Certified Professional Coder-Payer (CPC-PÂ®) More private and public payers (health plans) are recognizing the value of employing certified coders to process and analyze medical claims for payment. The CPC-PÂ® credential meets the growing demand for certified coders in a payer environment.

These qualifications are offered by OCR on behalf of the Department for Transport and cover a range of areas related to the business of road haulage or passenger transport management.xample: If you hold (from the previous CPC) Units 1 and 3, but not Unit 4, then you will need to take Units R1 and R2 to gain the new 2012 CPC in Road Haulage. This is because the previous units and the new units are too different to allow them to be used together to form a full CPC.
