Mitigation Strategy
Educate providers on the importance of specifying CKD stage., Implement documentation templates that prompt for stage.
Impact
Reimbursement: May lead to incorrect reimbursement if underlying conditions are not coded., Compliance: Non-compliance with ICD-10 coding guidelines., Data Quality: Inaccurate data representation of patient conditions.
Mitigation Strategy
Always include additional codes for underlying conditions like diabetes or hypertension.
Impact
Missing eGFR values or stage specification.
Mitigation Strategy
Use templates and checklists to ensure all required information is 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.
