Search across every system at once, open a rich detail page for any code, and convert codes between systems instantly. No account, no clutter. WHAT YOU CAN DO • Search all four terminologies at once, or filter to one • Read a clear, structured detail page for any code — definition, attributes, hierarchy, notes, and synonyms • Cross-reference codes: jump between SNOMED CT and ICD-10-CM, or RxNorm and SNOMED CT • Convert a code from one system to another with the crosswalk tool • Browse the full hierarchy of each terminology, natively • Look up drugs by NDC — paste an NDC and get the match instantly • Save favorites and revisit recently viewed codes • Look up a selected code straight from the Share sheet in any app • Light and dark themes; built for both iPhone and iPad DESIGNED FOR Clinicians, nurses, medical coders and billers, health-IT and informatics teams, and students who need a quick, reliable code reference.
