What Is Inclusion Body Myositis and Why It Matters

Inclusion Body Myositis (IBM) is a rare, progressive muscle disease that causes weakness and disability. For veterans, IBM can make daily tasks and employment difficult. Until now, getting VA disability compensation for IBM has been challenging, as it is not formally recognized as a presumptive service-connected condition.

However, lawmakers are now advancing bipartisan legislation to expand benefits for veterans with IBM. If passed, this will directly affect how claims are processed and may make it easier to qualify for compensation.

How the Proposed Legislation Could Change VA Claims

The new bill, championed by Rep. Bilirakis and a bipartisan group, would require the Department of Veterans Affairs to recognize IBM as a qualifying disability for service connection. This means veterans diagnosed with IBM could file a claim using VA Form 21-526EZ for disability compensation, and the VA would be required to consider IBM as potentially service-connected, depending on your service history and medical evidence.

  • If IBM is added to the presumptive list, veterans may not need to prove a direct link between military service and their diagnosis.
  • This could shorten the claims process and reduce denials for lack of service connection under current VA claims rules (see 38 CFR § 3.309).
  • Disability ratings for IBM would be based on the severity of muscle weakness and its impact on daily life, following VA rating criteria.

What Veterans Should Do Now

If you have been diagnosed with Inclusion Body Myositis, start gathering your medical records and service documents now. Even if the law has not yet passed, you can:

  • File a claim now to establish an effective date. If the law changes, you may qualify for retroactive benefits from your filing date.
  • Use VA Form 21-526EZ to submit your claim. Include medical evidence showing your IBM diagnosis and how it affects your daily life.
  • Track the bill’s progress via the VA or your Congressional representative, and check for updates on our explainers page.

How IBM Could Be Rated by the VA

The VA rates muscle diseases under 38 CFR § 4.73, Diagnostic Codes 5301-5329. While IBM does not have a specific code yet, it is likely to be rated by analogy to other progressive muscle disorders. Ratings typically range from 10% to 100% based on the degree of muscle weakness, mobility loss, and impact on employment.

Stay Informed and Prepare for Changes

Legislation can move quickly or stall, so stay informed through reputable sources and VA updates. If you are denied for IBM now, consider filing a Notice of Disagreement (NOD) if the law changes, as you may become eligible for benefits under new rules.
