Can someone please help! We are trying to assign the correct ICD 9 code for a subtherapeutic anticoagulation level? We seem to be getting this dx frequently. Thanks in advance!!!
 
You should check with the MD if he/she meant an adverse effect of an anticoagulation therapy. If so, code first the symptoms and then code E934.2. If it was a poisoning, follow poisoning coding guidelines.
 
Subtherapeutic is too little...not too much

790.92 is absolutely correct.

To use 964.2 and E934.2, you are essentially telling the insurance company that this patient received WAY TOO MUCH and sub-therapeutic means they received not enough...that the level is below therapeutic.

Cheers!
