Use specific language and test scores., Ensure comprehensive workup is documented.
Impact
Reimbursement: Potential for lower reimbursement if specificity is not documented., Compliance: Risk of non-compliance with coding guidelines., Data Quality: Impacts accuracy of patient records.
Mitigation Strategy
Ensure provider explicitly documents 'mild cognitive impairment' for G31.84.
Impact
High risk of audits if R41.9 is used without ruling out specific conditions.
Mitigation Strategy
Document comprehensive assessments and exclusions.
Documentation errors, coding pitfalls, and audit risks are interconnected aspects of medical coding and billing. Addressing all three areas helps ensure accurate coding, optimal reimbursement, and regulatory compliance.
