Thank you for using our forum. My name is ***** ***** I hope to assist you today. Your prior expert opted out (this sometimes happens as we are not employees of the site and sometimes have other issues that prevent us from following up).
I am sorry to learn of this situation, I have reviewed your post above, and it appears you have a situation in which you want to sue both your private insurance carrier and TriCare (which is administered through the Department of Defense). This creates a fairly complex pattern of litigation.
Your underlying claim is usually a form of "bad faith" (what we call a breach of contract claim brought by an insured against their insurance carrier when the carrier refuses to provide the benefits stated in the plan). These tend to be somewhat complex, and there are usually only a handful of specialists that handle these, although you can usually find a general civil litigation attorney that is willing to take on the case depending on the specific facts of the claim.
Your second issue is the fact that Tricare is run by the DOD. This means that you are more likely than not going to end up in Federal Court, and dealing with the US Attorney General's Office. This doesn't mean you shouldn't sue, or that you should be overly worried about the claim, but it does mean that they take this very seriously and they tend to litigate very vigorously.
There are also other issues associated with the fact that the DOD enjoys "sovereign immunity" which means that your procedure is more nuanced and time sensitive. (So you will want to contact multiple lawyers in an effort to find one (do not call one or two and hope they might take your case, call many attorneys and then see who calls back and what they say))
Unfortunately, we cannot provide you with a specific referral on this forum, but I can provide you with a couple of resources to help you find local attorneys (remember, you can "spread a wide net" and any attorney in the state can represent you).
You can find local attorneys using the State and local Bar Association directories, or private directories such as www.AVVO.com; www.FindLaw.com; or www.Martindale.com (I personally find www.AVVO.com to be the most user friendly).
