Opening Message

In this month’s DataMatters, we’re sharing an inside look at how CHIA data supports two critical Commonwealth missions: lowering health care costs and reducing administrative burden in regulation. In News You Can Use, you’ll learn more about recent analysis by the Massachusetts Health Policy Commission of CHIA’s Total Medical Expenses (TME) data, which is used as part of the state’s annual cost growth benchmarking process.

Our Data User Profile feature hands the pen to the Division of Insurance (DOI) for a description of how CHIA APCD data has helped free DOI and its regulated payers from participating in a quarterly data submission process payer-by-payer. As a one-stop data and technical assistance shop, CHIA is helping increase the Division’s speed and efficiency in achieving its mission to ensure the financial solvency of the companies it regulates.

Don’t forget to scroll to the end, where you’ll get to review the recent CHIA publications and data releases you might have missed, and a list of upcoming events that may pique your interest.

DataMatters is a newsletter for you, the stakeholders interested in the data we collect, release, and report on. We hope you will enjoy reading and learn something new, and we always want to know what you think. Please share your ideas and questions by emailing

Our warmest wishes for a happy, and safe, holiday season. See you in 2022.

News You Can Use 

Each year, as part of the Commonwealth’s health care cost growth benchmarking process, CHIA monitors the amount paid to providers for health care services delivered to a payer’s member population using a metric known as Total Medical Expense (TME). TME is also examined on a Health Status Adjusted (HSA) basis for each payer to reflect differences in member populations. CHIA reports on HSA TME in the agency’s Annual Report.

Recent analysis of unadjusted TME and HSA TME data by the Massachusetts Health Policy Commission (HPC) found meaningful differences trending the two metrics. Over a six-year period, HSA TME grew steadily at 7.6% (Figure 1). Disaggregating the components of HSA TME, the HPC found risk scores grew 15.0% at the same time. The rate of unadjusted growth in TME over this period was 22.6%. These differences have tangible implications for health policy decisions in Massachusetts.

CHIA is statutorily responsible for confidentially referring a list of payers and primary care providers whose increase in HSA TME jeopardizes the state’s ability to meet the health care cost growth benchmark to the HPC every year. In an effort to understand how those referrals may be impacted by this trend, the HPC also compared unadjusted and HSA TME for three large provider groups and the three major payers. Among the sample of 71 payer-provider contracts that were examined, unadjusted TME growth exceeded the benchmark for 47 (66%), but only 17 (24%) had HSA TME growth that exceeded the benchmark, triggering referral (Figure 2).

These findings have led the HPC to recommend that the Legislature allow CHIA to use additional metrics besides HSA TME to determine whether a provider or payer should be identified as contributing to excessive health care spending.

CHIA will continue to report on spending trends in its Annual Report. Tune in late winter ’22.

Data User Profile

Each edition of DataMatters features an interview with a CHIA data user, focusing on their experience obtaining and using our data and how it is used. We are grateful to Kevin Beagan, Deputy Commissioner at the Massachusetts Division of Insurance (DOI), for his interest in discussing the DOI’s ongoing use of CHIA APCD data as the basis for its quarterly HMO Membership Reports (and in the future, adding Utilization Reports).


DataMatters Nov 2021 Data User Profile NOV21


These second quarter HMO Membership Reports, produced by the Massachusetts Division of Insurance using CHIA’s APCD data and technical assistance, shows shifting payer market shares in fully-insured HMO products over the past few years (shown above: 2020 and 2021). 


Which CHIA data did you use?

Member Eligibility and Product files from a select group of payers. The process runs directly against CHIA’s APCD Data Warehouse to produce the reports.


Why APCD data?

The Division of Insurance relies upon regular membership and utilization reports from licensed health carriers [focusing on HMO carriers] to track changes in individual company operations and overall market trends. While we [previously] collected this information from carriers, in order to promote administrative simplification, we have worked with carriers and CHIA to develop summary reports from the APCD so that companies do not need to submit information to the Division.


Why is the reporting limited to HMOs?

Insurance companies usually offer a number of products. For example, United Healthcare can offer dental, vision or disability income products under its license. HMOs are restricted to offering comprehensive health products and we track their business in particular because coverage can be volatile with changes in the market, and this could markedly impact the financial health of any one HMO company. Only fully-insured (aka not self-insured) HMO business is tracked. Note: DOI’s primary mission is to monitor the solvency of its licensees in order to promote a healthy, responsive and willing marketplace for consumers who purchase insurance products.

Please describe your experience using CHIA data?

CHIA staff have been extremely supportive throughout our process to assist with creation of appropriate computer coding needed to aggregate and develop reports. They have also helped to develop a process for carriers to validate the reasonableness of the information generated from the APCD. While we have been able to establish a regular process for APCD-generated membership reports, utilization is trickier and we are still going through a vetting process with carriers to make sure that the codes being used to group data are properly reporting carrier utilization. We hope to be producing regular utilization reports starting in 2022.


Which type of APCD data (e.g., data fields or calculations) is critical to your reporting?

Membership, as well as inpatient, outpatient, and pharmacy claims data.

What takeaway information would you like to highlight from your experience using our data?

It is necessary to have a feedback loop with carriers to validate that the reported information is consistent with their own experience. It is important to do careful work upfront to make sure that computer logic will pick up any unique characteristics of a company’s APCD data and that companies are able to see the APCD-reports so that they can validate that the information is correct and/or suggest changes that may need to be made to their APCD data.


Publications and Data Releases

Mandated Benefit Review

CHIA released its review of An Act relative to mental health providers (H1114/S1262) to the legislature and online last week. CHIA is statutorily required to produce these reviews, which assess proposed new insurance mandates for potential efficacy and likely impact of the mandate on health costs (via fully-insured health plans). The bills in question would require occupational therapists (OTs) and occupational therapist assistants (OTAs) to be statutorily recognized as mental health providers and therefore require health plans to reimburse for their provision of mental health services.


Massachusetts Acute Care Hospital Inpatient Discharge Data (FFY 2016-2019), quarterly update

The latest quarterly update to the Massachusetts Acute Care Hospital Inpatient Discharge Data (FFY 2016-2019) report was released last month. It includes data from October 2018 – June 2021. Using interim data, the update offers insights into patterns and trends on key inpatient utilization measures through a series of interactive dashboards; also included are the report overview, technical appendix, and Excel databook.


Case Mix Outpatient Observation Database, FY2020
CHIA’s Case Mix (Hospital Discharge) Outpatient Observation Database for FY2020 was released in October and is now available to external applicants. 


Cost Report Filing Instruction Webinars
By state regulation, CHIA requires providers of adult foster care and group adult foster care to submit cost reports for each fiscal year. The reports track costs incurred in the provision of this care and are used by CHIA and other public entities for monitoring costs and for payment policy development. In August and October this year, CHIA’s Pricing Team staff conducted two 30-minute live webinars to help providers complete their reports. These webinars are posted here and here.
