Why this test matters
Medical coders typically don't need elite WPM — 40–60 WPM is the working norm. What they need is sustained accuracy on alphanumeric strings: ICD-10 codes like `S52.501A` or CPT codes like `99213-25` have no semantic cushion, so a single transposed character means a denied claim and hours of rework. Most certifying bodies (AAPC, AHIMA) don't formally test typing speed, but coding employers screen for 40–50 WPM at 97%+ accuracy. The 3-minute test below uses prose vocabulary, not coding strings — but treat it as your daily accuracy check. If your accuracy drops below 96% on this test, your coding accuracy is at risk too. Most experienced coders maintain 98%+ on prose tests, which translates to near-zero coding errors over an 8-hour shift.
