Always include drug name and administration details in notes.
Impact
Reimbursement: Incorrect coding may lead to denied claims., Compliance: Non-compliance with coding guidelines., Data Quality: Inaccurate medical records.
Mitigation Strategy
Verify the drug was correctly administered and use T45.1X5A.
Impact
Reimbursement: May affect DRG assignment and reimbursement., Compliance: Non-compliance with ICD-10 guidelines., Data Quality: Inaccurate clinical data representation.
Mitigation Strategy
Always code the manifestation first, followed by T45.1X5A.
Impact
Manifestation codes must precede T codes.
Mitigation Strategy
Regular training on ICD-10 sequencing rules.
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.
