FMCSA Renews Diabetes Assessment Form MCSA-5872: What CDL Drivers Need to Know

FMCSA Is Renewing Its Diabetes Assessment Form — Here's What That Means for You

I've been examining commercial drivers for over 40 years, and one of the most common health conversations I have in my exam room is about diabetes. So when FMCSA published a notice on August 25, 2026 to renew the MCSA-5872 — the Non-Insulin-Treated Diabetes Mellitus Assessment Form — I want to make sure you understand what this form is, why it exists, and what it means if you're managing diabetes and holding a CDL.

This isn't a dramatic rule change. It's a renewal — FMCSA is going through the required federal paperwork process to keep this form officially approved for continued use. But the notice is a good reminder that this form matters, and too many drivers don't know it exists.

What Is the MCSA-5872?

In plain English: the MCSA-5872 is a structured tool that certified medical examiners like me can use to communicate with your treating physician or diabetes care provider before making a certification decision.

Here's the situation it's designed for. You come in for your DOT physical. You have non-insulin-treated diabetes mellitus — meaning you're managing your blood sugar through diet, oral medications, or non-insulin injectables. I need to determine whether your diabetes is controlled well enough that you can safely operate a commercial motor vehicle under FMCSA's physical qualification standards.

That's not always a decision I can make on exam findings alone. Your A1C history, your medication regimen, whether you've had hypoglycemic episodes — that context lives with your treating provider. The MCSA-5872 gives me a formal, standardized way to request that information directly.

One important point: using this form is voluntary on my end. FMCSA doesn't require me to use it in every case. But when I do reach for it, it's because I want to make the most informed decision I can on your behalf — not because I'm looking to disqualify you.

Why Does This Renewal Matter?

FMCSA has to periodically reauthorize its information collection tools under the Paperwork Reduction Act. This renewal process — which goes through the Office of Management and Budget — keeps the form legally valid for continued use. Without it, the form couldn't be used, and the line of communication between examiners and your treating providers would have one fewer formal pathway.

The fact that FMCSA is renewing it tells me they intend to keep this tool in play. That's good news for drivers with diabetes, because it supports a more complete picture of your health rather than a snap judgment.

What Should You Do If You Have Non-Insulin-Treated Diabetes?

Here's my practical advice, from someone who has sat across from thousands of drivers managing this condition:

1. Get your records together before your exam.

Bring documentation of your most recent A1C, your current medication list, and any notes from your endocrinologist or primary care physician. The more I can see, the better I can evaluate your situation.

2. Don't assume diabetes is automatically disqualifying.

Non-insulin-treated diabetes mellitus is not an automatic disqualifier under FMCSA standards. Many drivers with well-controlled diabetes are certified every year. What matters is control, stability, and the absence of complications that would impair safe driving.

3. Be honest on your health history form.

I can't help you if I don't have the full picture. Omitting a diabetes diagnosis isn't worth the risk — to your certification, your career, or the people sharing the road with you.

4. Keep your treating provider in the loop.

If I do use the MCSA-5872 to reach out to your doctor, a response from them helps me make a faster, better-informed decision. Let your provider know you drive commercially — that context shapes how they manage your care too.
