About coding kidney infarct
The ICD-10-CM code for kidney infarct is N28.0 (Ischemia and infarction of kidney).
Within N28 (other disorders of kidney and ureter, not elsewhere classified), N28.0 is specifically for ischemia and infarction of kidney. Related codes cover cyst of kidney, acquired (N28.1), other specified disorders of kidney and ureter (N28.8) and disorder of kidney and ureter, unspecified (N28.9).
Don't report N28.0 together with the conditions in its Excludes1 note: atherosclerosis of renal artery (extrarenal part) (I70.1), congenital stenosis of renal artery (Q27.1) and Goldblatt's kidney (I70.1).
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.
Don't confuse with (Excludes1 for N28.0)
