About coding bladder atrophy
The ICD-10-CM code for bladder atrophy is N32.89 (Other specified disorders of bladder). The official index lists 1 more specific code, so check the documentation for details such as type, cause, site or severity before settling on N32.89.
Within N32.8, choose N32.89 (Other specified disorders of bladder) only when documentation doesn't support a more specific option: Overactive bladder (N32.81).
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.
