D68.6Other thrombophilia

Non-billable headerICD-10-CM

D68.6 is a non-billable header ICD-10-CM code for other thrombophilia. It cannot be billed on its own: choose one of the more specific child codes below.

Excludes1 — never code together

These conditions cannot occur together. Billing both on the same encounter is a denial.

  • diffuse or disseminated intravascular coagulation [DIC] (D65)
  • heparin induced thrombocytopenia (HIT) (D75.82-)
  • hyperhomocysteinemia (E72.11)

Inclusion terms

Alternative wordings a physician may use in the chart for this same code.

  • Other hypercoagulable states

Other codes that can never be billed with D68.6

These codes carry an Excludes1 note pointing at D68.6. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading D68.6 alone.

  • D68.5Primary thrombophilia

Risk adjustment

D68.6 does not map to an HCC and does not risk-adjust under CMS-HCC V28. That is normal — most ICD-10 codes do not. It still needs to be coded correctly; it just will not move a RAF score.

Code to one of these instead D68.6

3 child codes. Green means billable.
