About coding spleen necrosis
The ICD-10-CM code for spleen necrosis is D73.5 (Infarction of spleen).
Within D73 (diseases of spleen), D73.5 is specifically for infarction of spleen. Related codes cover Hyposplenism (D73.0), Hypersplenism (D73.1), chronic congestive splenomegaly (D73.2), abscess of spleen (D73.3), cyst of spleen (D73.4), other diseases of spleen (D73.8) and disease of spleen, unspecified (D73.9).
Don't report D73.5 together with the conditions in its Excludes1 note: rupture of spleen due to Plasmodium vivax malaria (B51.0) and traumatic rupture of spleen (S36.03-).
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 D73.5)
