Cheat Sheet
- ICD-10-CM vs. CPT Code Structure -
ICD-10-CM codes classify diagnoses with a three-to-seven character alphanumeric format, while CPT codes use five numeric digits for procedures. For example, E11.9 designates Type 2 diabetes mellitus without complications and 99213 indicates an established patient office visit. Mnemonic trick: "ICD-TEN has letters, CPT is all digits!"
- Accurate Documentation & Compliance -
Strong documentation under HIPAA and CMS guidelines is critical to demonstrate medical necessity and avoid denials on a medical billing and coding practice test. Always cross-reference physician notes with ICD-10-CM and CPT code definitions to ensure specificity. AU of thumb: "If it's not in the chart, it didn't happen."
- Modifiers and Bundling Rules -
Mastering NCCI edits and modifier usage - like appending -25 for a significant, separately identifiable E/M service - helps you tackle complex scenarios on a billing and coding practice exam. Remember that unbundling bundled services is prohibited and can trigger audits. Think "Modifier makes it matter!" to recall the extra element.
- Claim Forms & Electronic Submission -
Know the CMS-1500 and UB-04 forms inside out and practice completing them accurately for a medical billing coding test. Electronic claims use ANSI X12 837 format, reducing errors and speeding reimbursement. Pro tip: validate field entries with free CMS companion guides before submission.
- Reimbursement Methodologies -
Familiarize yourself with RVUs, the Medicare Physician Fee Schedule, and DRG assignments to predict payment outcomes on a medical billing practice exam. RVU = Work RVU + Practice Expense RVU + Malpractice RVU, then multiplied by the conversion factor. Use the formula "Total RVU × CF = Medicare payment" as a quick reference.
