A description drifts into the center of a 3D field while four candidate ICD-10-CM codes orbit around it. Pick the right one before the timer runs out. The distractors are the codes that actually get miscoded in production — wrong laterality, wrong encounter character, wrong specificity — so a fast guess is usually the wrong guess.
Every code that appears here has a full reference page on this site — descriptions, inclusion terms, Excludes1/Excludes2 notes, and crosswalks. Look one up →
Study aid only — not coding, billing, legal, or medical advice. Verify every code against the current official code set and your payer’s policy before billing.
Scores are submitted by players and shown as entered. Play a round to add yours.
Give it a heart so other coders can find it, and send it to someone on your team who needs the practice.
