About coding renal artery thrombosis
The ICD-10-CM code for renal artery thrombosis is N28.0 (Ischemia and infarction of kidney). The official index lists 1 more specific code, so check the documentation for details such as type, cause, site or severity before settling on N28.0.
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.
