About coding Hyposplenism
The ICD-10-CM code for Hyposplenism is D73.0 (Hyposplenism).
Within D73 (diseases of spleen), D73.0 is specifically for Hyposplenism. Related codes cover Hypersplenism (D73.1), chronic congestive splenomegaly (D73.2), abscess of spleen (D73.3), cyst of spleen (D73.4), infarction of spleen (D73.5), other diseases of spleen (D73.8) and disease of spleen, unspecified (D73.9).
Don't report D73.0 together with the conditions in its Excludes1 note: asplenia (congenital) (Q89.01) and postsurgical absence of spleen (Z90.81).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
Don't confuse with (Excludes1 for D73.0)
