Harris County, 2027 at a glance

Houston is home to the Texas Medical Center, and many Harris County residents count on being able to see a specialist there or at a hospital close to home. That makes your plan's network one of the most important things to check this fall, alongside your budget and your storm plan.
What the 2027 numbers show
According to CMS's 2027 plan data, Harris County residents can choose from 49 Medicare Advantage plans offered by 10 insurance companies. Of those, 41 include Part D drug coverage, and 41 charge no monthly plan premium.
The out-of-pocket maximum is the most you'd pay in a year for covered, in-network care. In Harris County it ranges from $1,500 to $9,850. If you have a hospital stay or a run of specialist visits, that cap can matter more than the monthly premium.
Prefer to keep Original Medicare? There are 10 stand-alone Part D drug plans available, with premiums starting at $5.30 a month.
Networks and the Texas Medical Center
Harris County is spread out, and care is too. Before you choose a plan, think about where you actually go:
- Your specialists. If you see a cardiologist, oncologist, or other specialist, confirm that the specific doctor and the facility where they practice are in network for 2027. Don't assume that because one doctor in a building is covered, all of them are.
- Referrals. Medicare notes that in most HMO plans you need a referral to see a specialist. If you see several specialists, ask how referrals work before you enroll.
- Distance. A plan's network may be strong in one part of the county and thinner in another. If you live in Katy, Baytown, Kingwood, or Pasadena, check the providers closest to your home.
Hurricane season and your Medicare
Harris County sits in the path of Gulf storms, and evacuations or power outages can separate you from your usual pharmacy and doctors.
A few simple steps help:
- Keep your Medicare card, plan card, and a written list of your medications in your go-bag.
- If you evacuate and expect to be away a while, Medicare says you can ask your drug plan about a 60- or 90-day supply.
- You can print an official copy of your Medicare card from your secure account on Medicare.gov if yours is lost.
If you have Medicare and Medicaid
Harris County has 23 Dual Special Needs Plans (D-SNPs) for people who have both Medicare and Texas Medicaid. These plans are designed to help coordinate the two programs. There are also 20 plans for people with certain chronic conditions and 7 plans for people who live in a nursing home or similar facility.
