I80 — Phlebitis and thrombophlebitis
Not billable
Is I80 billable?
No — I80 is a non-billable header code. I80 groups more specific codes and cannot be submitted on a claim. A valid ICD-10-CM code must be reported at the highest level of specificity available in its branch. Select one of the 39 billable codes beneath I80.

Excludes1 — never code together
The conditions below can never be reported together with I80 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.
Code first
The underlying condition below must be sequenced before I80. I80 describes a manifestation and cannot be the principal or first-listed diagnosis.
Includes
Conditions classified to I80.
- endophlebitis
- inflammation, vein
- periphlebitis
- suppurative phlebitis
Excludes2 — not included here — inherited from Chapter 9
The conditions below are not part of I80, but a patient may have both at the same time. When documentation supports it, I80 and the excluded code may both be reported.
- certain conditions originating in the perinatal period (P04-P96)
- certain infectious and parasitic diseases (A00-B99)
- complications of pregnancy, childbirth and the puerperium (O00-O9A)
- congenital malformations, deformations, and chromosomal abnormalities (Q00-Q99)
- endocrine, nutritional and metabolic diseases (E00-E88)
- injury, poisoning and certain other consequences of external causes (S00-T88)
- neoplasms (C00-D49)
- symptoms, signs and abnormal clinical and laboratory findings, not elsewhere classified (R00-R94)
- systemic connective tissue disorders (M30-M36)
- transient cerebral ischemic attacks and related syndromes (G45.-)

How long has I80 existed?
I80 has been in ICD-10-CM since at least FY2016, the earliest fiscal year on record here.
Derived from the official order files for FY2016–FY2026. FY2017 and FY2020 publish no order file, so those years are not covered.
