About I82.4
I82.4 is the ICD-10-CM diagnosis code for acute embolism and thrombosis of deep veins of lower extremity. It belongs to category I82 (other venous embolism and thrombosis), block I80-I89 (diseases of veins, lymphatic vessels and lymph nodes, not elsewhere classified) and chapter 9 (diseases of the circulatory system). It is a header code, so it can't be reported by itself; one of its 10 subcodes must be used instead.
Within I82 (other venous embolism and thrombosis), I82.4 is specifically for acute embolism and thrombosis of deep veins of lower extremity. Related codes cover Budd-Chiari syndrome (I82.0), thrombophlebitis migrans (I82.1), embolism and thrombosis of vena cava and other thoracic veins (I82.2), embolism and thrombosis of renal vein (I82.3), chronic embolism and thrombosis of deep veins of lower extremity (I82.5), acute embolism and thrombosis of veins of upper extremity (I82.6), chronic embolism and thrombosis of veins of upper extremity (I82.7), embolism and thrombosis of other specified veins (I82.8) and 4 more.
To report this condition, pick the subcode that matches the documentation: I82.40 (extremity), I82.41 (vein), I82.42 (vein), I82.43 (vein), I82.44 (vein), I82.45 (vein), I82.46 (vein), I82.49 (extremity) and 2 more.
Code first venous embolism and thrombosis complicating: abortion, ectopic or molar pregnancy (O00-O07, O08.7) and pregnancy, childbirth and the puerperium (O22.-, O87.-).
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
