Wiki djd knee dx

[psacco]

question: report states "DJD left knee"... I have been coding as M17.12, but my supervisor says that is should be M17.9 for unspecified. I disagree, on the thought that it says left knee, and if it does not state either primary or secondary, it defaults to primary.....any help would he appreciated. thank you.

It does not default to primary this must be documented as either osteoarthritis with no known cause or age related osteoarthritis , something along that line. This is why the unspecified option is available.
