CHA Healthcare Auditor study plan

CHA Healthcare Auditor · Give each week a clear focus.

8 weeks · About 7 hours per week

Week 1

Healthcare Compliance and Regulatory Environment

  • Map the major federal healthcare compliance frameworks (False Claims Act, Anti-Kickback Statute, Stark, Civil Monetary Penalties) to the audit activities each one drives

  • Outline the structure of CMS Conditions of Participation and how they intersect with payer billing rules

  • Build a one-page reference chart of regulatory bodies (OIG, CMS, OCR, DOJ) and each one's enforcement role

  • Summarize the seven elements of an effective compliance program and state how an internal auditor tests each element

Your checkpoint

A two-page regulatory framework matrix covering at least 10 laws/regulators with the audit implication for each

Week 2

Healthcare Compliance and Regulatory Environment & Revenue Cycle and Billing/Coding Compliance Auditing

  • Trace how a regulatory requirement converts into a billing or coding control an auditor can test

  • Differentiate prospective vs. retrospective billing audits and select the appropriate approach for a given scenario

  • Explain the purpose and structure of a baseline billing audit and a focused medical record review

  • Identify the documentation elements a claim must support under medical necessity standards

Your checkpoint

A written audit scenario analysis (500+ words) selecting an audit approach for a hypothetical overpayment concern and justifying it

Week 3

Revenue Cycle and Billing/Coding Compliance Auditing

  • Deconstruct the revenue cycle stages from scheduling through collections and name the control point at each stage

  • Apply E/M leveling and key coding conventions to determine whether a documented encounter supports the billed code

  • Calculate an overpayment and error rate from a provided sample of coded claims

  • Distinguish upcoding, unbundling, and duplicate billing and match each to a detection method

Your checkpoint

A completed claim review worksheet for 15 sample encounters with code-level findings, error rate, and overpayment total

Week 4

Audit Planning, Risk Assessment, and Scoping & Audit Evidence, Testing Methodologies, and Sampling

  • Draft a risk assessment that ranks auditable areas by likelihood and impact

  • Convert audit objectives into testable procedures and assign evidence sources to each procedure

  • Design a sampling plan (attribute vs. variable) and justify sample size and selection method

  • Classify evidence by reliability and identify the documentation needed to support a finding

Your checkpoint

A complete audit plan for a mock engagement including scope, objectives, risk ranking, procedures, and sampling rationale

Week 5

Audit Evidence, Testing Methodologies, and Sampling & Clinical Documentation and Quality-of-Care Auditing

  • Execute a walkthrough and document the control flow for a billing process end to end

  • Evaluate clinical documentation for medical necessity, specificity, and support of the billed services

  • Compare documentation quality findings against quality-of-care indicators and flag discrepancies

  • Write workpaper entries that link each test result to evidence and to the audit objective

Your checkpoint

A set of workpapers for a mock clinical documentation review with evidence references and a preliminary findings list

Week 6

Internal Audit Standards, Ethics, and Professional Practice & Privacy, Security, and Health Information Management (HIPAA)

  • Apply the IIA Code of Ethics and Standards to resolve at least three auditor-independence or objectivity dilemmas

  • Map HIPAA Privacy, Security, and Breach Notification Rule requirements to specific audit tests

  • Identify minimum necessary, access control, and audit-log requirements and describe how to test each

  • Explain how protected health information handling affects audit sampling, storage, and reporting

Your checkpoint

A HIPAA audit test matrix mapping at least 10 requirements to test procedures, plus a written ethics case response

Week 7

Fraud, Waste, Abuse, and Investigative Auditing & Audit Reporting, Communication, and Follow-Up

  • Differentiate fraud, waste, and abuse and identify red flags that warrant an investigative referral

  • Outline the steps of an investigative audit, including evidence preservation and chain of custody

  • Structure an audit report with criteria, condition, cause, effect, and recommendation

  • Draft a finding and a management response request that survive a challenge to accuracy and tone

Your checkpoint

A full draft audit report on a mock fraud-adjacent finding, including a red-flag analysis and recommendation section

Week 8

Revenue Cycle and Billing/Coding Compliance Auditing & Audit Reporting, Communication, and Follow-Up & Fraud, Waste, Abuse, and Investigative Auditing

  • Re-test weak areas from prior weeks with timed practice items across all nine domains

  • Revise the mock report after simulated management pushback and document the follow-up plan

  • Build a corrective-action tracker that assigns owners, due dates, and verification methods

  • Consolidate the highest-risk concepts into a one-page personal review sheet

Your checkpoint

A final integrated capstone packet: revised report, follow-up tracker, and scored practice results by domain

Milestones

Week 2: Can explain, without notes, how at least five regulations translate into testable billing controls

Week 4: Produces a defensible audit plan with sampling rationale in under 90 minutes

Week 6: Scores 75% or higher on a mixed-domain practice set covering domains 1-4 and 7

Week 8: Scores 80% or higher on a full-length timed practice exam with no domain below 70%
