| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| R79.9 | Abnormal finding of blood chemistry, unspecified | Use when lab results indicate abnormal blood chemistry and no specific diagnosis is documented. |
|
| Z01.83 | Encounter for blood typing | Use when the patient is seen specifically for blood typing. |

Clinical Decision Support
Always review the patient's clinical documentation thoroughly. When in doubt, choose the more specific code and ensure documentation supports it.

Essential facts and insights about Laboratory Tests
Primary ICD-10-CM Codes for labs
Decision Criteria
clinical Criteria
- Presence of abnormal lab results without a specific diagnosis
Applicable To
- Abnormal blood chemistry
Excludes
- Specific abnormal findings (e.g., hyperglycemia, hyperlipidemia)
Clinical Validation Requirements
- Lab results showing abnormal blood chemistry without a definitive diagnosis
Code-Specific Risks
- Overuse of unspecified codes can lead to audit risks.
Coding Notes
- Ensure lab results are documented clearly to support the use of this code.
Z01.83 - Encounter for blood typing
Use when the patient is seen specifically for blood typing.
Applicable To
- Blood typing
Clinical Validation Requirements
- Documentation of encounter specifically for blood typing
Coding Notes
Document the purpose of the encounter clearly as blood typing.
Ancillary Codes
Additional codes that should be used in conjunction with the main diagnosis codes when applicable.

Z01.83Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting Laboratory Tests to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code R79.9.
Impact
Clinical: May lead to misinterpretation of patient condition., Regulatory: Increases risk of non-compliance with coding standards., Financial: Potential for denied claims due to lack of specificity.
Mitigation Strategy
Always document specific lab values and any clinical interpretation., Use specific codes when available.
Impact
Reimbursement: May lead to denied claims due to lack of specificity., Compliance: Increases risk of audits and compliance issues., Data Quality: Reduces the quality of clinical data for patient management.
Mitigation Strategy
Ensure lab results are documented and specify the abnormality when possible.
Impact
High risk of audit when unspecified codes are used without supporting documentation.
Mitigation Strategy
Ensure all lab results are documented with specific values and interpretations.
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.
