Why was I denied my E&M when I used I73.89 with E11.40?

ANSWER: When you look up ICD-10-CM code- I73.89, this is what you see:

• I73.8 Other specified peripheral vascular diseases

• Excludes1: diabetic (peripheral) angiopathy (E08-E13 with .51-.52)

  
  

  This means you must use E11.51 or E11.52 not I73.89 with E11.40
