What is the ICD-10 code for aortic valve insufficiency?

The ICD-10 code for nonrheumatic aortic valve insufficiency is I35.1, while rheumatic aortic insufficiency is coded as I06.1.

How do you code aortic valve insufficiency with a bicuspid valve?

For aortic valve insufficiency with a bicuspid valve, use I35.1 for the insufficiency and Q23.83 for the congenital bicuspid valve.

Code	Description	When to Use	Key Documentation
I35.1	Nonrheumatic aortic (valve) insufficiency	Use when aortic insufficiency is nonrheumatic and confirmed by echocardiographic criteria.	Echocardiographic evidence of regurgitant volume ≥60 mL/beat Vena contracta width ≥0.6 cm
I06.1	Rheumatic aortic insufficiency	Use when aortic insufficiency is due to rheumatic fever.	History of rheumatic fever Echocardiographic evidence consistent with rheumatic changes

Documentation & Coding Risks

Avoid these common issues when documenting Aortic Valve Insufficiency.

Lack of severity documentation

Impact

Clinical: Inadequate treatment planning., Regulatory: Non-compliance with coding standards., Financial: Potential reimbursement issues.

Mitigation

Use structured templates, Include quantitative metrics

Coding nonrheumatic AR as rheumatic

Impact

Reimbursement: Incorrect DRG assignment may affect reimbursement., Compliance: Non-compliance with coding guidelines., Data Quality: Inaccurate clinical data affecting patient records.

Mitigation

Verify etiology through patient history and documentation.

Omitting Q23.83 when bicuspid valve is present

Impact

Reimbursement: Potential under-coding affecting reimbursement., Compliance: Failure to capture complete clinical picture., Data Quality: Incomplete patient records.

Mitigation

Ensure congenital conditions are coded when documented.

Etiology Documentation

Impact

Inadequate documentation of AR etiology.

Mitigation

Ensure detailed history and echocardiographic findings are documented.
