FAQS ABOUT AFFORDABLE CARE ACT 
IMPLEMENTATION PART 46 
June 4, 2021 
Set out below are additional Frequently Asked Questions (FAQs) regarding implementation of 
the Affordable Care Act.  These FAQs have been prepared jointly by the Departments of Labor, 
Health and Human Services (HHS), and the Treasury (collectively, the Departments).  Like 
previously issued FAQs (available at http://www.dol.gov/ebsa/healthreform/ and 
https://www.cms.gov/cciio/resources/fact-sheets-and-faqs#Affordable_Care_Act), these FAQs 
answer questions from stakeholders to help people understand the law and promote compliance. 
Limitations on Cost Sharing under the Affordable Care Act 
Public Health Service Act (PHS Act) section 2707(b), as added by the Affordable Care Act, 
provides that all non-grandfathered group health plans, including non-grandfathered self-insured 
and insured small and large group market health plans, shall ensure that any annual cost sharing 
imposed under the plan does not exceed the limitations provided for under section 1302(c)(1) of 
the Affordable Care Act.1 Under section 1302(c)(1), an enrollees cost sharing for a plan year 
0F
for essential health benefits is limited. This annual limitation also applies to non-grandfathered 
health insurance coverage offered in the individual and small group market through the essential 
health benefits requirements of PHS Act section 2707(a). 
For plan or policy years beginning in 2014, the maximum annual limitation on an individual's 
cost sharing under Affordable Care Act section 1302(c)(1) (sometimes called the maximum out-
of-pocket limit or MOOP limit) was set by reference to section 223(c)(2)(A)(ii) of the Internal 
Revenue Code. For plan or policy years thereafter, the maximum out-of-pocket limit is increased 
by the premium adjustment percentage described under Affordable Care Act section 1302(c)(4). 
For plan or policy years beginning in 2021, the maximum annual limitation on cost sharing is 
$8,550 for self-only coverage and $17,100 for other than self-only coverage.  
In the proposed HHS Notice of Benefit and Payment Parameters (NBPP) for 20222 (Proposed 
2022 NBPP), HHS proposed new values for, among other things, the premium adjustment 
percentage and maximum annual limitation on cost sharing for the 2022 plan year. The proposed 
2022 plan year maximum annual limitation on cost sharing, if finalized, would have been $9,100 
for self-only coverage and $18,200 for other than self-only coverage.3 However, HHS did not 
finalize these values as proposed, and instead finalized a change in the calculation of the 
premium adjustment percentage and cost-sharing parameters that ultimately lowered the final 
values for the maximum annual limitation on cost sharing for self-only and other than self-only 
coverage for the 2022 plan year. The Departments are issuing these FAQs to help ensure that

maximum annual limitation on cost sharing for the 2022 plan year. 
Q1: What is the maximum out-of-pocket limit for plan years beginning on or after January 
1, 2022? 
The maximum annual limitation on cost sharing for the 2022 plan year will be $8,700 for self-
only coverage, and $17,400 for other than self-only coverage.4 
Q2: Why did HHS finalize different maximum out-of-pocket limits for the 2022 plan year 
from the ones that were proposed? 
In response to the Proposed 2022 NBPP, HHS received public comments objecting to the 
method used to calculate the proposed premium adjustment percentage. This methodology, set 
forth in the 2020 NBPP,5 utilizes National Health Expenditure Accounts (NHEA) estimates of 
private health insurance premiums for the private health insurance market (excluding Medigap 
and the medical portion of property and casualty insurance) as a measure of premium growth. 
Commenters expressed concern, among other things, that the use of a measure that includes 
individual market premiums has led to more rapid increases in consumer costs than would have 
occurred had HHS retained the method used to calculate the premium adjustment percentage 
prior to the 2020 plan year.  Commenters requested that HHS readopt the pre-2020 methodology, 
which used NHEA estimates of employer-sponsored insurance (ESI) premiums as a measure of 
premium growth.  HHS agreed with commenters and in the HHS Notice of Benefit and Payment 
Parameters for 2022 and Pharmacy Benefit Manager Standards final rule,6 HHS finalized a re-
adoption of the NHEA ESI premium measure to calculate the premium adjustment percentage 
and other cost-sharing parameters, including the maximum annual limitation on cost sharing, for 
the 2022 plan year and beyond. The finalization of the ESI-based calculation resulted in the 
maximum annual limitation on cost sharing set forth in Q&A 1 for the 2022 plan year.
