Rather than consult Healthcare.gov, it would be better to go straight to the insurance carrier and ask them if your plan is HDHP qualified. The reason is that there are some subtle differences between high deductible plans that may render some plans not suitable for an HDHP. See High Deductible Health Plan (HDHP) on page 3 at https://www.irs.gov/pub/irs-pdf/p969.pdf.
It can be difficult for the non-insurance professional to be able to discern if a plan qualifies to be an HDHP in the sense that the IRS uses it for purposes of having an HSA, but the insurance carrier ought to know.
