About coding kidney granuloma
The ICD-10-CM code for kidney granuloma is N15.8 (Other specified renal tubulo-interstitial diseases).
Within N15, choose N15.8 (Other specified renal tubulo-interstitial diseases) only when documentation doesn't support a more specific option: Balkan nephropathy (N15.0), renal and perinephric abscess (N15.1) and renal tubulo-interstitial disease, unspecified (N15.9).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
In MS-DRG v44.0, it is part of the grouping logic for DRG 698 (Other Kidney and Urinary Tract Diagnoses with MCC, relative weight 1.6398), DRG 699 (Other Kidney and Urinary Tract Diagnoses with CC, relative weight 1.0003) and DRG 700 (Other Kidney and Urinary Tract Diagnoses without CC/MCC, relative weight 0.6741), in MDC 11 (Diseases and Disorders of the Kidney and Urinary Tract), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
