I’m guessing “proficient” was the intended word!

Medical coding covers a huge range of disciplines.

For medical research like protein folding, you’d be best studying Machine Learning.

For medical admin systems, you’d be best studying databases, UX and the like.

I did Computer Visualisation at university. One of our assignments was taking the huge list of numbers generated by a MRI scanner and then creating a program to parse that data into a volumetric model. That kind of thing is yet again another discipline.

None of these skills are particularly medicine-specific. If you work out what it is exactly what you want to do, you’ll more easily find resources for it.

CodeAcademy has a pretty diverse selection of courses - I signed my team up to them and they’ve all found different niches to study.
