Study Materials
Master every topic of the exam, in plain language.
Medical Coding: ICD-10-CM, CPT, and HCPCS
Coding translates documented diagnoses and services into standardized codes. The CBCS exam is closed-book, so you must know the code-set conventions, structure, modifiers, and sequencing rules from memory rather than looking them up.
Billing and Claims Processing
Billing converts coded encounters into claims, submits them to the correct payer, and resolves the payer response. Success depends on clean claims, correct forms, knowledge of payer types, and disciplined denial follow-up.
Compliance and Regulatory Standards
Billing specialists operate under federal privacy, security, and fraud-and-abuse laws. Understanding HIPAA, the False Claims Act, the Anti-Kickback Statute, and documentation rules protects patients and shields the practice from penalties.
Reimbursement Methodologies and Patient Financials
Reimbursement is how providers get paid and how patient responsibility is calculated. Expect math: coinsurance and deductibles are figured from the allowed amount, not the billed charge.
