G08 — Intracranial and intraspinal phlebitis and thrombophlebitis
Is G08 billable?
Yes — G08 is billable for FY2027. G08 is a valid, billable ICD-10-CM code at the highest level of specificity in its branch. G08 may be submitted for encounters from October 1, 2026 through September 30, 2027.

Which MS-DRGs does G08 group to?
G08 sits in MDC 01 and helps define the logic of 2 MS-DRGs (version 44, FY2027). Which one a stay actually groups to also depends on procedures and secondary diagnoses.
- 023Craniotomy with Major Device Implant or Acute Complex CNS Principal Diagnosis with MCC or Antineoplastic Implant or Epilepsy with Neurostimulatorsurgical
- 024Craniotomy with Major Device Implant or Acute Complex CNS Principal Diagnosis without MCCsurgical
As a secondary diagnosis, G08 is a major complication or comorbidity (MCC), which can move a stay into a higher-paying DRG.
How is G08 listed in the Alphabetic Index?
These are the routes through the Alphabetic Index that lead to G08. They show the wording a clinician may have documented, which often differs from the Tabular description.
- Embolism › intraspinal venous sinuses or veins (multiple) (paradoxical)
- Embolism › venous sinus (multiple) (paradoxical)
- Phlebitis › intracranial (infective) (pyemic) (septic) (suppurative)
- Phlebitis › intraspinal venous sinuses and veins (infective) (pyemic) (septic) (suppurative)
- Thrombophlebitis › cavernoussinus
- Thrombophlebitis › cerebral
- Thrombophlebitis › intracranial venous sinus
- Thrombophlebitis › intraspinal venous sinuses and veins
- Thrombophlebitis › lateralsinus
- Thrombophlebitis › longitudinalsinus
- Thrombophlebitis › sinus
- Thrombosis, thrombotic › intraspinal venous sinuses and veins (bland) (multiple) (progressive) (silent) (vessel)
Excludes1 — never code together
The conditions below can never be reported together with G08 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.
Excludes2 — not included here
The conditions below are not part of G08, but a patient may have both at the same time. When documentation supports it, G08 and the excluded code may both be reported.
- intracranial phlebitis and thrombophlebitis complicating nonpyogenic intraspinal phlebitis and thrombophlebitis (G95.1)
Inclusion terms
Alternative wording in documentation that is classified to G08.
- Septic embolism of intracranial or intraspinal venous sinuses and veins
- Septic endophlebitis of intracranial or intraspinal venous sinuses and veins
- Septic phlebitis of intracranial or intraspinal venous sinuses and veins
- Septic thrombophlebitis of intracranial or intraspinal venous sinuses and veins
- Septic thrombosis of intracranial or intraspinal venous sinuses and veins
Excludes2 — not included here — inherited from Chapter 6
The conditions below are not part of G08, but a patient may have both at the same time. When documentation supports it, G08 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)
How long has G08 existed?
G08 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.
Which codes are confused with G08?
ICD-10-CM declares these codes mutually exclusive with G08 — exactly one of each pair can be correct for a given encounter.
