Medical coder — skills, knowledge and links
Where this job sits in the official classifications, what those classifications say it demands, and what it connects to. Every block names its source: our own judgements, the U.S. Department of Labor's O*NET, or the U.S. Department of Education.
How it connects#
O*NET also lists (no page here yet): Medical Transcriptionists · Health Information Technologists and Medical Registrars · Medical Secretaries and Administrative Assistants · File Clerks · Patient Representatives · Document Management Specialists · Health Informatics Specialists · Statistical Assistants

no match
Singapore's SSOC 2024 has no separate occupation for clinical coders: in the Department of Statistics' correspondence table, ISCO-08 3252 (medical records and health information technicians) corresponds only partly to 42243, medical or dental receptionist, which would misdescribe this work.

Each task in O*NET's terms#
O*NET describes work as detailed activities. Each of this page's 6 tasks is matched only against the activities O*NET lists for this occupation, with a stated fit; 6 match at least one. The alignment and its fit are this site's judgement, made task by task by its AI agent (Claude) on 2026-09-26; O*NET does not align tasks like ours. The activity names are O*NET's, the translations ours.

Our task judgements#
O*NET says what this job demands. It does not say what automation is doing to it — that is what this site's 6 task judgements are for: 0 backed by a verified event, 6 platform inference. VOLO judgement
Sources and rules#
- Each block says where it comes from: this site's own judgements, O*NET, the U.S. Department of Education's CIP–SOC crosswalk, the European ESCO classification and its official crosswalk to O*NET, the ILO's ISCO-08, Singapore's SSOC 2024, or something computed mechanically from those. Nothing on this page is a rating we made up.
- O*NET's importance ratings are used only to order and shorten the lists. They are never combined with this site's impact index or evidence counts.
- The fit between our page and an O*NET occupation is our judgement and is stated per code: same job, broader, part of it, or only the closest there is.
- The ESCO and ISCO-08 fits are derived mechanically from the official ESCO–O*NET crosswalk; where we override it, we say why in our data (for example, the crosswalk pairs radiologists with radiographers, which is a different job). The SSOC 2024 fit is our reading of the Singapore Department of Statistics' own titles and definitions. Official names are shown as their publishers write them; we do not translate them.
- Each task is matched only against the detailed work activities O*NET lists for the codes this page maps to. Where nothing fits, the page says why instead of forcing a match: work O*NET does not describe yet (used only for tasks we judge to be emerging), or nothing in O*NET's list for this occupation. An alignment never changes a task's direction, its basis or the impact index.
- Rules are read only from this site's verified records. A rule's official name must appear word for word in a record that reads it, so no name is made up; a policy mandate is read only as 'must', 'must not' or 'funds', because 'should' and 'in principle' are not a mandate. Reading a rule never changes a task's direction, its basis or the impact index.
