Free Coding Guidelines drillHow to study it
- Read the guidelines at the front of each CPT section and of the ICD-10-CM book; tab them for the exam.
- Make a one-page modifier chart in your own words and test yourself until you can name each one.
- Learn the outpatient rule for "probable" and "rule out": code the symptom, not the uncertain diagnosis.
- Take the coding guidelines drill more than once; these rules also decide the coding questions.
