What "CASCC Requirements" Actually Covers
When people search for CASCC requirements, they're usually asking three different questions at once: Am I eligible to take the exam? What do I need to bring or set up on test day? And what do I need to do afterward to keep the credential active? The Certified Ambulatory Surgery Center Coder (CASCC) credential, administered by AAPC, bundles all three into a fairly specific set of rules - membership status, exam logistics, reference materials, and continuing education. This guide walks through each requirement in order, so you know exactly what's expected before you register.
If you haven't already reviewed the exam's content structure, it's worth pairing this page with the CASCC Exam Domains 2026 guide, since several eligibility and preparation decisions depend on which domains carry the most weight for your background.
Who Is Eligible to Sit for the Exam
CASCC is built for coders who already have hands-on exposure to ambulatory surgery center coding - not as an entry-level starting point. The exam assumes advanced familiarity with medical terminology, anatomy, pathophysiology, and CPT, ICD-10-CM, and HCPCS Level II coding as applied specifically to ASC operative notes. There is no separate prior-credential gate published for CASCC beyond holding active AAPC membership, but the content and pacing are designed around experienced coders, not newcomers.
In practice, that means candidates typically come in with:
- Working experience coding ASC operative reports, not just inpatient or physician-office charts
- Comfort translating dictated surgical language into correct code sets under time pressure
- Some exposure to ASC-specific payment rules, since a full domain is devoted to reimbursement logic
If you're still deciding whether your background is strong enough to attempt CASCC now or later, the difficulty breakdown in How Hard Is the CASCC Exam? Complete Difficulty Guide 2026 is a useful sanity check before you commit to a registration fee.
The AAPC Membership Requirement
Current AAPC membership is a hard requirement to sit for the CASCC exam, and it doesn't stop there - you must maintain membership to keep the credential active after you pass. This is one of the most overlooked "requirements" because candidates often budget for the exam fee and forget membership is a recurring, separate cost tied to holding the letters CASCC after your name.
Before you register, confirm your membership status is current in your AAPC account. A lapsed membership at the time of registration or exam scheduling can delay your ability to sit for the test, so this is worth checking weeks in advance rather than the night before you book a slot.
Registration and Fee Mechanics
The CASCC specialty exam is priced at $325 for a single attempt or $399 if you want a two-attempt package. The two-attempt option is worth considering if you're not fully confident after your first study pass, since it locks in a retake at a lower combined cost than paying full price twice.
- Delivery is through Meazure Learning, with ProctorU used for live remote proctored sessions
- A traditional computer-based testing center option is also available if you prefer not to test from home
- Current AAPC membership must be active at the time of registration

Key Takeaway
Decide between the one-attempt and two-attempt registration option based on how confident you are in your ASC-specific operative note coding speed - not just your general CPT/ICD-10-CM knowledge.
Exam Format Requirements
The CASCC exam consists of 100 proctored multiple-choice questions, and you're given four hours to complete it. It is an open code book exam, meaning you're allowed to reference your approved manuals during the test - but that's not the same as an easy exam. With 100 questions in four hours, you have roughly two and a half minutes per question on average, and many questions require you to first work through an operative note before you can even look anything up.
To pass, you need a score of 70%, which works out to 70 correct answers out of the 100 questions. There's no partial-credit ambiguity here - it's a straightforward raw score threshold. For a deeper look at how that scoring threshold is calculated and what it means in practice, see CASCC Passing Score 2026: Exactly What You Need to Pass.
| Requirement | Detail |
|---|---|
| Question count | 100 multiple-choice questions |
| Time allowed | 4 hours |
| Passing score | 70% (70 correct answers) |
| Reference policy | Open code book |
| Registration fee | $325 (one attempt) or $399 (two attempts) |
| Membership status | Current AAPC membership required |
Approved Code Book and Reference Rules
Because CASCC is an open-book exam, what you're allowed to bring matters just as much as what you know. The approved references are strictly limited to three manuals:
- AMA CPT Professional Edition
- ICD-10-CM
- HCPCS Level II
You're permitted one copy of each. Current-year editions are recommended, and the current or immediately preceding year's edition is permitted if that's what you have on hand. If you're testing remotely, you must select either a print format or a platform-eBook format at least 48 hours before your exam - and you cannot mix formats, meaning you can't bring a print CPT book alongside an eBook ICD-10-CM manual. Decide on your format early and stick with it across all three references.
Remote Testing Technical Requirements
If you take the live remote proctored version through ProctorU rather than testing at a physical center, you need to meet specific technical conditions:
- A private room where you won't be interrupted during the exam window
- Reliable internet connection strong enough to sustain a live video proctoring session
- A computer that meets the platform's testing requirements
- An external webcam positioned to give the proctor a clear view of you and your workspace
- A government-issued photo ID that matches the name on your AAPC registration
Test these requirements - especially your webcam angle and internet stability - the day before your exam, not the morning of. A failed connectivity check can cost you valuable minutes of your four-hour window or force a reschedule.
The Seven Domains You Must Be Ready For
CASCC eligibility isn't just about paperwork and fees - it's ultimately about whether you can demonstrate competency across seven tested domains. Understanding what each domain actually demands is part of qualifying in a practical sense, even if it's not a formal checkbox on a registration form.
Domain 1: Operative Note Dissection and Code Assignment
Reading full operative notes and correctly applying ICD-10-CM, CPT, HCPCS Level II, and modifier codes based on what was actually documented.
- Distinguishing primary procedures from incidental findings within a note
Domain 2: Types of Surgery Performed in the ASC Setting
Familiarity with the range of procedures commonly performed outside inpatient hospitals, across specialties.
- Recognizing which procedure types are ASC-appropriate versus hospital-only
Domain 3: Ancillary Procedures, Drugs, and Biologicals
Coding supporting services and supply items that accompany the primary surgical procedure.
- Correctly capturing drugs and biologicals administered during the encounter
Domain 4: ASC Reimbursement Rules
Understanding multiple procedure discounting, device-intensive procedure payment logic, and discontinued procedure billing.
- Applying the correct modifier and payment logic for terminated procedures
Domain 5: Regulatory Standards
Awareness of federal and state regulatory frameworks that govern ASC billing and documentation practices.
Domain 6 & 7: Medical Terminology and Anatomy/Physiology
Foundational knowledge that underpins accurate interpretation of every operative note you'll encounter on the exam.

Requirements to Maintain the Credential
Passing the exam only satisfies the first half of the requirement structure. To keep CASCC active, you must:
- Maintain annual AAPC membership continuously
- Complete 36 CEUs every two years specific to this credential
- Ensure at least 8 of those CEUs are ASC-specific content
This maintenance requirement is a meaningful long-term cost and time commitment, and it's worth factoring into your decision about whether the credential fits your career plans.

A Realistic Path to Meeting the Requirements
Meeting CASCC's requirements is as much about preparation sequencing as it is about paperwork. Rather than a generic study calendar, sequence your prep around the domains that carry the heaviest exam-day weight and the reference rules you'll actually use.
Domains 1, 6, 7 - Terminology, Anatomy, Note Dissection
- Practice reading full ASC operative notes and identifying key procedure language before touching a code book
Domains 2 and 3 - Surgery Types and Ancillary Coding
- Build familiarity with drugs, biologicals, and ancillary codes that pair with common ASC procedures
Domains 4 and 5 - Reimbursement and Regulatory Rules
- Drill multiple, device-intensive, and discontinued procedure billing scenarios repeatedly, since these trip up even experienced coders
Full-Length Practice Under Timed Conditions
- Simulate the four-hour, 100-question format using only your approved CPT, ICD-10-CM, and HCPCS Level II references

Frequently Asked Questions
There is no separate prior-credential requirement published for CASCC beyond active AAPC membership. However, the exam content assumes experienced-level knowledge of ASC coding, so most successful candidates already have hands-on ASC coding background.
Membership must be maintained annually to keep the credential active. Combined with the 36 CEUs required every two years (including 8 ASC-specific CEUs), membership is an ongoing requirement, not a one-time gate.
Yes. In addition to live remote proctored testing through ProctorU, computer-based testing at a physical testing center is also offered as a delivery option.
Only the AMA CPT Professional Edition, ICD-10-CM, and HCPCS Level II - one copy of each. Current-year editions are recommended, and the current or immediately preceding year is permitted.
One attempt costs $325, while a two-attempt package costs $399. If you have any doubt about passing on your first try, the two-attempt option provides a built-in retake at a lower combined cost than paying twice.
