About coding venous sinus embolism
The ICD-10-CM code for venous sinus embolism is G08 (Intracranial and intraspinal phlebitis and thrombophlebitis).
Don't report G08 together with the conditions in its Excludes1 note: abortion, ectopic or molar pregnancy (O00-O07, O08.7), pregnancy, childbirth and the puerperium (O22.5, O87.3) and nonpyogenic intracranial phlebitis and thrombophlebitis (I67.6).
The conditions in its Excludes2 note aren't part of G08, but may be coded alongside it if the patient has both: intracranial phlebitis and thrombophlebitis complicating nonpyogenic intraspinal phlebitis and thrombophlebitis (G95.1).
As a secondary diagnosis it is an MCC (major complication or comorbidity), which can move an inpatient stay into the highest-paying "with MCC" MS-DRG of its family, unless the principal diagnosis excludes it.
Don't confuse with (Excludes1 for G08)
