I80.8 — Phlebitis and thrombophlebitis of other sites
I80.8 is a billable, specific ICD-10-CM code for phlebitis and thrombophlebitis of other sites. It is valid for submission on a claim.
Other codes that can never be billed with I80.8
These codes carry an Excludes1 note pointing at I80.8. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading I80.8 alone.
- N61Inflammatory disorders of breast
Risk adjustment
I80.8 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.
Medicare coverage
I80.8 is named in 11 Medicare coverage policies — 11 listing it as supporting medical necessity. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.
