Need help finding gastroenterologist (and vision/dermatology) that take Medicaid in Houston

Ive been trying to find a gastroenterologist that takes Medicaid in the Houston area, but I’ve had no luck. I already used the Find My Provider tool, but most of the listings are outdated and lot of the numbers don’t work or the offices no longer accept Medicaid.

If anyone has a recent referral or personal experience with a GI doctor who actually takes Medicaid, I’d really appreciate it.

I’m also looking for recommendations for vision and dermatology providers that accept Medicaid too.

Thanks in advanc I’ve been hitting dead ends everywhere
