About coding Slowing
The ICD-10-CM code for Slowing is R39.198 (Other difficulties with micturition).
Within R39.19, choose R39.198 (Other difficulties with micturition) only when documentation doesn't support a more specific option: Need to immediately re-void (R39.191) and position dependent micturition (R39.192).
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 695 (Kidney and Urinary Tract Signs and Symptoms with MCC, relative weight 1.1139) and DRG 696 (Kidney and Urinary Tract Signs and Symptoms without MCC, relative weight 0.6679), 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.
