Decision Criteria
clinical Criteria
- D-dimer level is elevated without a confirmed underlying condition.
coding Criteria
- No other ICD-10 code better describes the patient's condition.
Applicable To
- Elevated D-dimer
Excludes
- Conditions with a known cause of elevated D-dimer, such as DVT or PE
Clinical Validation Requirements
- Documented D-dimer level above the normal reference range
- Absence of a confirmed underlying condition causing the elevation
Code-Specific Risks
- Incorrectly using this code when an underlying condition is present
Coding Notes
- Ensure documentation supports the use of R79.89 by excluding other causes.

I82.4-Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting Elevated D-dimer to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code R79.89.
Impact
Clinical: May lead to incorrect clinical decisions., Regulatory: Non-compliance with documentation standards., Financial: Potential for claim denials due to insufficient documentation.
Mitigation Strategy
Ensure lab results are included in the patient's record., Verify documentation before submission.
Impact
Reimbursement: Incorrect coding may lead to claim denials., Compliance: Non-compliance with coding guidelines., Data Quality: Inaccurate clinical data representation.
Mitigation Strategy
Use R79.89 for elevated D-dimer unless CEA is also elevated.
Impact
Using R79.89 without proper documentation of D-dimer levels.
Mitigation Strategy
Ensure all lab values are documented and linked to clinical decisions.
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.
