Complete ICD-10-CM coding and documentation guide for Calcification of the Aorta. Includes clinical validation requirements, documentation requirements, and coding pitfalls.

Also known as:

Related ICD-10 Code Ranges

Complete code families applicable to Calcification of the Aorta

I70.0-I70.9Primary Range

Atherosclerosis

This range includes codes for atherosclerosis, which is the primary condition associated with calcification of the aorta.

Chronic Ischemic Heart Disease

This range includes codes for coronary atherosclerosis, which may be relevant if coronary calcification is present.

Key Information: ICD-10 code for calcification of the aorta

Essential facts and insights about Calcification of the Aorta

The ICD-10 code for calcification of the aorta is I70.0, which includes atherosclerosis of the aorta.

Primary ICD-10-CM Code for calcification of the aorta

Atherosclerosis of aorta
Billable Code

Decision Criteria

clinical Criteria

  • Presence of calcific deposits in the aorta on imaging

documentation Criteria

  • Detailed description of plaque composition and impact on blood flow

Applicable To

  • Calcification of the aorta

Excludes

  • Atherosclerosis of coronary arteries (I25.1-)

Clinical Validation Requirements

  • CT or MRI showing calcific deposits in the aortic wall
  • Agatston score >100
  • Commissural calcification on non-contrast CT

Code-Specific Risks

  • Confusing with non-atherosclerotic calcification

Coding Notes

  • Ensure documentation specifies atherosclerotic origin to avoid misclassification.

Ancillary Codes

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

Hyperlipidemia

E78.5
Use when hyperlipidemia is present alongside aortic calcification.

Hypertension

I10
Use when hypertension is documented with aortic calcification.

Differential Codes

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

Coronary atherosclerosis due to calcified coronary lesion

I25.84
Use if calcification is isolated to coronary arteries with aortic involvement.

Documentation & Coding Risks

Avoid these common documentation and coding issues when documenting Calcification of the Aorta to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code I70.0.

Impact

Clinical: Inadequate information for treatment planning., Regulatory: Non-compliance with documentation standards., Financial: Potential for claim denials.

Mitigation Strategy

Use structured reporting templates, Ensure all imaging findings are documented

Impact

Reimbursement: Incorrect coding can lead to denied claims., Compliance: Non-compliance with ICD-10 coding guidelines., Data Quality: Inaccurate clinical data affecting patient care.

Mitigation Strategy

Use I70.0 for aortic calcification to avoid misclassification.

Impact

Inaccurate or incomplete documentation of aortic calcification.

Mitigation Strategy

Use detailed templates and ensure all imaging findings are recorded.

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.

Documentation Templates for Calcification of the Aorta

Use these documentation templates to ensure complete and accurate documentation for Calcification of the Aorta. These templates include all required elements for proper coding and billing.

Aortic calcification with imaging findings

Specialty: Cardiology

Required Elements

  • Imaging specifics
  • Functional impact
  • Plaque composition

Example Documentation

Non-contrast CT demonstrates circumferential calcification of the thoracic aorta with Agatston score of 387.

Examples: Poor vs. Good Documentation

Poor Documentation Example
Aortic calcification noted on CT.
Good Documentation Example
Contrast-enhanced CT reveals extensive calcified atherosclerotic plaque in the descending thoracic aorta (Agatston score 387) causing 40% luminal stenosis.
Explanation
The good example provides specific imaging findings and clinical impact, which are necessary for accurate coding.
