Billable/Specific Code

I51.3 is a billable/specific ICD-10-CM code that can be used to indicate a diagnosis for reimbursement purposes.

This is the American ICD-10-CM version of I51.3 - other international versions of ICD-10 I51.3 may differ.

Applicable To

Apical thrombosis (old)
Atrial thrombosis (old)
Auricular thrombosis (old)
Mural thrombosis (old)
Ventricular thrombosis (old)

Type 1 Excludes

Type 1 Excludes Help

A type 1 excludes note is a pure excludes. It means "not coded here". A type 1 excludes note indicates that the code excluded should never be used at the same time as I51.3. A type 1 excludes note is for used for when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.
