ICD-10 code for thrombosis
I82.90

About coding thrombosis
The ICD-10-CM code for thrombosis is I82.90 (Acute embolism and thrombosis of unspecified vein). The official index lists 200 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on I82.90.
Within I82.9, choose I82.90 (Acute embolism and thrombosis of unspecified vein) only when documentation doesn't support a more specific option: chronic embolism and thrombosis of unspecified vein (I82.91).
Code first venous embolism and thrombosis complicating: abortion, ectopic or molar pregnancy (O00-O07, O08.7) and pregnancy, childbirth and the puerperium (O22.-, O87.-).
As a secondary diagnosis it is a CC (complication or comorbidity), which can move an inpatient stay into the "with CC" MS-DRG of its family, unless the principal diagnosis excludes it.
