In December 2025, a mother wrote to UCLA Health's Ask the Doctors column about her 31-year-old daughter suffering from leg cramps, fatigue, and brain fog. When her daughter’s apartment tested positive for mold, she was diagnosed with CIRS and prescribed a treatment called the Shoemaker protocol. The mother wanted to know if any of it was medically recognized.

The two UCLA internists who answered said that CIRS wasn’t widely seen as an established medical diagnosis, and they called the protocol "as disputed as the syndrome it is meant to treat.”

Eight months later, a different mother wrote in. Her son had been diagnosed with CIRS and had consulted multiple specialists. She didn't ask whether his illness was real. She asked who should treat it.

This time, nobody questioned the diagnosis.

If you've spent years being told your symptoms were stress, anxiety, or nothing at all, that change is worth noticing. It's also worth reading closely. What the column recommended, and what it left out, shows where CIRS and mainstream medicine actually stand right now.

Is CIRS Recognized by Mainstream Medicine Yet?

Not formally, but awareness is building. 

A big hurdle is insurance companies. 

For example, Keystone First still describes chronic inflammatory response syndrome as an investigational, not clinically proven diagnosis. Because of this, many patients run into a wall when they try to get their labs covered. 

The policy even lists the billing codes it applies to: C4a, MMP-9, TGF-β1, VEGF, MSH, VIP, ADH, and HLA-DR typing. That's essentially the core of a CIRS workup.

What's new is how the insurer defends that position. In 2026, it updated its reasoning to cite a 2023 German mold guideline, a 2025 position statement from the American College of Medical Toxicology, and an independent biomarker study, among other sources.

• The toxicology group's statement says that while mold allergies are a real concern, the evidence doesn't support inhaled mycotoxins as a cause of chronic or systemic illness indoors.

• The German guideline was developed by twelve medical societies. It recommends against several tests used to evaluate mold-related illness, including visual contrast sensitivity testing.

• The American Academy of Allergy, Asthma, and Immunology has said the evidence is insufficient to connect mycotoxin inhalation to the symptoms reported as CIRS.

It's worth being clear about what that resistance actually rests on. The CIRS model has never been only about mycotoxins. It points to the whole mix of contaminants in water-damaged buildings, including bacteria, endotoxins, and fungal fragments. The policy's central objection isn't that patients aren't sick. It's that the supporting research comes mostly from a small network of affiliated practitioners and hasn't been independently replicated.

For anyone who has been through the protocol, that can feel like a technicality. But it names exactly what would move the needle: independent researchers testing the same markers and the same process. That's why academic attention matters, even when it's cautious.

So when UCLA's column recommended practitioners instead of questioning the diagnosis, that got our attention

Where CIRS Education Is Making Strides 

In spite of the critics, the CIRS movement is energized to educate the medical community about the complexities of this condition. 

Drs. Heyman and Shoemaker created a six-week online course for health professionals seeking proficiency in treating biotoxin illness, offered through George Washington University's School of Medicine and Health Sciences, which is accredited to provide continuing medical education for physicians.

That's not a small detail. Doctors can earn accredited continuing education credit, the kind they need to maintain their licenses, from a major medical school for learning how to diagnose and treat CIRS. 

The research is building too. A 2024 review in Annals of Medicine and Surgery searched the published literature for CIRS treatments. Thirteen articles referenced treatment for CIRS. The only treatment with documented clinical efficacy was the Shoemaker Protocol, described in 11 of the 13.

How to Bring the Shoemaker Protocol to a New Doctor

An academic referral can help, especially for coordinating care, getting labs covered by insurance, or managing other conditions alongside CIRS. What matters is walking in with the process instead of hoping the doctor already knows it.

Bring your exposure history, your ERMI or HERTSMI-2 results, and any CIRS labs you've already had. Ask directly whether they know the Shoemaker Protocol and whether they'd be willing to co-manage your care with a certified practitioner. Survivingmold.com lists Shoemaker Certified Practitioners by area. 

A doctor who's curious is a good sign. A doctor who wants to start over and set aside the labs and history you've already built may be sending you back to the beginning of a loop you know too well.

The First Step of CIRS Treatment Happens at Home

Whoever treats you, the Shoemaker Protocol's first step happens outside the clinic. 

Reducing ongoing biotoxin exposure comes before binders, before VIP, before anything else. That means finding and fixing the moisture source, ideally with an indoor environmental professional. 

Air purification supports that work. For more on why this step carries so much weight, see the importance of clean indoor air for CIRS patients.

This is where the iAdaptAir comes in. Of the unit, Dr. Shoemaker has said it is "the first and last word in restoration and then maintenance of indoor air health."

Each layer handles a different problem:

• True HEPA captures mold spores and fragments down to 0.05 microns.

• Activated carbon handles MVOCs and odors.

• Ozone-free bipolar ionization releases charged ions that help inactivate airborne microorganisms and clump the smallest fragments together so HEPA can capture them.

• UV-C light and a silver antimicrobial filter keep the unit clean and prevent mold recirculation.  

It’s encouraging to see UCLA’s tonal shift toward CIRS, but there is certainly more work to be done in patient and practitioner education and adoption. 

If you’re struggling with CIRS or CIRS symptoms, clean air can be a great support. Size the right unit for your space.
