Key Information: ICD-10 code for cerebral arteriosclerosis

Essential facts and insights about Cerebral Arteriosclerosis

The ICD-10 code for cerebral arteriosclerosis is I67.2, used when there is no acute infarction.

Primary ICD-10-CM Code for cerebral arteriosclerosis

Cerebral atherosclerosis
Billable Code

Decision Criteria

clinical Criteria

  • Presence of cerebral vessel stenosis on imaging

documentation Criteria

  • Symptoms linked to specific vascular territory

Applicable To

  • Cerebral arteriosclerosis

Excludes

  • Cerebral infarction (I63.-)

Clinical Validation Requirements

  • Imaging evidence of cerebral vessel stenosis
  • Clinical symptoms correlating with vascular territory

Code-Specific Risks

  • Incorrectly coding with I63.- without causal link

Coding Notes

  • Ensure documentation specifies the artery involved and any symptoms directly linked to arteriosclerosis.

Ancillary Codes

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

Sequelae of other cerebrovascular disease

I69.8
Use for documenting residual deficits from prior arteriosclerosis-related stroke.

Differential Codes

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

Cerebral infarction, unspecified

I63.9
Use I63.9 when there is an acute infarction due to arteriosclerosis.

Documentation & Coding Risks

Avoid these common documentation and coding issues when documenting Cerebral Arteriosclerosis to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code I67.2.

Impact

Clinical: Misrepresentation of patient condition, Regulatory: Potential audit issues, Financial: Claim denials or reduced reimbursement

Mitigation Strategy

Ensure clear documentation of causal relationships, Use templates that prompt for necessary details

Impact

Reimbursement: Denial of claims due to incorrect coding, Compliance: Non-compliance with coding guidelines, Data Quality: Inaccurate clinical data representation

Mitigation Strategy

Ensure documentation explicitly links arteriosclerosis to the stroke mechanism.

Impact

Failure to document the link between arteriosclerosis and stroke can lead to audit findings.

Mitigation Strategy

Use structured templates and provider queries to ensure complete documentation.

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 Cerebral Arteriosclerosis, with expert answers to help guide accurate code selection and documentation.

Documentation Templates for Cerebral Arteriosclerosis

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

Neurology Progress Note

Specialty: Neurology

Required Elements

  • Subjective symptoms
  • Objective findings
  • Assessment and plan

Example Documentation

**Subjective**: 'Worsening word-finding difficulty x2 weeks, no focal weakness' **Objective**: BP 142/88, LDL 158 mg/dL CTA: 75% stenosis left MCA, no acute infarct **Assessment**: 1. Symptomatic cerebral arteriosclerosis, left MCA (I67.2) 2. Dyslipidemia (E78.5) **Plan**: Start high-intensity statin, Schedule TCD with vasomotor reactivity testing

Examples: Poor vs. Good Documentation

Poor Documentation Example
Brain artery hardening with headache
Good Documentation Example
CT angiography shows 80% stenosis of right internal carotid artery causing transient left arm numbness
Explanation
The good example specifies the artery involved and links symptoms to the condition.
