The Ministry of Health list of ICD-10 codes used in Vietnam since 01/07/2026 (Thông tư 06/2026/TT-BYT, appendix "Danh mục mã bệnh tật, nguyên nhân tử vong theo ICD-10", 15,844 codes): code=E11.9 (also E119 or the path /v1/vn-icd10/E11.9) returns the Vietnamese name, its category, the hierarchy (22 chapters, blocks and sub-blocks with their Vietnamese names), sub-codes, the dagger (†) / asterisk (*) mark and the usage rules of columns 24–29 of the appendix: not usable as the main diagnosis, discouraged as main diagnosis, not usable because a more specific 4- or 5-character code exists, cause of death only, female-only and male-only codes.
q=dai thao duong searches the Vietnamese names without accents (all words must match, codes by prefix), optionally within a chapter. codes=E11.9,I10,A00 checks up to 1,000 codes at once, as a claims or HIS validation would: unknown codes, codes that need a more specific subdivision, codes that cannot be the main diagnosis, and with sex=male|female sex-specific codes. chapter=IV or group=E10-E14 browses the tree.
Only the Vietnamese texts published in the circular are served (no WHO English descriptions, inclusion / exclusion notes are left out). The data is rebuilt weekly from the appendix PDF when it changes. This is a coding aid, not medical advice.

FAQ
Which edition is it?
The list of Thông tư 06/2026/TT-BYT (issued 02/04/2026, in force 01/07/2026), which replaces the list of QĐ 4469/QĐ-BYT (2020). Each answer names the source.
What does "main_diagnosis_allowed: false" mean?
The circular marks the code as not usable (or a more specific code is required, or cause of death only) or as an asterisk manifestation code, so it cannot be the main diagnosis (bệnh chính).
Are English names included?
No. Only the Vietnamese names of the legal document are served; the WHO English descriptions are not redistributed.
