Complete code families applicable to Thrombectomy

I74-I74.9Primary Range

Arterial embolism and thrombosis

This range covers conditions related to arterial thrombosis, which are primary scenarios for thrombectomy procedures.

Other venous embolism and thrombosis

This range includes venous thrombosis conditions, relevant for venous thrombectomy procedures.

Key Information: ICD-10 code for thrombectomy

Essential facts and insights about Thrombectomy

The ICD-10 code for thrombectomy in cases of acute arterial occlusion of the lower extremities is I74.3.

Primary ICD-10-CM Code for thrombectomy

Embolism and thrombosis of arteries of the lower extremities
Billable Code

Decision Criteria

clinical Criteria

  • Presence of acute arterial occlusion confirmed by imaging

documentation Criteria

  • Detailed operative note including access site and device used

Applicable To

  • Acute embolism and thrombosis of arteries of lower extremities

Excludes

  • Chronic embolism and thrombosis of arteries of lower extremities

Clinical Validation Requirements

  • Pre-procedure imaging confirming arterial occlusion
  • Operative note detailing thrombectomy procedure

Code-Specific Risks

  • Misclassification as chronic condition
  • Omission of procedure details

Coding Notes

  • Ensure documentation specifies acute nature and location of thrombosis.

Ancillary Codes

Additional codes that should be used in conjunction with the main diagnosis codes when applicable.

Long term (current) use of anticoagulants

Z79.01
Use to indicate ongoing anticoagulation therapy post-thrombectomy.

Differential Codes

Alternative codes to consider when ruling out similar conditions to the primary diagnosis.

Acute embolism and thrombosis of deep veins of lower extremity

I82.4
Use for venous thrombosis requiring thrombectomy, not arterial.

Documentation & Coding Risks

Avoid these common documentation and coding issues when documenting Thrombectomy to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code I74.3.

Impact

Clinical: Inadequate clinical records, Regulatory: Non-compliance with documentation standards, Financial: Potential claim denials

Mitigation Strategy

Use standardized templates, Ensure thorough operative notes

Impact

Reimbursement: Potential denial of claims due to incorrect coding, Compliance: Non-compliance with coding standards, Data Quality: Inaccurate clinical data affecting patient records

Mitigation Strategy

Verify acute nature through imaging and clinical presentation.

Impact

Inadequate documentation of thrombectomy procedures can lead to audit issues.

Mitigation Strategy

Implement comprehensive documentation templates and regular audits.

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.

Frequently Asked Questions

Common questions about ICD-10 coding for Thrombectomy, with expert answers to help guide accurate code selection and documentation.

Documentation Templates for Thrombectomy

Use these documentation templates to ensure complete and accurate documentation for Thrombectomy. These templates include all required elements for proper coding and billing.

Acute Limb Ischemia

Specialty: Vascular Surgery

Required Elements

  • Access site
  • Device used
  • Number of passes
  • Outcome

Example Documentation

**Thrombectomy Procedure Note** - Access: Ultrasound-guided right common femoral access - Findings: 5cm thrombus in mid-SFA with TIMI 0 flow - Device: 6F Penumbra CAT5 catheter - Passes: 3 complete passes - Adjuncts: tPA 4mg intra-arterial bolus - Outcome: TICI 2b flow achieved - Complications: No distal embolization noted

Examples: Poor vs. Good Documentation

Poor Documentation Example
Thrombectomy done with good result
Good Documentation Example
37184: Mechanical thrombectomy of right EIA using 8F sheath and Inari FlowTriever®. 3 device passes with 4cm thrombus extracted. Final angiogram shows TIMI 3 flow.
Explanation
The good example provides specific details on the procedure, including device and outcome, which are necessary for accurate coding and billing.
