Offline ICD-10 and ICD-11 lookup for iPhone and iPad. Search by code or medical term; libraries stay on device so it works without a connection. English included, plus 14 downloadable languages. ICD-11 MMS 2026-01. ICD-10: WHO 2019 EN, WHO 2008 FR, Russian RU-346, Ukrainian NK 025:2021. Not US ICD-10-CM/PCS and not a billing workflow. No account, ads, or tracking. Free. Built by Roman at hehe.software.
I kept losing time looking up ICD codes on sites that assume you are online and patient. ICD Atlas is the pocket reference I wanted: search by code or term, download the language you actually use, and it still works when hospital Wi-Fi does not. Honest about editions — international ICD-10 and ICD-11 MMS, not US billing codes.
