If you mean "is not in-network with the PPO" then PPO would still be primary, but it would be treated as an out of network provider visit -- generally (not always, but often on a PPO) covered to some degree, but at a much higher out of pocket cost to you than an in-network provider. If you mean "will not file to plans other than the HMO", then that office would likely not file ANY claim to insurance (as DH's plan would still be primary), and you would have to file the claim to the PPO yourself if you were hoping to get any insurance payment on it.
As a note: if you're wondering, I know people intentionally withhold insurance info to "play" with the primary vs. secondary (i.e. - bring DS to the doc that only accepts the HMO, and just not tell them that DS is also covered on DH's PPO) -- but I would personally never do that, because if either insurance company finds out, you could easily lose benefits from BOTH plans and risk having previously paid claims revoked (which leaves you responsible for the full bill). Most member agreements require you to disclose all insurance coverages (again, best to read plan documents carefully, but that's in general...)
