Experience the Quality With Free CCS Exam Questions That Helps Candidates Pass

ICD-10-CM requires coders to use “late effect” codes (I69.-) for sequelae of cerebrovascular disease. In this case, right hemiplegia is a sequela of CVA. Option A misses the complication. Option B does not capture etiology. Option C incorrectly uses a separate hemiplegia code. Correct coding is I63.9 (acute infarction) for current event and I69.351 to capture right hemiplegia due to infarction. This dual coding provides complete clinical picture and severity.

When progress notes and discharge summary conflict, coders must seek clarification. Only provider documentation in the final summary can confirm diagnoses. Querying ensures that exacerbation and bronchitis are appropriately captured if clinically valid. Coding COPD alone would lose severity. Coding exacerbation or bronchitis without clarification risks compliance. Queries preserve accuracy and audit defense.

Automatic logoff protects confidentiality by preventing unauthorized viewing of PHI when systems are left unattended. Integrity ensures accuracy, availability ensures access, and authentication verifies identity. Confidentiality safeguards reduce the risk of PHI exposure and support HIPAA compliance.

Encryption protects confidentiality, ensuring that PHI is unreadable to unauthorized users during transmission. Integrity prevents tampering, availability ensures access, and authentication verifies identity. Encryption is a HIPAA-required technical safeguard that reduces breach risks in HIM and coding operations.

Encryption protects PHI by transforming data into unreadable form during transmission, ensuring integrity and confidentiality. Audit trails log access but don’t protect data during transfer. Validation edits check data accuracy but not transmission security. Unique logins ensure accountability but don’t secure data in transit. HIPAA requires encryption (or equivalent safeguards) to mitigate interception risks during electronic exchange of coded health data.
