CCS Exam 2026-2027 - Certified Coding Specialist Assessment
Questions with Rationales, Exams of Medical Physics
Comprehensive Assessment
2026-2027 | 100 Questions | 100% VERIFIED
Introduction
This comprehensive assessment bank is designed to evaluate readiness for professional
certification and effective health information management execution. It emphasizes code
selection accuracy, documentation integrity, reimbursement logic, and compliant revenue
operations across inpatient, outpatient, and physician settings.
Content is organized across eight key domains: ICD-10-CM and ICD-10-PCS Coding; CPT and
HCPCS Level II Application; Healthcare Data Management and Quality; Reimbursement
Methodologies and Payer Systems; Compliance, Auditing, and Regulatory Guidelines;
Anatomy, Physiology, and Pathophysiology; Health Information Technology and EHR
Systems; and Revenue Cycle Management and Operations.
Each item tests application of professional judgment, guideline-based reasoning, and
system-level understanding essential for certification and high-quality coding and revenue
execution.
Question 1: A patient is seen in the emergency department for a displaced fracture of the
right radius after a fall. Which seventh character for the fracture code best reflects this
encounter?
A. D for subsequent encounter after active treatment has concluded
B. G for subsequent encounter with delayed healing without active care
C. A for initial encounter while receiving active treatment for the injury
D. S for sequela representing a late effect of a healed injury
Correct Answer: C - A for initial encounter while receiving active treatment for the
injury
Rationale: Seventh character A reports active treatment during the initial encounter. D and
G apply to aftercare phases, while S reports late effects, none of which fit active emergency
care.
Question 2: An inpatient is admitted with chest pain and found to have acute ST-elevation
myocardial infarction treated with percutaneous intervention. Which diagnosis is reported
as principal under UHDDS?
A. Hypertension because it was documented as a coexisting condition
B. Acute ST-elevation myocardial infarction as the condition chiefly responsible for
admission after study
C. Coronary atherosclerosis alone because it is the chronic underlying cause
D. Chest pain as the principal diagnosis because it was the admitting symptom
,Correct Answer: B - Acute ST-elevation myocardial infarction as the condition chiefly
responsible for admission after study
Rationale: Principal diagnosis is the condition established after study as chiefly responsible
for admission, here the infarction. Symptoms, chronic causes alone, and unrelated
comorbidities do not take precedence.
Question 3: Documentation states bilateral primary osteoarthritis of the knees with equal
severity. Which coding approach best captures laterality?
A. Assign a single bilateral code when the classification provides a bilateral option
B. Assign only a right-side code and omit the left side entirely
C. Assign an unspecified-side code despite documented bilaterality
D. Assign two identical unspecified codes to count both knees
Correct Answer: A - Assign a single bilateral code when the classification provides a
bilateral option
Rationale: Bilateral codes fully capture both sides in one code. Single-side, unspecified
despite detail, and duplicate unspecified codes lose specificity and accuracy.
Question 4: A patient has type 2 diabetes mellitus with diabetic chronic kidney disease
stage 3 and long-term insulin use. Which coding sequence best reflects this case?
A. E10.22 for type 1 diabetes without stage or insulin codes
B. N18.3 alone without any diabetes code or insulin code
C. E11.22 for type 2 diabetes with chronic kidney disease plus N18.3 for stage 3 and Z79.4
for long-term insulin use
D. E11.9 for uncomplicated diabetes alone without complication codes
Correct Answer: C - E11.22 for type 2 diabetes with chronic kidney disease plus N18.3
for stage 3 and Z79.4 for long-term insulin use
Rationale: Combination code E11.22 plus stage and insulin codes captures type,
complication, severity, and therapy. Wrong type, uncomplicated-only, and kidney-only
coding omit required detail.
Question 5: A patient has hypertension with stage 4 chronic kidney disease and heart
failure. Which code combination best applies?
A. N18.4 alone without any hypertension or heart disease codes
B. I10 for essential hypertension alone without heart or kidney linkage
C. I13.0 for hypertensive heart and chronic kidney disease with heart failure plus N18.4 and
an additional heart failure code
D. I50.9 for heart failure alone without hypertension or kidney codes
Correct Answer: C - I13.0 for hypertensive heart and chronic kidney disease with
heart failure plus N18.4 and an additional heart failure code
Rationale: Category I13 links hypertension with both heart and kidney disease, requiring
stage and heart failure codes. Isolated I10, kidney-only, and heart-failure-only coding break
combination rules.
, Question 6: An adult meets sepsis criteria with acute organ dysfunction due to E. coli
urinary infection. Which sequencing best reports severe sepsis?
A. N39.0 for urinary infection alone without sepsis or dysfunction codes
B. R65.20 alone as principal without the underlying sepsis code
C. A41.9 for unspecified sepsis alone without organism or severity detail
D. A41.51 for E. coli sepsis first followed by R65.20 for severe sepsis without septic shock
plus organ dysfunction and infection codes
Correct Answer: D - A41.51 for E. coli sepsis first followed by R65.20 for severe sepsis
without septic shock plus organ dysfunction and infection codes
Rationale: Severe sepsis requires the sepsis code first with R65.2 second plus dysfunction
codes. R65.2 alone, infection-only, and unspecified-only coding omit required sequencing
and specificity.
Question 7: A coder captures homelessness and unemployment affecting a diabetic
patient's management. Which Z-code range best reports these social determinants?
A. Z55-Z65 for persons with potential health hazards related to socioeconomic and
psychosocial circumstances
B. Z00-Z01 for general examinations without social context
C. Z30-Z39 for pregnancy and reproductive management only
D. Z80-Z87 for family and personal history of disease
Correct Answer: A - Z55-Z65 for persons with potential health hazards related to
socioeconomic and psychosocial circumstances
Rationale: Z55-Z65 reports socioeconomic factors influencing care. Examination,
pregnancy-only, and history categories do not capture housing or employment
determinants.
Question 8: A cyclist is injured in a collision with a motor vehicle on a public road. Which
external cause coding approach best supplements the injury codes?
A. Omit external cause codes because injury codes alone are sufficient
B. Assign V00-Y99 codes for transport mechanism, place of occurrence, and activity when
documented
C. Assign a procedure code in place of external cause codes
D. Assign only a Z code for examination without mechanism detail
Correct Answer: B - Assign V00-Y99 codes for transport mechanism, place of
occurrence, and activity when documented
Rationale: External cause codes add mechanism, place, and activity context to injuries.
Omission, examination-only, and procedure substitution lose required supplemental detail.
Question 9: A coder builds an ICD-10-PCS code for a procedure. Which seven-character
structure best reflects the system design?
A. Category, etiology, anatomic site, severity, laterality, encounter, and status
B. Section, body system, root operation, body part, approach, device, and qualifier
C. Revenue code, charge amount, date, payer, modifier, units, and tax ID
