CPC cheatsheet

CPC high-yield coding-concept drill

The rule

Index, then Tabular. Code only what the record supports at the stated specificity. This drill never uses AMA-licensed procedure codes.

Next step

If laterality, episode, or the procedure itself is missing, query. Do not guess the side or complete a cancelled service.

Never miss

  • Never code from the Alphabetic Index alone.
  • Excludes1 is mutually exclusive. Excludes2 allows both when documented.
  • Outpatient uncertain diagnoses are not coded as confirmed.
  • CMS office E/M is medical decision making or time, not history-and-exam bullets.
  • A modifier that means distinct service needs a documented distinct service.
  • HCPCS Level II is the CMS public set for supplies, drugs, and DME concepts.

Traps

  • Coding a cancelled procedure as completed.
  • Picking the side that groups better.
  • Reporting family history as the active disease.
  • Bypassing every NCCI edit with the same modifier.

Shortcuts

  • Highest documented character, then stop.
  • Integral signs sit inside the confirmed diagnosis.
  • Queries are non-leading.

Terms

  • Tabular List. The verification step after the Alphabetic Index.
  • Excludes1. The two conditions should not be coded together.
  • Excludes2. Both conditions may be coded when both are documented.
  • Combination code. One code that captures a stated causal pair.
  • MUE. Medically unlikely edit. Units that exceed what CMS considers likely for one date.
  • MDM. Medical decision making. One of two ways to level office E/M under current CMS policy.

Memory hooks

  • INDEX-THEN-TABULAR. Find it, then verify it The official ICD-10-CM motion.
  • -ectomy / -ostomy / -itis / -scopy. Removal / opening / inflammation / looking High-yield suffixes.
