare/Medicaid? Why do you think that way? How might that affect compensation and hospital insurance provider preference
