Final answer:
The claim that physicians use CMS-1450 is false; physicians use the CMS-1500 form for Medicare claims, while the CMS-1450, or UB-04, is used by institutional providers like hospitals.
Step-by-step explanation:
The statement that 'The paper claim used by physician is the CMS-1450' is false. Physicians and other noninstitutional providers typically use the CMS-1500 form to submit Medicare claims. The CMS-1450, also known as the UB-04, is generally used by institutional providers such as hospitals and nursing facilities for billing medical and mental health services and supplies. It is important for billing and coding professionals to use the correct form to ensure proper claim processing and reimbursement.
