Wiki MTHFR dx code needed...

I use 270.4 "disturbances of sulphur-bearing amino-acid metabolism" based on some research from a few weeks ago. It's complicated stuff! OB patients with a +mthfr may have a condition from 289.91 including antithrombin III, Factor V leiden, protein S, protein C, Prothrombin gene mutation and homocysteine 270.4.

I hope this helps! :)
 
In our office we code MTHFR using the following codes:
649.33 (primary) coagulation defects complicating pregnancy and 286.9 MTHFR.
Also, for Factor XIII the secondary code would be 286.3
Factor V, Prothrombin gene mutation, Protein C & S, Anti-3 the secondary code would be 289.81.

Hope this helps.
