This page names those offices and claims nothing from any of them
Two sentences about the same office can look alike and be opposites. Naming a benefit your family may be entitled to, and naming the body that pays it, is a statement about your rights: those offices exist, and what they owe a surviving family has nothing whatever to do with which funeral home you rang. Saying that a funeral home is approved, accredited, contracted, endorsed or on somebody's list would be a statement about the funeral home instead, and it is a completely different kind of claim.
This page does the first and never the second. Nothing here is a credential. No office or insurer named above has approved, appointed or endorsed this business, none of them has been asked to, and helping a family claim what it is owed needs no permission from any of them. If a funeral home ever tells you it is the approved one, or the one that a particular office deals with, ask what the approval is, who granted it, and where you can read it. The answer is usually that the word was doing work no fact behind it was doing.
