Everyone should read the same short foundation first. After that, jump to your own work. The whole foundation takes about twenty minutes, and it is what makes every other guide make sense.

Read these first, whoever you are

These four explain how coding turns into income, and they underlie everything else on the site.

  1. Why Coding Matters, the direct link between your notes and your paycheck.
  2. How You Get Paid, wRVUs, the conversion factor, and the fee schedule, in plain language.
  3. Medical Decision Making Decoded, the engine that sets the level of most visits.
  4. Choosing Your Level, worked examples and the mistakes auditors look for.

If you do primary care or internal medicine

  1. The 25 Codes That Pay Primary Care
  2. G2211, the add-on most eligible clinicians are not using.
  3. Medicare Annual Wellness Visits and AWV plus a same-day problem.
  4. Counseling Services, the work you are giving away.

If you are in a surgical specialty

  1. Surgical Coding Overview, the global package and its exceptions. Read this one first.
  2. Modifier 25 and the modifier family (24, 25, 57, 58, 78, 79).
  3. Then your specialty: orthopaedics, fracture care, or sports medicine procedures.

If you work in the hospital or emergency department

  1. Hospitalist Coding, after the 2023 observation merger.
  2. Emergency Medicine Coding, levels and critical care.
  3. Billing by Time and Prolonged Services.

If you are a nurse practitioner or physician assistant

  1. Advanced Practice Providers, the 85% rule and what it means for you.
  2. Incident-To Billing, the rules and the risks.
  3. Then the foundation above, which applies to your coding exactly as it does to a physician's.

If you lead a group or want to improve a whole practice

  1. Undercoding, where the money usually leaks.
  2. Building a Coding Culture, how to bring this to colleagues without becoming the compliance police.
  3. Building Your Personal Coding Dashboard and the wRVU Tracker tool.

When you want a quick desk reference, grab the one-page cheat sheet, browse the documentation templates, or keep the glossary open in a tab.
