Official Updates I80.252 Phlebitis and thrombophlebitis of left calf muscular vein The official ICD-10-CM addendum was posted to the Centers for Medicare I80.253 Phlebitis and thrombophlebitis of calf muscular vein, and Medicaid Services (CMS) website on June 20, 2019, identifying the bilateral changes to the ICD-10-CM code set for fiscal 2020, effective October 1, I80.259 Phlebitis and thrombophlebitis of unspecified calf 2019, to September 30, 2020. These changes were made by the agency muscular vein charged with maintaining and updating the ICD-10-CM code set, the I82.451 Acute embolism and thrombosis of right peroneal vein National Center for Health Statistics (NCHS), a section of the Centers for Disease Control and Prevention (CDC). A summary of the changes is I82.452 Acute embolism and thrombosis of left peroneal vein provided below: I82.453 Acute embolism and thrombosis of peroneal vein, bilateral 15 Codes with a Change in Validity I82.459 Acute embolism and thrombosis of unspecified peroneal Note: Validity changes are the result of codes being added to or deleted vein from the classification. Codes that change from valid to invalid allow the I82.461 Acute embolism and thrombosis of right calf muscular vein creation of a new subcategory to which new codes can be assigned that I82.462 Acute embolism and thrombosis of left calf muscular vein provide greater detail about the condition. Codes that change from I82.463 Acute embolism and thrombosis of calf muscular vein, invalid to valid are the result of subcategory codes being deleted from the bilateral classification, when the detail provided in those codes is no longer required.
