Wiki M Codes

[arbrown2002]

Ok, for the life of me, I cannot figure out what an M Code is. My options are neoplasms, maternal conditions, manipulations and myocardial infarctions.

Can someone help me out, please?

Thank you.

M codes are for the Morphology of neoplasms. They are used primarily in tumor registry and never on claims.
