About coding urinary stream weak
The ICD-10-CM code for urinary stream weak is R39.12 (Poor urinary stream).
Within R39.1 (other difficulties with micturition), R39.12 is specifically for poor urinary stream. Related codes cover hesitancy of micturition (R39.11), splitting of urinary stream (R39.13), Feeling of incomplete bladder emptying (R39.14), urgency of urination (R39.15), Straining to void (R39.16) and other difficulties with micturition (R39.19).
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.
