Mitigation Strategy
Query provider to confirm chronic cystitis diagnosis.
Impact
Incomplete documentation of chronic cystitis can lead to audit findings.
Mitigation Strategy
Ensure all diagnostic criteria and chronicity are documented.
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.
