Massachusetts Healthcare Compliance.

Massachusetts is the state most often cited as having gone furthest on prescriptive cybersecurity rules. 201 CMR 17.00 obliges any organization holding personal information of MA residents — including providers — to maintain a Written Information Security Program (WISP) with named encryption, access-control, and vendor-management controls. The breach statute layers on AG/OCABR notice and mandatory credit monitoring. For a MA practice, the SRA workflow needs to produce a WISP, not just a HIPAA risk analysis.

At a glance

Breach notice window

60days

Massachusetts requires notice as soon as practicable and without unreasonable delay. Practices typically align to HIPAA's 60-day clock. AG and Office of Consumer Affairs and Business Regulation (OCABR) notice required. 201 CMR 17.00 imposes a standing duty to maintain a Written Information Security Program (WISP) with specific encryption and access-control controls.

How Massachusetts goes further than HIPAA.

The breach window in Massachusetts aligns with HIPAA’s 60-day individual-notice deadline. State-law overlays here are mostly about who else gets notified, what the personal- information definition covers, and whether any named statute (CMIA, BIPA, MHMDA, HB 300, 201 CMR 17.00, SHIELD) adds substantive duties. Notice flows through Massachusetts Attorney General + Office of Consumer Affairs & Business Regulation in addition to HHS/OCR federally.

Massachusetts's overlay layers on top of HIPAA's federal floor. The free SRA readiness check walks a small practice through discovery, threat model, controls, and gap analysis, then assembles the review-ready binder — policies, training logs, BAAs, and a breach playbook tuned to the 60-day clock and the Massachusetts Attorney General + Office of Consumer Affairs & Business Regulation notification path.
