Sample CCS Practice Questions

Try these sample questions to review concepts for the CCS exam. Each question includes a detailed explanation. Start the interactive quiz above for the full 493+ question experience with AI tutoring.

1An inpatient is admitted solely for treatment of anemia due to documented active primary lung cancer. Which diagnosis is sequenced first?
A.D63.0, anemia in neoplastic disease
B.C34.90, active primary lung malignancy
C.D64.9, anemia unspecified
D.Z85.118, history of lung malignancy
Explanation: FY 2026 ICD-10-CM guideline I.C.2.c.1 sequences the active malignancy first when admission is solely for anemia associated with that malignancy, followed by D63.0. The cancer site is documented as current, not history.
2A patient has type 2 diabetes with documented diabetic nephropathy, but no chronic kidney disease diagnosis or stage. Which code is supported?
A.E11.9 and N18.9
B.E11.21 only
C.E11.22 only
D.E11.9 only
Explanation: E11.21 captures type 2 diabetes with diabetic nephropathy. Do not add N18.9 or E11.22 without documented CKD. A nephropathy diagnosis alone does not establish an additional CKD stage.
3In ICD-10-CM, what does the seventh character "A" indicate in injury codes?
A.Subsequent encounter
B.Sequela
C.Initial encounter
D.Not applicable
Explanation: In ICD-10-CM injury codes (categories S00-T88), the seventh character "A" indicates an initial encounter. This is used when the patient is receiving active treatment for the condition. "D" indicates a subsequent encounter, and "S" indicates a sequela (late effect).
4A patient is admitted with pneumonia due to MRSA (methicillin-resistant Staphylococcus aureus). The correct ICD-10-CM coding includes:
A.J15.212 only
B.J18.9, B95.62
C.J15.212, Z16.24
D.J15.212, B95.62
Explanation: J15.212 is pneumonia due to MRSA and already identifies the organism. B95.62 is not added solely to repeat MRSA in a combination code. Additional MRSA carrier or resistance codes require their own documented indications.
5According to ICD-10-CM guidelines, when should a code from category Z38 (Liveborn infants according to place of birth and type of delivery) be assigned?
A.Only for the newborn's birth record
B.For all encounters during the first year of life
C.For any encounter involving a newborn
D.Only when the birth was by cesarean section
Explanation: Per ICD-10-CM Official Guidelines Section I.C.16.a.1, a code from category Z38 should be assigned only once, to the newborn at the time of birth. If the newborn is transferred to another institution, the Z38 code should not be repeated at the receiving facility.
6A patient undergoes a laparoscopic cholecystectomy. What is the correct ICD-10-PCS root operation for this procedure?
A.Resection
B.Excision
C.Removal
D.Destruction
Explanation: A cholecystectomy (removal of the gallbladder) is coded with the root operation "Resection" in ICD-10-PCS. Resection is defined as cutting out or off, without replacement, all of a body part. The complete code would be 0FT44ZZ (Resection of Gallbladder, Percutaneous Endoscopic Approach).
7Which fifth-character PCS approach value describes a procedure performed through a natural opening with percutaneous endoscopic assistance?
A.0, open exposure with endoscopic help
B.8, via natural opening endoscopic only
C.F, via natural or artificial opening with percutaneous endoscopic assistance
D.4, percutaneous endoscopic without natural-opening entry
Explanation: In the Medical and Surgical section, approach value F is Via Natural or Artificial Opening with Percutaneous Endoscopic Assistance. Approach 4 is percutaneous endoscopic, while 8 is natural-opening endoscopic without the additional percutaneous assistance.
8A patient undergoes a coronary artery bypass graft (CABG) using the left internal mammary artery (LIMA) to the left anterior descending artery (LAD). What is the correct ICD-10-PCS coding?
A.02100Z9
B.021109W
C.02100AW
D.02100Z8
Explanation: A LIMA-to-LAD CABG is coded 02100Z9 (Bypass Coronary Artery, One Artery, from Left Internal Mammary, Open Approach). Because the left internal mammary artery is left in situ as a pedicled graft (it is not detached and re-implanted), no graft material is taken, so the device value is Z (No Device); the qualifier 9 identifies the source vessel, the Left Internal Mammary. A device value would be coded only when separate graft material (e.g., autologous vein) is used.
9An established patient is seen in the office. Using 2021+ CPT guidelines, code selection is based on medical decision making (MDM) of low complexity. Which CPT code range applies and which level is appropriate?
A.99211-99215; 99213 for low MDM
B.99202-99205; 99203 for low MDM
C.99241-99245; 99243 for low MDM
D.99381-99397; 99393 for low MDM
Explanation: Established office/outpatient E/M codes are 99211-99215. For visits with a physician or other qualified professional, 99213 corresponds to low MDM; qualifying total time is an alternative selection method. 99211 has a distinct descriptor and does not use the same MDM framework.
10Which modifier indicates the left side of the body in a procedure claim?
A.Modifier 50
B.Modifier LT
C.Modifier RT
D.Modifier 51
Explanation: Modifier LT is used to indicate that a procedure was performed on the left side of the body. Modifier RT indicates the right side. Modifier 50 indicates a bilateral procedure, and Modifier 51 indicates multiple procedures performed during the same session.

CCS: Suggested Study Strategy

1Use 2026 code books for current CCS testing after May 1, 2026 and practice with the same books you will bring to Pearson VUE.
2Build separate workflows for ICD-10-CM diagnosis coding, ICD-10-PCS inpatient procedure coding, CPT/HCPCS outpatient coding, and medical-scenario abstraction.
3Study principal/first-listed diagnosis, procedure sequencing, POA, MCC/CC, and DRG/APC methodology as connected decisions rather than isolated terms.
4Use compliant query practice to separate missing documentation, conflicting documentation, uncertain diagnosis, and leading-query traps.
5Review HIPAA, AHIMA ethical coding standards, UHDDS, PSIs, HACs, NCCI, medical necessity, payer rules, and audit defensibility.
6Practice encoder, grouper, CAC, EHR, and HITECH questions as workflow and data-quality questions, not software trivia.
7Run mixed inpatient, outpatient, and emergency department case sets because AHIMA splits medical scenarios evenly across those settings.
8Allow 235 minutes for testing and instructions in timed practice, plus five minutes for the agreement in the four-hour appointment; practice flagging and reviewing items.

Frequently Asked Questions

How many questions are on the CCS exam?

AHIMA lists the CCS exam as 107 total questions: 97 scored items and 10 pretest items. The CCS crosswalk breaks this into 79 scored multiple-choice items, 7 pretest multiple-choice items, 18 scored case-scenario items, and 3 pretest case-scenario items.

How long is the CCS exam?

The four-hour CCS appointment includes five minutes for the agreement and three hours 55 minutes for testing and instructions. Candidates can move back and forth between items after selecting an answer, flag items, and review items before submitting if time remains.

What score do I need to pass CCS?

The AHIMA CCS passing score is 300. The score is not the same thing as a simple raw percentage because AHIMA uses certification-exam scoring methods.

Can I take the CCS exam online with OnVUE?

No. Pearson VUE states RHIA, RHIT, CCA, CCS, and CCS-P are available in person at Pearson VUE Authorized Test Centers. OnVUE online delivery is listed for CHDA, CHPS, and CDIP only.

What code books do I need for CCS in 2026?

AHIMA states CCS exams delivered on or after May 1, 2026 require 2026 code books. Candidates who do not bring the correct required code books to the test center are not allowed to test and forfeit exam fees.

What are the current CCS domains?

The effective CCS outline has five domains: Coding Knowledge and Skills 39-41%, Coding Documentation 18-22%, Provider Queries 9-11%, Regulatory Compliance 18-22%, and Information Technologies 9-11%. Medical scenarios are split evenly across inpatient, outpatient, and emergency department scenarios.

What is the CCS retake policy?

AHIMA states unsuccessful CCS candidates must submit a new application and fee. Candidates must wait at least 30 days before the new application is approved, and AHIMA says it cannot waive retest periods due to test security policy.
