Use R35.8 for polyuria when urine output exceeds 3L/day.
Impact
Using R35.0 when an underlying condition is present.
Mitigation Strategy
Ensure thorough review of patient history and test results.
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.
