ICD-10 Diagnostic Codes

Look up the right ICD-10 code in seconds — the complete classification, fully offline.

ICD-10 Diagnostic Codes is the professional coding tool for doctors, paramedics, nurses and other healthcare professionals. Find the correct ICD-10 code in seconds — at the bedside, in the ambulance, or at your desk.

The app carries the complete ICD-10 classification on your device, including the official classification notes for each code. Everything works offline: no account, no sign-in, no waiting for a network connection.

TWO CLASSIFICATIONS, ONE APP • Danish SKS (Sundhedsvæsenets Klassifikationssystem), with the D-prefixed Danish codes • US ICD-10-CM (CMS/NCHS) • Switch in Settings at any time — saved codes and history are kept separately for each classification, so nothing gets mixed up

SEARCH BUILT FOR SPEED • Results update as you type • Word search in any order: "chole ac" finds "Acute cholecystitis" • Combine a code with a search word: "pap K8" finds papilla diagnoses in the biliary tract chapter • Recent lookups are one tap away on the Search tab

BROWSE THE FULL SYSTEMATICS • All 22 chapters, their groups and every code, in hierarchical order • Drill from chapter to group to code, or jump straight into the detail view

CODE DETAILS THAT ANSWER THE REAL QUESTION • Inclusion, Exclusion and Note text for each code, where available • Tap a code reference inside a note (e.g. "Z22.-") to jump straight to that code • Parent codes and subcodes listed, so you can always find the more specific code • Clear validity flags: "Valid primary diagnosis" or "Group code" in SKS, "Billable" or "Group code — not billable" in ICD-10-CM • Placement overview showing chapter, group and code in the hierarchy • Look up the matching Wikipedia article in Danish or English with one tap

SAVED CODES AND FOLDERS • Save any code with the star button • Organize saved codes into your own folders — by department, procedure, or study topic • Export or share a list of saved codes

MADE FOR DAILY CLINICAL USE • Native iPhone and iPad app, with a two-column layout on iPad • Adjustable text size for browsing and help • Full Danish and English localization • Dark Mode, Dynamic Type and VoiceOver support • Built-in help section explaining the app and the ICD-10 system itself

PRIVACY The app collects nothing and tracks nothing. There are no analytics, no ads and no user accounts. Your searches, history and saved codes never leave your device. The only optional network request is the Wikipedia lookup you start yourself.

DATA SOURCES • Danish diagnosis data: SKS, Danish Health Data Authority (Sundhedsdatastyrelsen) • US diagnosis data: ICD-10-CM FY2027 (CMS/NCHS) • Classification notes: machine-translated from the Norwegian ICD-10 (2012), Helsedirektoratet • ICD-10 © World Health Organization, 1994–2012
