About coding Cylindruria
The ICD-10-CM code for Cylindruria is R82.998 (Other abnormal findings in urine).
Within R82.99, choose R82.998 (Other abnormal findings in urine) only when documentation doesn't support a more specific option: Hypocitraturia (R82.991), hyperoxaluria (R82.992), Hyperuricosuria (R82.993) and Hypercalciuria (R82.994).
Use an additional code to identify any retained foreign body, if applicable (Z18.-).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
