I82.40

I82.40 — Acute embolism and thrombosis of unspecified deep veins of lower extremity

Non-billable headerICD-10-CM

I82.40 is a non-billable header ICD-10-CM code for acute embolism and thrombosis of unspecified deep veins of lower extremity. 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.

acute embolism and thrombosis of unspecified deep veins of proximal lower extremity (I82.4Y-)

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

Deep vein thrombosis NOS
DVT NOS

Excludes2 inherited from the categories above I82.40

Also inherited, and the opposite of Excludes1: these conditions are not part of I82.40, but a patient can have both, so you may code both.

Risk adjustment

I82.40 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.

I82.40 has not changed since FY2024 — no addition, revision or deletion across the three most recent ICD-10-CM releases.
