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

The ICD-10 code for non-rheumatic aortic valve endocarditis is I33.0, while rheumatic cases use I01.1. Prosthetic valve infections are coded as T82.6XXA.

How is prosthetic valve endocarditis coded?

Prosthetic valve endocarditis is coded with T82.6XXA, and requires additional organism codes from B95-B97 if known.

Code Comparison: When to Use Each Code

Compare key differences between these codes to ensure accurate selection

Code	Description	When to Use	Key Documentation
I01.1	Acute rheumatic endocarditis	Use when endocarditis is confirmed to be rheumatic in origin.	ASO titer elevation Evidence of recent streptococcal infection
I33.0	Acute and subacute infective endocarditis	Use for non-rheumatic infective endocarditis of the aortic valve.	Positive blood cultures Echocardiographic evidence of vegetations
T82.6XXA	Infection and inflammatory reaction due to cardiac valve prosthesis, initial encounter	Use for infections related to prosthetic aortic valves.	Evidence of infection on prosthetic valve Positive imaging findings

Documentation & Coding Risks

Avoid these common issues when documenting Aortic Valve Endocarditis.

Omitting organism code when known

Impact

Clinical: Incomplete clinical picture, Regulatory: Non-compliance with coding guidelines, Financial: Potential loss of reimbursement

Mitigation

Always include B95-B97 codes when organism is identified

Mixing rheumatic and non-rheumatic codes without proper documentation

Impact

Reimbursement: Incorrect DRG assignment leading to reimbursement issues, Compliance: Potential audit flags due to coding inconsistencies, Data Quality: Compromised data integrity affecting clinical outcomes

Mitigation

Ensure clear documentation of etiology before coding.

Prosthetic Valve Infection Coding

Impact

Incorrect use of T82.6XXA without supporting documentation

Mitigation

Ensure thorough documentation of prosthetic valve involvement and infection.
