I87.0 — Postthrombotic syndrome
I87.0 is a non-billable header ICD-10-CM code for postthrombotic syndrome. 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.
- chronic venous hypertension without deep vein thrombosis (I87.3-)
Inclusion terms
Alternative wordings a physician may use in the chart for this same code.
- Chronic venous hypertension due to deep vein thrombosis
- Postphlebitic syndrome
Other codes that can never be billed with I87.0
These codes carry an Excludes1 note pointing at I87.0. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading I87.0 alone.
- I87.3Chronic venous hypertension (idiopathic)
Risk adjustment
I87.0 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 I87.0
5 child codes. Green means billable.
