About coding Paranephric abscess
The ICD-10-CM code for Paranephric abscess is N15.1 (Renal and perinephric abscess).
Within N15 (other renal tubulo-interstitial diseases), N15.1 is specifically for renal and perinephric abscess. Related codes cover Balkan nephropathy (N15.0), other specified renal tubulo-interstitial diseases (N15.8) and renal tubulo-interstitial disease, unspecified (N15.9).
As a secondary diagnosis it is an MCC (major complication or comorbidity), which can move an inpatient stay into the highest-paying "with MCC" MS-DRG of its family, unless the principal diagnosis excludes it.
In MS-DRG v44.0, it is part of the grouping logic for DRG 689 (Kidney and Urinary Tract Infections with MCC, relative weight 1.1415), DRG 690 (Kidney and Urinary Tract Infections without MCC, relative weight 0.801), DRG 791 (Prematurity with Major Problems, relative weight 4.1075) and DRG 793 (Full Term Neonate with Major Problems, relative weight 4.2195), in MDC 11 (Diseases and Disorders of the Kidney and Urinary Tract) and MDC 15 (Newborns and Other Neonates with Conditions Originating in the Perinatal Period), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
