Contributing to IRA to reduce MAGI for continued Medicaid eligibility in Ohio

I recently got a new job and my income has increased significantly so I will lose my Medicaid, but my job's healthcare plans are expensive and if I have to pay for a plan it'd genuinely be better for me to quit and find another job where my income remains under the monthly limit for eligibility. The deductibles, copay, coinsurance, etc. end up being kind of ridiculous especially because I require a lot of medical care and prescriptions. I would really love to keep the job, though.

I'm in the process of getting access to MBIWD, but it's taking too long and the process is extremely confusing and hard to navigate. I have to waive or enroll in benefits by beginning of January and cannot make changes until end of calendar year next year so I need to make a decision ASAP. Marketplace plans have skyrocketed since they got rid of tax credits and would actually be worse than my work benefits.

To be clear, while I am currently trying to apply for MBIWD for long-term coverage as I begin a real career, I have not been deemed disabled by Medicaid and from what I have read online, I believe I am enrolled in Medicaid Expansion which is for adults with no dependents and has no asset limit. Please correct me if I am wrong as that changes my situation. I've never been asked about my assets, I have only had to submit paystubs occasionally to prove income. I've never received SSDI or disability benefits because I can work (while medicated and receiving the services I do). I've always been on Medicaid due to having a low income and I currently file by myself.

I am wondering if contributing to a traditional IRA, since it will lower my MAGI, will allow me to continue to be eligible for my Medicaid while I wait for MBIWD. This was suggested to me and seems to be a solution based on my research, but I am skeptical. I am open to other suggestions/advice as well. I have asked HR if I can reduce my hours, but I am doubtful that would be approved.
