Affiliate Filings

Connecticut hospitals and hospital systems must submit to the Office of the Attorney General (“OAG”) and to the Office of Health Strategy (“OHS”), a written report describing each affiliation with another hospital or hospital system.
What is the statutory authority for this filing requirement?
Connecticut General Statutes (C.G.S.) §19a-486i(i) as amended by Section 56(i) of Public Act 18-91.
When is this filing due?
The Annual Reports must be filed with OAG and OHS no later than January 15th, and annually thereafter.
What is an affiliation for purposes of this filing?
“Affiliation" means the formation of a relationship between two or more entities that would permit the entities to negotiate jointly with third parties over rates for professional medical services.
Who needs to submit this new filing requirement?
  • Connecticut hospitals as defined in Connecticut General Statutes (C.G.S.) §19a-490, which includes all general, children's, chronic disease, psychiatric, hospital and maternity hospital facilities.
  • Hospital Systems as defined in Connecticut General Statutes (C.G.S.) §19a-486i(a)(4).
    Note that the higher level system parent of a hospital system should be the reporting entity. However, the contact person should be an in-state representative of the system. Further note that the only business entities and hospitals required to report are those operating in Connecticut.
