What Is High Deductible Plan G?
High Deductible Plan G (HDG) is a Medigap plan that provides the same comprehensive coverage as standard Plan G — but only after you meet a high annual deductible of $2,870 in 2026.
In exchange for this deductible, your monthly premium drops dramatically — from $120–$220/month for standard Plan G to just $40–$70/month for HDG. The coverage above the deductible is identical to Plan G: Part A deductible, Part B coinsurance, excess charges, foreign travel, and more.
The Math: When HDG Wins
Let's compare a 65-year-old in Orlando:
Standard Plan G: $160/month = $1,920/year in premiums
High Deductible Plan G: $55/month = $660/year in premiums
Annual premium savings with HDG: $1,260
If you have a healthy year and spend less than $1,260 in out-of-pocket costs under HDG, you come out ahead. You'd need to hit $2,870 in medical costs for HDG to perform worse than Plan G.
For a truly healthy senior who rarely uses medical care, HDG can save $1,000–$1,500/year — money that compounds over 10–20 years of retirement.
When HDG Is a Poor Choice
HDG is not right for everyone. Avoid it if:
- You manage multiple chronic conditions requiring regular specialist visits, tests, or procedures. Your deductible may be met frequently.
- You dislike financial uncertainty. With HDG, you need to be comfortable paying bills until you hit $2,870. Some seniors find this stressful.
- You're on a tight fixed income. Even if HDG saves money on average, an unexpected illness that triggers the full deductible can strain a monthly budget.
- You use medications that require infusions or major outpatient procedures. These costs apply to the deductible quickly.
