To meet federal requirements, large health plans must obtain a national health plan identifier number (HPID) by November 5, 2014. For this requirement, a large health plan is one with more than $5 million in annual receipts. The Department of Health and Human Services (HHS) has said that since health plans don’t have receipts, insured plans should look at premiums for the prior plan year and self-funded plans should look at claims paid for the prior plan year.
