Questions About I80.8Overview
What is the ICD-10 code for phlebitis and thrombophlebitis of other sites?
The ICD-10-CM code for phlebitis and thrombophlebitis of other sites is I80.8 (sometimes written as I808). It is billable on HIPAA-covered claims from October 1, 2026 through September 30, 2027.
Is I80.8 (Phlebitis and thrombophlebitis) a billable code?
Yes. This is a billable ICD-10-CM code, specific enough to report phlebitis and thrombophlebitis of other sites on HIPAA-covered claims from October 1, 2026 through September 30, 2027.
What MS-DRG does I80.8 group to?
When phlebitis and thrombophlebitis of other sites is the principal diagnosis on an inpatient stay, it groups to MS-DRG 301, 300, 299, with relative weights from 0.7132 to 1.5840 depending on complications. Higher weights mean higher Medicare reimbursement.
Can I80.8 be reported with a code from I82.4?
Not as a rule. The Excludes1 note at I80, which applies to I80.8, lists "venous embolism and thrombosis of lower extremities (I82.4-, I82.5-, I82.81-)". An Excludes1 note means the excluded code is never reported together with this one; the only exception is when the two conditions are unrelated to each other (Official Guidelines, Section I.A.12.a).
What is coded first with I80.8?
The Code First note at I80, which applies to I80.8, reads: if applicable: phlebitis and thrombophlebitis complicating abortion, ectopic or molar pregnancy (O00-O07, O08.7); phlebitis and thrombophlebitis complicating pregnancy, childbirth and the puerperium (O22.-, O87.-). When one of these applies, it is sequenced before I80.8.
