I82.4Y — Acute embolism and thrombosis of unspecified deep veins of proximal lower extremity
I82.4Y is a non-billable header ICD-10-CM code for acute embolism and thrombosis of unspecified deep veins of proximal lower extremity. It cannot be billed on its own: choose one of the more specific child codes below.
Inclusion terms
Alternative wordings a physician may use in the chart for this same code.
- Acute embolism and thrombosis of deep vein of thigh NOS
- Acute embolism and thrombosis of deep vein of upper leg NOS
Other codes that can never be billed with I82.4Y
These codes carry an Excludes1 note pointing at I82.4Y. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading I82.4Y alone.
- I82.40Acute embolism and thrombosis of unspecified deep veins of lower extremity
Risk adjustment
I82.4Y 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.
How I82.4Y is indexed
Coders do not find codes by browsing the tabular list — they look them up in the alphabetic index, under the word the physician wrote. These are the index entries that lead here, so you can see which chart wordings map to I82.4Y.
