ICD-10 Coding for Carotid Aneurysm(I72.0)

Complete ICD-10-CM coding and documentation guide for Carotid Aneurysm. Includes clinical validation requirements, documentation requirements, and coding pitfalls.

Also known as:

Extracranial Carotid AneurysmInternal Carotid Artery Aneurysm

Related ICD-10 Code Ranges

Complete code families applicable to Carotid Aneurysm

I72.0-I72.9Primary Range

Aneurysm and dissection of other arteries

This range includes codes for aneurysms in arteries other than the aorta, including the carotid arteries.

Cerebral aneurysm, nonruptured

Used for intracranial aneurysms, which are distinct from precerebral carotid aneurysms.

Dissection of other arteries

Used for arterial dissections, which can be confused with aneurysms.

Key Information: ICD-10 code for carotid aneurysm

Essential facts and insights about Carotid Aneurysm

The ICD-10 code for a precerebral carotid aneurysm is I72.0. Use I67.1 for intracranial aneurysms.

Billable Code

Decision Criteria

clinical Criteria

  • Aneurysm located below the skull base

coding Criteria

  • Documentation specifies 'precerebral' location

Applicable To

  • Precerebral carotid aneurysm

Excludes

  • Cerebral aneurysm (I67.1)
  • Dissection of carotid artery (I77.71)

Clinical Validation Requirements

  • Imaging confirmation via CTA or MRA
  • Documentation of aneurysm location relative to skull base

Code-Specific Risks

  • Misclassification of intracranial aneurysms as I72.0

Coding Notes

  • Ensure precise documentation of the aneurysm's location to avoid coding errors.

Ancillary Codes

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

Occlusion and stenosis of carotid artery

I65.2
Use when there is concurrent stenosis or occlusion with the aneurysm.

Differential Codes

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

Cerebral aneurysm, nonruptured

I67.1
Use when the aneurysm is located in the intracranial portion of the carotid artery.

Dissection of other arteries

I77.71
Use for dissections, not aneurysms.

Documentation & Coding Risks

Avoid these common documentation and coding issues when documenting Carotid Aneurysm to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code I72.0.

Impact

Clinical: May lead to inappropriate treatment decisions., Regulatory: Increases risk of audit and compliance issues., Financial: Potential for incorrect billing and reimbursement.

Mitigation Strategy

Use structured templates for documentation., Ensure radiology reports include precise location.

Impact

Reimbursement: Incorrect DRG assignment may affect reimbursement., Compliance: Inaccurate coding could lead to compliance issues., Data Quality: Misclassification affects data accuracy and quality.

Mitigation Strategy

Verify the aneurysm's location with imaging and documentation.

Impact

Inadequate documentation of aneurysm location increases audit risk.

Mitigation Strategy

Implement mandatory documentation fields for location in EHR systems.

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.

Carotid Aneurysm Evaluation

Specialty: Neurology

Required Elements

  • Patient history
  • Imaging findings
  • Aneurysm location
  • Treatment plan

Example Documentation

62M with pulsatile R neck mass. CTA shows 3.1 cm saccular aneurysm at R ICA bifurcation.

Examples: Poor vs. Good Documentation

Poor Documentation Example
Carotid aneurysm noted.
Good Documentation Example
Saccular aneurysm at right ICA bifurcation with calcified plaque.
Explanation
The good example provides specific location and characteristics, aiding accurate coding.
