About this exam

The Certified Coding Specialist (CCS) is an AHIMA credential for individuals skilled in classifying medical data from medical records. CCS holders demonstrate tested skills in data quality and accuracy as well as mastery of coding proficiency, and the coded data they produce is used by hospitals and providers to obtain reimbursement from insurers and government programs such as Medicare and Medicaid; researchers and public health officials also use it to monitor patterns and explore new interventions. The credential is a natural progression for professionals experienced in coding inpatient and outpatient records, or for those who already hold the CCA. The exam spans five domains: Coding Knowledge and Skills, Coding Documentation, Provider Queries, Regulatory Compliance, and Information Technologies. It is a computer-based test of 107 questions - 97 scored and 10 pretest - delivered at Pearson VUE testing centers over four hours, with a passing score of 300. Preparation is flexible: AHIMA recommends but does not require coursework in anatomy and physiology, pathophysiology, pharmacology, medical terminology, reimbursement methodology, ICD diagnostic coding and CPT/HCPCS procedural coding plus one year of hands-on coding experience, or an equivalent mix of experience and credentials. AHIMA's prep books and online courses are optional. This page is an independent study resource and is not affiliated with AHIMA.

What you'll study

Common questions

About CCS preparation

How long is the CCS exam and how many questions does it contain?

There are 107 questions in total: 97 scored items and 10 pretest items, randomly distributed throughout the exam. You get four hours, testing on computer at a Pearson VUE center. Once you have selected an answer you can move back and forth between items and flag questions to review before submitting, as time allows.

What score do I need to pass?

The passing score for the CCS is 300. Only the 97 scored items count toward your result - the 10 pretest items are included for data collection and do not count toward a candidate's score. That means a few unfamiliar or oddly worded questions on test day are normal and should not rattle you.

If I fail, how soon can I retest and what does it cost?

You must submit a new application with the relevant exam fee and wait at least 30 days before your application is approved. Transcripts already on file do not need resubmitting. You cannot schedule until a new authorization to test letter is issued, and AHIMA will not waive retest periods. Retake fees match the exam price: $299 member, $399 nonmember.

What does the exam cost, and what happens if I reschedule or cancel?

The CCS costs $299 for AHIMA members and $399 for nonmembers. You can cancel or reschedule up to 15 days before your test date at no charge; between 14 days and 24 hours prior, Pearson VUE charges $30. No rescheduling inside 24 hours. Refund requests carry a $75 processing fee and must be filed at least 14 business days before your test date or eligibility end date.

Do I need coding experience or coursework to sit for the exam?

It is recommended, not required, to have one of: coursework in anatomy and physiology, pathophysiology, pharmacology, medical terminology, reimbursement methodology, intermediate/advanced ICD diagnostic coding, and CPT/HCPCS procedural coding plus one year applying codes; two years of related coding experience; a CCA plus one year; another organization's coding credential plus one year; or a CCS-P, RHIT, or RHIA.

Which code books must I bring on test day?

Exams delivered on or after May 1, 2026 require the 2026 code books from AHIMA's 2026 required code book list. Every candidate must bring the correct code books to the test center - anyone without them is not allowed to test and forfeits their exam fees. Verify the list well before your appointment date.

In what order should I study the five domains?

No sequence is mandated. A sensible plan is diagnostic and procedural coding plus documentation first, since they anchor query practice, then provider queries, regulatory compliance, and information technologies. AHIMA prep products organize practice questions by competency and by task within each domain, so a pretest can show which task areas need the most review. Finish with full-length practice exams and medical scenarios.

What trips candidates up most often on this exam?

The exam is applied rather than recall-based: inpatient and outpatient medical scenarios ask you to read documentation and assign codes under a four-hour clock. Candidates who only memorize code lists tend to lose time and accuracy, and flagging too many items for later review can leave nothing in reserve. Practice timed scenarios, not just isolated questions.

How far ahead should I book my appointment?

After your application is approved, schedule with Pearson VUE within 120 days of eligibility. Booking early protects your preparation timeline and keeps you inside the free cancellation window, which closes 15 days before the test date. Arrive on time - candidates 30 or more minutes late are not allowed to test and forfeit their fees.

How long does the CCS stay valid, and how do I keep it?

The credential runs on a two-year certification period. To maintain it you must complete all recertification requirements during that cycle, which include submitting the required amount of continuing education units (CEUs) and paying the recertification fee. AHIMA's Recertification Hub lists CEU opportunities and walks through the process.
