Can physicians or practitioners who are suppliers of Durable Medical Equipment Prosthetics Orthotics and Supplies (DMEPOS), Independent Diagnostic Testing Facilities (IDTFs), clinical laboratories, etc., opt out of Medicare for only these services?

No. If a physician or practitioner chooses to opt out of Medicare, it means that he or she opts out for all covered items and services he or she furnishes. Physicians and practitioners cannot have private contracts that apply to some covered services they furnish but not to others. In addition, because suppliers of DMEPOS, independent diagnostic testing facilities, clinical laboratories, etc., cannot opt out, the physician or practitioner owner of such suppliers cannot opt out as such a supplier
