Certified Billing Coding Specialist (CBCS) The CBCS exam focuses heavily on ICD-10-CM diagnosis coding accuracy, CPT procedure code selection, and HCPCS modifiers? plus the nuances of medical necessity documentation. You’ll need precision with bundling rules, unbundling penalties, and how payer-specific edits affect claim adjudication. Real-world scenarios require distinguishing between legitimate upcoding versus appropriate code selection.
