To answer the OP's question, my company used to have a two-tiered PPO plans and one HDHP (with no company HSA). Then we went to 1 PPO plan and the same HDHP last year, and for next year, we no longer have any PPO-style choice, instead we have the true HDHP (again with no company HSA, would have to fund completely myself) and what I consider an HDHP-lite with an HRA, which has slightly higher premiums, slightly lower deductibles and OOP maxes (I call it lite because it's not technically an HDHP plan and therefore doesn't qualify for an HSA, but it's still structured almost exactly the same as the actual HDHP plan). I have wanted to switch to an HDHP for the past year, but DW preferred the PPO plan, so while I am disappointed that I'm left with no real "choice", being forced onto to HDHP-lite plan may work in my benefit, as it will give DW a year to see what it's like, and then maybe she will let me take the plunge into the true HDHP plan.
DW is a federal employee, unfortunately the formulas for their healthcare dramatically reduce the employer covered portion, and since she works part time, instead of the employee paying 25% of costs, she would have to pay about 63% of costs (I guess the VA looks at it like if a full time employee gets 75% of medical insurance covered, then a half-time employee should get only half of that 75%), which makes that plan, at least for family coverage, prohibitively expensive.
