Clinical notes
Code first
This code represents a manifestation of an underlying disease. Coding convention requires the underlying (etiology) code to be sequenced first, with this code listed second.
Excludes2 (not included here)
An Excludes2 note means the excluded condition is not part of this one, but a patient can have both at the same time — in that case both codes may be reported together.
- atheroembolism (I75.-)
- basilar embolism and thrombosis (I63.0-I63.2, I65.1)
- carotid embolism and thrombosis (I63.0-I63.2, I65.2)
- cerebral embolism and thrombosis (I63.3-I63.5, I66.-)
- coronary embolism and thrombosis (I21-I25)
- mesenteric embolism and thrombosis (K55.0-)
- ophthalmic embolism and thrombosis (H34.-)
- precerebral embolism and thrombosis NOS (I63.0-I63.2, I65.9)
- pulmonary embolism and thrombosis (I26.-)
- renal embolism and thrombosis (N28.0)
- retinal embolism and thrombosis (H34.-)
- septic embolism and thrombosis (I76)
- vertebral embolism and thrombosis (I63.0-I63.2, I65.0)

Documentation support
General coding-documentation guidance — not a substitute for payer-specific requirements or professional coding judgment.
- •This is a non-billable header code. Documentation must support a more specific child code before this diagnosis can be reported on a claim.
- •This code represents a manifestation. Documentation should identify the underlying condition, which must be coded first.
- •As a general rule, code to the highest level of specificity supported by the documentation in the medical record.
