NYC Dept of Health & Mental Hygiene

The New York City Department of Health and Mental Hygiene (DOHMH, branded "NYC Health") is one of the largest and oldest municipal public-health agencies in the United States, with roots going back to 1805. It serves roughly 8.3 million residents and runs an exceptionally broad mission: communicable- and chronic-disease surveillance and outbreak response, immunizations, the City's public-health laboratory, vital records (birth/death certificates), restaurant and environmental-health inspections, school health, and mental-hygiene (behavioral-health) services.

DOHMH is fundamentally data- and surveillance-intensive — its Bureau of Communicable Disease tracks 70+ reportable conditions, and it operates citywide systems for syndromic surveillance, immunization registries, electronic lab reporting, and population-health analytics.

Importantly, DOHMH does not run citywide IT on its own: like all NYC agencies it sits under the Office of Technology and Innovation (OTI) for shared infrastructure, citywide contracts, cloud review, and cybersecurity (NYC Cyber Command), while maintaining its own Division of Information Technology and informatics teams for mission-specific health systems. A January 2026 mayoral transition installed a new administration and a new Health Commissioner, so leadership and priorities are still settling.

DOHMH is a large direct spender on a citywide health mission, but it is not a central IT buyer — its technology dollars flow through OTI's citywide vehicles and its own mission-IT division rather than a standalone procurement authority. The FY2026 Executive Budget proposed roughly $2.31 billion for DOHMH, split across a Public Health division (~$1.42B) and a Mental Hygiene division (~$775M). At Commissioner Martin's January 2026 appointment, the agency was described as having more than 7,000 employees and an annual budget of about $1.6 billion (a figure that reflects City-funded operations and excludes large pass-through/grant streams).

• A large share of DOHMH funding is federal and state grants tied to specific programs (HIV, immunization, emergency preparedness); these can shift with federal public-health funding decisions and create budget volatility independent of the City line.
• Mission-specific health IT is funded inside DOHMH, but shared infrastructure, citywide contracts, and cybersecurity run through OTI — confirm which entity owns a given system before forecasting.
• The Mamdani administration adopted its first full budget — a $125.8B citywide FY2027 plan — via a June 30, 2026 handshake with the Council; it funds mental-health services DOHMH helps oversee and a $34.2M post-9/11 health-records portal. Confirm the DOHMH-specific FY2027 line as adopted budget detail publishes.

Selling into DOHMH means navigating two layers: NYC's citywide contracting machinery and OTI's role as the technology gatekeeper. DOHMH buys through its own Agency Chief Contracting Officer (ACCO) under the Mayor's Office of Contract Services (MOCS), but technology — especially cloud and shared infrastructure — flows through OTI's citywide/requirement contracts and must clear OTI's cloud-review and Cyber Command security gates.
