The Digital Agency announced on October 14, 2026 that it has updated the list of hospitals and pharmacies that have introduced online eligibility confirmation for medical expense subsidies, as well as the system usage terms for medical institutions, under its Public Medical Hub (PMH) initiative ^[1]. PMH is an information-sharing system developed by the Digital Agency, working with relevant ministries, to digitize procedures in areas such as medical expense subsidies, vaccinations, and maternal and child health using My Number cards ^[1].

According to the Digital Agency, PMH allows people to use their My Number card as their medical expense subsidy recipient certificate or clinic card when visiting hospitals and pharmacies, reducing the need for paper-based procedures ^[1]. In the vaccination and maternal-child health fields, the system also allows pre-visit questionnaires to be filled in online and My Number cards to be used as vaccination or checkup vouchers, with vaccination and checkup histories viewable in real time on the Mynaportal portal ^[1].

The number of participating municipalities has grown from 183 at the end of fiscal 2024 to 611 as of October 1, 2026, out of a total of 622 municipalities nationwide, and the Digital Agency expects all municipalities to eventually join ^[1]. The number of hospitals and pharmacies able to use PMH has also expanded, from about 25,000 in April 2025 to about 69,000 by March 2026 ^[1].

The Digital Agency has published an updated Excel list, dated October 14, 2026, of hospitals and pharmacies that have introduced online eligibility confirmation for medical expense subsidies, as well as a separate list, dated October 1, 2026, of participating municipalities ^[1]. It also updated technical materials for municipalities and system vendors, including master layout specifications and an error code list, and revised the PMH system usage terms for medical institutions ^[1].

The Digital Agency advises checking the official lists directly, and notes that details on which municipalities are currently participating or planning to participate can also be confirmed via the Ministry of Health, Labour and Welfare's website ^[1]. Actual availability varies by institution and municipality, and the Digital Agency recommends contacting local authorities to confirm operational status ^[1].
