Here is the opinion in San Carlos Apache Tribe v. Beccera.
A simplified example clarifies this scheme. Assume that a tribe administers a $3 million healthcare program for its members. It costs the tribe $500,000 in administrative costs to do so. IHS therefore will pay the tribe $3.5 million. Additionally, the tribe recovers $1 million for those procedures from outside insurers. It is statutorily required to spend that $1 million on health care as well.
But there is a hole in this statutory scheme. Who pays the CSC for that additional $1 million in health care that the tribe must provide with its third-party revenue? At the heart of this lawsuit is Plaintiff-Appellant San Carlos Apache Tribe’s (“the Tribe”) contention that IHS must cover those additional CSC.
