CASCC study plan
CASCC · Give each week a clear focus.
8 weeks · About 7 hours per week
Coding Guidelines and Regulatory Compliance & Surgical Coding (Integumentary, Musculoskeletal, and Related Systems)
Map each CASCC domain to its exam weight and rank your personal weak areas
Outline the current-year CPT, ICD-10-CM, and CPT Assistant guidance hierarchy for coding compliance questions
Build a one-page reference of integumentary coding rules (excision sizing, lesion margins, repair classification)
Work through 40 integumentary coding scenarios and record error patterns
Your checkpoint
A one-page integumentary quick-reference sheet plus a scored log of 40 practice scenarios with each error tagged to a rule
Surgical Coding (Integumentary, Musculoskeletal, and Related Systems)
Distinguish musculoskeletal coding rules for fracture care, arthroscopy, and joint replacement
Apply modifier and add-on code logic to musculoskeletal case vignettes
Compare integumentary versus musculoskeletal coding decision trees using self-written vignettes
Complete 50 mixed surgical coding scenarios under timed conditions
Your checkpoint
A 50-question timed surgical coding set scored at 80% or higher, with a written rationale for every missed item
Modifiers and Coding Accuracy & Coding Guidelines and Regulatory Compliance
Categorize all modifier groups (E/M, surgical, anesthesia, radiology, lab) and state when each applies
Draft five original vignettes that each require a different modifier and justify the choice
Identify common compliance pitfalls (medical necessity, unbundling, documentation support)
Audit ten practice claims for modifier and compliance errors
Your checkpoint
A modifier decision matrix plus a ten-claim audit report listing each error found and the corrective modifier or documentation fix
Anesthesia and Pain Management Coding & Pathology and Laboratory Coding
Explain anesthesia coding elements: base units, time reporting, physical status modifiers, qualifying circumstances
Calculate anesthesia units for ten original scenarios
Outline pathology and laboratory coding rules for specimen handling, panels, and organ versus disease coding
Differentiate clinical lab panels from individual tests in five vignettes
Your checkpoint
A unit-calculation worksheet for ten anesthesia scenarios plus a five-vignette lab panel worksheet, both scored against your own written answer key
Radiology and Diagnostic Services Coding & Medicine and Ancillary Services Coding
Apply radiology coding rules for supervision levels, contrast, and laterality modifiers
Assign codes to ten original radiology vignettes
Outline medicine and ancillary service rules including injections, infusions, and diagnostic testing
Link E/M and ancillary service coding decisions to documentation requirements
Your checkpoint
A combined 20-question radiology and medicine practice set scored at 80% or higher with a written correction for each miss
Ambulatory Surgery Center Billing and Claims & Modifiers and Coding Accuracy
Outline ASC billing requirements: claim forms, facility versus professional components, and payer-specific edits
Trace a complete ASC claim from documentation to submission using a self-built flowchart
Apply modifiers to ASC claims where multiple procedures and bilateral services occur
Identify denial-prevention checks for ASC claims
Your checkpoint
A one-page ASC claim flow diagram annotated with the modifier and compliance checkpoints at each step
Coding Guidelines and Regulatory Compliance & Surgical Coding (Integumentary, Musculoskeletal, and Related Systems) & Anesthesia and Pain Management Coding & Radiology and Diagnostic Services Coding & Pathology and Laboratory Coding & Medicine and Ancillary Services Coding & Modifiers and Coding Accuracy & Ambulatory Surgery Center Billing and Claims
Assemble a 100-question cumulative practice exam weighted to match domain percentages
Complete the exam in two timed sittings
Categorize every missed item by domain and root cause
Re-study the two lowest-scoring domains using targeted drills
Your checkpoint
A scored 100-question cumulative exam with a domain-by-domain error analysis table identifying your two weakest domains
Coding Guidelines and Regulatory Compliance & Surgical Coding (Integumentary, Musculoskeletal, and Related Systems) & Modifiers and Coding Accuracy & Ambulatory Surgery Center Billing and Claims
Re-drill the two weakest domains until practice accuracy reaches 85%
Review all previously missed items from weeks 1 through 7
Complete a final timed 60-question mixed set emphasizing the highest-weight domains
Write a test-day strategy checklist covering timing, flagging, and guessing rules
Your checkpoint
A final 60-question timed set scored at 85% or higher plus a one-page test-day strategy checklist
Milestones
Week 2: Score 80% or higher on the 50-question surgical coding set and document a rationale for every miss.
Week 4: Correctly calculate anesthesia units on at least 8 of 10 scenarios and accurately classify 4 of 5 lab panel vignettes.
Week 6: Complete the ASC claim flow diagram with all modifier and compliance checkpoints annotated.
Week 8: Score 85% or higher on the final 60-question timed set and finish the test-day strategy checklist.
