ICD-10-CA: Precision Coding
Move beyond basic code-searching to master the nuances of Canadian diagnostic classification, sequencing, and data integrity standards.
Like Duolingo, but for ICD-10-CA: Precision Coding. Tomo turns the whole topic into a game you play five minutes a day, until it actually sticks.
24 levels across 3 sections, about 48 minutes end to end, roughly 10 days at five minutes a day. It moves through The Logic of Sequencing, Navigating Complex Classifications, and Standards and Data Integrity. It assumes you already know the basics.

Key ideas in ICD-10-CA: Precision Coding
- The Main Problem is determined after study rather than at admission
- Resource intensity determines the Main Problem among competing conditions
- The reason for admission is the symptom that brought the patient to the ER
- The Main Problem is the underlying condition found to be responsible for the stay
- In day surgery, the Main Problem is the condition that scheduled the intervention
- Inpatient stays prioritize the condition treated, but day surgery focuses on the intent
- Differentiating reason for admission from the resource-heavy Main Problem
- Applying Main Problem logic to day surgery versus inpatient stays
- If no diagnosis is found, code the presenting symptom or abnormal finding.
- Coding 'suspected' conditions as confirmed is generally avoided in the Main Problem field.
- Handling cases where no definitive diagnosis is reached
- Secondary codes must meet significance criteria
- Main Problem determined after study
- Exclude conditions that don't alter clinical path
- Sequencing prioritizes resource-intensive interventions
- Resource intensity determines Main Problem
You've tried the other tabs
Thirty open tabs. Four facts you actually kept.
You watched. You nodded. By Sunday it was gone.
One answer, then back to scrolling.
Eight weeks. You meant to finish. You didn't.
Tomo gives ICD-10-CA: Precision Coding the Duolingo treatment: levels, streaks, and quick quizzes that test what you just learned. That game loop is what the tabs above never had, so it's the one you actually finish.
Here's what playing it feels like
A real question from this course. Take your best guess.
Why shouldn't we always use the diagnosis documented at the moment of admission as the Main Problem?
