Understanding IHSS and Insurance Implications
Key insight: IHSS insurability depends far more on demonstrating minimal symptoms, preserved heart function, and absent sudden death risk factors than on the diagnosis itself.
Hypertrophic subaortic stenosis (IHSS) occurs when the heart muscle, particularly the interventricular septum, becomes abnormally thickened. This thickening can obstruct blood flow from the left ventricle through the aortic valve during heart contraction, creating a pressure gradient. The condition is genetic, caused by mutations in genes encoding heart muscle proteins, and can range from asymptomatic with minimal obstruction to severely symptomatic with significant outflow obstruction and life-threatening arrhythmias.
For life insurance purposes, IHSS represents one of the more challenging cardiac conditions because it carries the risk of sudden cardiac death—even in relatively young, apparently healthy individuals with minimal symptoms. Insurance companies recognize that IHSS follows highly variable courses: some patients remain asymptomatic throughout normal lifespans with only mild disease requiring monitoring, while others develop progressive symptoms, heart failure, or experience sudden cardiac arrest despite treatment.
Underwriters must distinguish between applicants whose disease poses minimal mortality risk and those with features predicting serious complications. The evaluation centers on critical questions: disease severity markers, symptom status, arrhythmia history, family history, and treatment requirements.
Most Favorable Scenario
- Minimal septal hypertrophy
- No significant obstruction
- Asymptomatic status
- Normal heart function
- No arrhythmias detected
- No family sudden deaths
Moderate Concerns
- Mild to moderate hypertrophy
- Some obstruction present
- Mild symptoms with activity
- Preserved heart function
- On medical therapy
- No prior cardiac events
High Risk Factors
- Severe hypertrophy (>30mm)
- Significant obstruction present
- Symptomatic with activity
- Arrhythmias documented
- ICD implanted
- Family sudden deaths

Professional Insight
“We work with IHSS clients occasionally, and we’re always completely transparent about expectations—this is one of the most challenging cardiac conditions for life insurance approval. We’ve successfully secured Table 8 coverage for a client with mild non-obstructive disease, minimal septal thickness, normal ejection fraction, no symptoms, negative genetic testing, and no family history of sudden death. That represents about the best-case scenario possible. Most IHSS cases face decline from traditional carriers.”

How Insurance Companies Evaluate IHSS
Key insight: Underwriters employ an exceptionally rigorous approach, recognizing the condition’s potential for sudden cardiac death and the need to identify high-risk versus lower-risk presentations.
Insurance underwriters request comprehensive cardiac documentation when evaluating IHSS cases, recognizing the condition’s potential for sudden cardiac death and the need to identify high-risk versus lower-risk presentations.
| Critical Measurement | What Underwriters Assess | Impact on Approval |
|---|---|---|
| LVOT Gradient | Degree of obstruction (mmHg at rest and with provocation) | High – Primary severity indicator |
| Septal Thickness | Interventricular septum measurements via echo or MRI | High – Indicates disease severity |
| Ejection Fraction | Left ventricular pumping function percentage | High – Determines cardiac reserve |
| Symptoms/Function | Exercise tolerance, chest pain, syncope, dyspnea | High – Reflects real-world impact |
| Arrhythmia History | Holter monitoring, VT, VF, or AFib documentation | High – Major sudden death predictor |
| Family History | Relatives with IHSS or sudden cardiac deaths | High – Genetic risk assessment |
| Treatment Needs | Medications, procedures, or ICD implantation | Medium – Signals disease severity |
Important Underwriting Consideration
The presence of IHSS automatically places applicants in a high-risk category because the condition can cause sudden death without warning. However, well-documented cases showing mild non-obstructive disease without symptoms or high-risk features can sometimes achieve table-rated coverage. More severe or symptomatic cases typically face decline for traditional insurance.
Documents Required for Review
- Complete echocardiogram reports (multiple studies showing measurements over time)
- Cardiac MRI results, if performed, including hypertrophy distribution and scar imaging
- Holter monitor results documenting any arrhythmias
- Exercise stress test results showing function and blood pressure response
- Genetic testing result,s if available
- All cardiology consultation notes with risk assessments
- Current medication list and treatment history
- Family history documentatio,n including pedigree
Coverage Outlook by Disease Severity
Key insight: IHSS insurance prospects vary dramatically based on obstruction severity, symptoms, arrhythmia history, family history, and treatment requirements.
Life insurance prospects for IHSS vary dramatically based on disease characteristics and risk factors. Understanding where your situation falls helps establish realistic expectations for coverage possibilities.
Mild Non-Obstructive IHSS
Insurance Outlook: Most Favorable (Still Challenging)
Minimal septal hypertrophy (13-16 mm), no or minimal obstruction (gradient below 30 mmHg), asymptomatic status, normal ejection fraction, no arrhythmias on monitoring, and no family history of sudden cardiac death.
Moderate IHSS with Some Risk Features
Insurance Outlook: Challenging
Mild to moderate hypertrophy, mild obstruction, minimal symptoms with activity, preserved ejection fraction, on medical therapy, or with family history concerns.
Severe IHSS or Multiple Risk Features
Insurance Outlook: Very Challenging to Impossible
Significant hypertrophy (>20 mm), substantial obstruction (gradient >50 mmHg), symptomatic presentation, documented arrhythmias, family sudden death history, or ICD implantation.
Very Severe IHSS with Major Risk Factors
Insurance Outlook: Not Available Traditionally
ICD implanted, history of syncope or cardiac arrest, severe symptomatic disease, significant family history of sudden death, or reduced ejection fraction.

Key Underwriting Factors
Key insight: Beyond basic disease measurements, specific factors critically influence whether you receive any coverage offer and what premium rates apply for IHSS cases.
Sudden Death Risk Stratification
Underwriters focus intensely on features predicting sudden cardiac death: cardiac arrest or sustained ventricular tachycardia history, family history of sudden cardiac death, unexplained syncope episodes, non-sustained ventricular tachycardia on monitoring, abnormal blood pressure response during exercise, and massive left ventricular hypertrophy (above 30 mm). The presence of even one major risk factor dramatically worsens insurance prospects, while multiple risk factors typically result in immediate decline.
Functional Status Classification
New York Heart Association (NYHA) classification significantly impacts underwriting:
NYHA Class I
- No symptoms
- No limitation
- Most favorable for underwriting
NYHA Class II-III
- Mild to moderate symptoms
- Activity limitation present
- Creates substantial challenges
NYHA Class IV
- Symptoms at rest
- Severely limited
- Precludes coverage
Treatment Intensity and Response
The treatments required signal disease severity: no treatment (most favorable), beta-blockers or calcium channel blockers (indicates symptomatic disease), multiple medications (more significant disease), septal reduction procedures (severe obstruction requiring intervention), or ICD implantation (high sudden death risk—almost universally results in decline).
Family History Impact
Genetic inheritance means family history provides critical prognostic information. Favorable family history (relatives living normal lifespans with IHSS) provides reassurance. Unfavorable family history (sudden cardiac deaths in young relatives) dramatically worsens prospects as it suggests aggressive genetic variants with high mortality risk.
Optimal Timing for Applications
Key insight: Strategic application timing matters for IHSS cases, though even optimal timing may not overcome the diagnosis’s inherent severity in many situations.
Ideal Application Preparation
- Wait 12-24 months after diagnosis to demonstrate stability
- Accumulate multiple echocardiograms showing no progression
- Obtain multiple normal Holter monitors confirming no arrhythmias
- Complete normal stress test with appropriate blood pressure response
- Secure genetic testing results, if available, showingthe absence of high-risk mutations
- Document complete asymptomatic status with normal exercise tolerance
- Compile a comprehensive family history showing no sudden cardiac deaths
When to Apply
- After 12-24 months of documented stability
- When the disease is asymptomatic
- With serial normal testing results
- After stabilization, any treatment needed
When NOT to Apply
- Within 12 months of diagnosis
- After recent syncope episodes
- Following the ICD implantation
- During progressive worsening
- After recent procedures
Important Timing Considerations
Within 12 months of diagnosis, most carriers will undergo assessment to assess disease severity and stability. Recent ICD implantation almost universally results in a decline in traditional coverage. Syncope episodes are red flags indicating dangerous arrhythmias. Progressive symptoms or measurements indicate disease progression, warranting postponement. For most IHSS cases, even optimal timing doesn’t overcome the diagnosis’s severity—secure guaranteed issue coverage immediately rather than remaining uninsured while exploring traditional options.

Required Medical Documentation
Key insight: IHSS cases require exceptionally comprehensive cardiac documentation to provide underwriters with complete information about sudden death risk.
Essential Medical Records Required
- Complete echocardiogram reports (at least 2-3 over time) with septal thickness, gradient measurements, ejection fraction, and any abnormalities
- Cardiac MRI report if performed, including late gadolinium enhancement patterns and hypertrophy distribution
- Holter monitor results documenting any arrhythmias or ectopy
- Exercise stress test results showing functional capacity and blood pressure response
- Electrophysiology study results, if performed
- Genetic testing results, if available, will include specific mutations identified
- Complete cardiology consultation notes from all visits with risk stratification
- Family history documentation, including pedigree with sudden deaths and causes
- Current medication list with all cardiac drugs, doses, and duration
- Surgical or procedure reports if myectomy, ablation, or ICD implantation was performed
- Most recent cardiologist assessment with explicit sudden death risk stratification
Critical details within medical records that underwriters scrutinize include maximum septal thickness measurement, LVOT gradient measurements at rest and with provocation, complete arrhythmia documentation, exercise test blood pressure response patterns, and family history specifics, including ages at sudden death and confirmed causes.
Strategies to Improve Your Application
Key insight: While IHSS presents exceptional challenges, certain strategic actions can help in rare favorable cases or maximize alternative coverage for typical cases.
For Mild Cases
- Compile multiple normal imaging studies
- Obtain an explicit low-risk statement from a cardiologist
- Document comprehensive stability over time
- Work with specialized high-risk cardiac brokers
- Apply to multiple carriers simultaneously
For All IHSS Cases
- Maximize employer group life insurance
- Secure a guaranteed issue immediately
- Don’t delay waiting for traditional options
- Pre-screen with specialists before formal applications
- Explore association and organizational group coverage
Success Strategy
For most IHSS cases, securing guaranteed issue coverage immediately makes more sense than wasting time on likely-declined traditional applications. Only pursue traditional options if you have genuinely mild disease characteristics. Work with specialized brokers who can pre-screen your case before formal submission, avoiding wasted declined applications on your record.
Alternative Coverage Options
Key insight: For most IHSS cases, alternative products provide the only realistic path to life insurance coverage.
Guaranteed Issue Life Insurance
No medical questions or exams required. Coverage is available regardless of cardiac disease severity. Typically $5,000-$25,000 face amounts. 2-3 year graded death benefit period applies.
Group Life Insurance
Employer-sponsored coverage with guaranteed issue for basic amounts. No medical underwriting applied. Consider group life insurance opportunities through employment, associations, or professional organizations.
Simplified Issue Life Insurance
Uses abbreviated health questionnaires without medical exams. Limited applicability for IHSS due to heart disease questions. Worth exploring for exceptionally mild cases only.
Final Expense Insurance
Smaller coverage amounts for immediate needs. More lenient underwriting standards. Supplementary option alongside other coverage.

Frequently Asked Questions
Can I get life insurance with IHSS (hypertrophic cardiomyopathy)?
Traditional life insurance for IHSS is extremely difficult, but not impossible in rare mild cases. Most carriers decline IHSS automatically due to the sudden death risk. The very best scenarios—minimal hypertrophy, no obstruction, asymptomatic, no arrhythmias, no family history—might achieve Table 6-10 ratings with specialty carriers. Any significant obstruction, symptoms, arrhythmias, family history concerns, or ICD placement typically results in decline. Most IHSS patients must rely on guaranteed issue and group coverage.
How long after an IHSS diagnosis should I wait to apply for life insurance?
Wait at least 12-24 months after diagnosis to accumulate stability documentation before considering traditional coverage. This allows multiple echocardiograms showing no progression, Holter monitors confirming no arrhythmias, and documentation of continued asymptomatic status. However, for most IHSS cases, waiting won’t overcome the diagnosis’s severity—traditional coverage often isn’t realistic regardless of timing. Secure guaranteed issue and group coverage immediately rather than remaining uninsured.
Will I automatically be declined for life insurance if I have an ICD for IHSS?
Yes, ICD implantation almost universally results in a decline in traditional life insurance. The ICD indicates a high sudden death risk based on multiple risk factors or previous cardiac arrest, which underwriters cannot overlook. Focus on guaranteed issue policies and maximizing group coverage through employment rather than pursuing traditional applications that will likely be declined.
Does a family history of sudden death from IHSS affect my life insurance application?
Yes, dramatically. Family history of sudden cardiac death from IHSS, particularly in young relatives or multiple family members, substantially increases your sudden death risk and typically results in traditional insurance decline even when your personal disease is mild. Underwriters view family history as one of the strongest sudden death predictors.
Can I get life insurance if my IHSS is asymptomatic?
Asymptomatic IHSS improves prospects but doesn’t guarantee approval. Even asymptomatic cases face significant challenges due to the risk of sudden death. Completely asymptomatic with minimal hypertrophy, no obstruction, no arrhythmias, and no family history represents the only scenario with any traditional coverage possibility—and even then, expect high table ratings and many declines.
What happens if my IHSS worsens after I get life insurance?
Once issued, your life insurance remains in force with premiums unchanged, regardless of disease progression, provided you answered all application questions truthfully. Coverage cannot be cancelled or repriced due to worsening symptoms, increasing obstruction, arrhythmia development, or even ICD implantation after policy issue. This makes securing coverage while the disease is stable extremely valuable.
Should I try traditional life insurance first or go straight to guaranteed issue with IHSS?
For most IHSS cases, securing guaranteed issue coverage immediately makes sense rather than wasting time on likely-declined traditional applications. Consider traditional options only if you have genuinely mild disease: minimal hypertrophy (under 16mm), no obstruction (gradient under 30), asymptomatic, no arrhythmias, and no concerning family history. Even then, consult with a specialized broker who can pre-screen your case. For moderate-to-severe IHSS, skip traditional applications and maximize guaranteed issue plus group coverage immediately.
Can I appeal if I’m declined for life insurance with IHSS?
Appeals are rarely successful for IHSS since carriers decline based on the diagnosis itself due to the sudden death risk. Rather than appealing a decline, work with specialized brokers to identify alternative carriers or shift focus to guaranteed issue and group coverage. Multiple declined applications worsen your record without improving outcomes.

Requesting potential insurance for someone with HCM. Diagnosed as a child prior to “30”
Shaina,
We’d be happy to try and help, just give us a call.
Thanks,
InsuranceBrokersUSA
I was diagnosed with HCM when I was 14. Now (with a lot of luck and improved medical science) I’m 50. I remember one of the first general conversations my parents and I had with the cardiologist was about life insurance. The Doctor said in no uncertain terms that I would NEVER get life insurance. He was right on the money with that. I think that instead of giving these people false hope that they might actually have a chance to get insurance, you should be giving them alternatives so they can prepare while they still can.
Dear Dominic,
Thank you for your comment. We greatly appreciate receiving feedback from individuals who have been diagnosed with the condition we are discussing in our articles. Your input is invaluable to us.
Regarding the concerns you raised about our article, we would like to provide a detailed response:
1. In our article, we clearly state that “If you were originally diagnosed before age 40 or you are suffering from symptoms, chances are you will not be able to qualify for coverage, and you will need to seek out some kind of ‘alternative’ product like a guaranteed issue life insurance policy or an accidental death policy.” We use this language to emphasize that it is highly unlikely to qualify for traditional coverage if you have been diagnosed prior to age 40 or are experiencing symptoms. However, we acknowledge that there are numerous insurance companies in the United States, each with its own unique underwriting guidelines. Technically, it is possible that there may be a carrier with more lenient guidelines that we are not aware of.
2. Additionally, we believe it is important and accurate to state that if you were diagnosed with HCM over the age of 40 and do not experience any symptoms related to the condition, you may be able to qualify for a traditional policy at a substandard rate. This information is based on the AIG Underwriting Guidelines, which can be accessed online at http://www.cassaniinsurance.com/wp-content/uploads/2018/02/AIG-Underwriting-Guidelines.pdf, as well as other reliable sources.
We appreciate your feedback and apologize for any confusion or lack of clarity in our article. It is our goal to provide accurate and informative content to our readers. Your input helps us in our continuous efforts to improve the quality of our articles.
