The CRC Exam Content Outline, Domain by Domain (2026 Guide)
Share
I've been coding risk adjustment for long enough that I can spot a chart that's going to lose a Hierarchical Condition Category before I finish the first progress note. When I sat the CRC, the thing that surprised me wasn't the coding — it was how much of the exam lives outside the code book: audit logic, documentation gaps, model mechanics, quality programs. The content outline tells you that in advance, if you read it properly.
So let's read it properly. Here's what the seven CRC domains cover, where the published weights get confusing, and how to turn the blueprint into a study order that actually matches how the exam feels.
The seven content domains, and what AAPC actually publishes
AAPC's CRC exam description lists seven content domains:
- Compliance
- Diagnosis Coding
- Documentation Improvement
- Pathophysiology / Medical Terminology / Anatomy
- Purpose and Use of Risk Adjustment Models
- Quality Care
- Risk Adjustment Models
Those names are official. Diagnosis Coding is the largest section, followed by Risk Adjustment Models and then Compliance. That ordering is the single most useful thing on the outline, because it tells you where to put your hours without needing an exact count per topic.
The exam itself is 100 multiple-choice questions answered in 4 hours, in one sitting. If you've been reading older prep material that describes a 150-question paper, that's the retired format — AAPC standardized to the 100-question, 4-hour structure. We break the current structure down further in our overview of the CRC exam and its format.
Why the published per-domain numbers don't add up
This trips up almost everyone who prints the outline and starts building a spreadsheet. AAPC's published per-domain CRC question counts (Compliance 23, Diagnosis Coding 60, Documentation Improvement 18, Pathophysiology/Medical Terminology/Anatomy 8, Purpose and Use of Risk Adjustment Models 15, Quality Care 5, Risk Adjustment Models 21) sum to 150 and reflect the retired 150-question format — they are inconsistent with the current 100-question exam. Use AAPC's current CRC content outline for the up-to-date counts.
What that means in practice: treat those figures as a proportional hint, not a target. The relative shape is still informative — diagnosis coding dominates, risk adjustment models and compliance are heavy, pathophysiology and quality care are thin. But do not plan a question-by-question budget off numbers built for an exam that no longer exists.
The retired 150-question weight table (for context only)
| Domain | Retired-format count |
|---|---|
| Diagnosis Coding | 60 |
| Compliance | 23 |
| Risk Adjustment Models | 21 |
| Documentation Improvement | 18 |
| Purpose and Use of Risk Adjustment Models | 15 |
| Pathophysiology / Medical Terminology / Anatomy | 8 |
| Quality Care | 5 |
These sum to 150 and belong to the retired format. Confirm current counts on AAPC's live CRC content outline.
Domain by domain: what the questions feel like
Diagnosis Coding
This is the anchor. Expect ICD-10-CM guideline application under time pressure: laterality, combination codes, "with" conventions, excludes notes, sequencing, manifestation coding, and the endless diabetes and CKD permutations. Half my working day is deciding whether documentation supports a specific code or only an unspecified one, and the exam asks that same question over and over in miniature.
Risk Adjustment Models
Model mechanics: how conditions map to categories, how hierarchies suppress lower-severity siblings, how demographics and interactions factor in, and what resets year to year. You need to be comfortable reasoning about which of two documented conditions actually carries the weight.
Compliance
Audit exposure, RADV concepts, chart review rules, the difference between supported and unsupported diagnoses, and what "cloned" or unsigned documentation does to a submission. Compliance questions often look like coding questions until you notice the trap is provenance, not the code itself.
Documentation Improvement
Query practice, compliant versus leading queries, identifying gaps that block a specific code, and knowing what a provider must state for a condition to count as monitored, evaluated, assessed, or treated.
Purpose and Use of Risk Adjustment Models
The "why" layer: payment methodology, plan and program context, budget-neutrality style concepts, and how risk scores feed reimbursement. Lighter than the coding domains, but pure recall — cheap points if you read the material once.
Pathophysiology / Medical Terminology / Anatomy
Small but real. Disease processes behind the high-value chronic conditions, terminology roots, and enough anatomy to tell whether a documented finding is plausible for the code selected.
Quality Care
The thinnest slice. Quality measures, care-gap closure, and how quality programs intersect with risk adjustment documentation. Don't over-invest here.
How the format constrains your blueprint prep
Every one of those domains has to be handled inside 4 hours, with 100 questions in front of you. That's the whole time budget — a single sitting, no split parts. The exam is open-book with approved code manual(s), primarily ICD-10-CM, since the CRC centers on diagnosis coding and risk adjustment. Officially published errata sheets are permitted and no other references are allowed. One caveat worth acting on: the exact approved-manual list specific to the CRC wasn't confirmable from a fetchable official source, so confirm the current CRC-specific manual allowances on AAPC's exam page before you pack your bag.
Open-book cuts both ways. The coding domains reward a heavily tabbed, familiar manual. The compliance, model, and quality domains largely don't — you either know the concept or you burn minutes flipping for something that isn't in there. That asymmetry should drive your prep: book skills for Diagnosis Coding, memory and reasoning for everything else. If you're mapping out weeks, our study-timeline breakdown pairs well with this blueprint.
Scoring: one flat standard across all seven domains
AAPC requires an overall score of 70% or higher to pass — at least 70 of 100 questions correct. Each question is weighted equally at one point, and the 70% standard is overall, not per-section. There's no scaled-score conversion published for the CRC, and no minimum you have to clear inside any individual domain.
Two related points people ask about. AAPC does not publish a scored-vs-pretest split for the CRC exam; the 70% pass standard (70 of 100 correct) implies all 100 are scored. And AAPC does not publish a pretest/unscored (pilot) question count for the CRC exam. Separately, AAPC does not publish an official CRC pass-rate percentage, so treat any figure you see quoted in a forum as folklore. More on the threshold in our CRC passing score guide.
The practical read: because scoring is flat, a weak domain can be absorbed by strength elsewhere. Missing most of Quality Care won't sink you. Missing a chunk of Diagnosis Coding will.
Logistics that affect when you can test the blueprint
| Item | Detail |
|---|---|
| Questions / time | 100 multiple-choice, 4 hours, single sitting |
| Pass standard | 70% or higher (at least 70 of 100 correct) |
| Fee | $425 (1 attempt) or $499 (2 attempts); student pricing $400 (1) / $475 (2) |
| Membership | Active AAPC membership required (dues separate) |
| Delivery | Online Live Remote Proctored via external webcam, proctored by Examity, or in person at an approved exam site |
| Scheduling | By appointment after purchasing a voucher; must be taken within one year of purchase |
| Retake | Second attempt included with the 2-attempt purchase; free retake must be used within one year of the original exam date |
On fees, one flag: older AAPC and forum content cites lower dollar figures that appear to predate the current schedule, so verify the price on AAPC's exam-cost page before you buy. And note the single-attempt purchase does not include a free retake; all exam fees are non-refundable and non-transferable.
Eligibility is light. There's no mandatory education or experience prerequisite to sit, though AAPC recommends relevant experience — commonly two years of coding or risk-adjustment work — and an associate's degree. Active AAPC membership is required at the time of exam application and/or when results are released. The full walkthrough lives in our question count and registration guide.
Turning the blueprint into a study order
Here's the sequence I'd use if I were starting over, built on domain size rather than invented percentages:
- Diagnosis Coding first, and keep coming back to it. It's the largest domain and the one where speed compounds. Drill guideline conventions in the manual until lookups are reflexive.
- Risk Adjustment Models second. Hierarchies and category logic take repetition to stick. Work them as puzzles, not flashcards.
- Compliance third. Audit and chart-review rules are memorizable and consistently tested.
- Documentation Improvement fourth. Query rules overlap heavily with compliance, so studying them back to back saves time.
- Purpose and Use of Risk Adjustment Models, then Pathophysiology and Quality Care. Lighter reading. Schedule them for tired evenings.
Then do timed sets. Not because you'll run out of clock — 4 hours is workable — but because open-book habits only form under pressure. If you're still deciding whether the credential fits your path, our comparisons of CPC, CRC, CCA and other tracks are worth a read before you spend the voucher.
The takeaway
The CRC blueprint is seven domains, tested across 100 questions in 4 hours, scored flat at 70% or higher with every question worth one point. The per-domain counts you'll find floating around belong to the retired 150-question exam, so pull the current outline from AAPC rather than trusting a screenshot. Study in proportion to what AAPC still confirms — Diagnosis Coding largest, then Risk Adjustment Models, then Compliance — and verify fees, manual allowances, and scheduling windows on AAPC's own pages before you commit.
