Medical coding and billing are two essential, yet distinct processes in the healthcare revenue cycle. Both work together to ensure that healthcare providers get paid for services rendered—but their functions are different.

Support audits and reporting requirements
Workflow:

Responsibilities:
-
Prepare and submit claims to insurance companies

-
Generate patient bills for remaining balances
Workflow:
