Urinary catheter
Collect as follows:
1. Cleanse skin around catheter with 70% alcohol. Allow to dry.
2. Aseptically remove catheter being careful to avoid contamination with normal flora from skin or other body surfaces.

Day(s) Test Set Up
Monday through SundayTest Classification and CPT Coding
CPT Code:87076 - definitive identification, anaerobic; each isolate
87077 - definitive identification, aerobic; each isolate
87186 - MIC; each isolate
87070 - isolation and presumptive identification of isolates (anaerobic culture if appropriate)
Microbiology Coding:
Proper coding for MICROBIOLOGY tests depends on what procedures are actually performed which may depend on the organism(s) isolated. When a culture is initially set up, organism(s) may be isolated and a presumptive identification takes place. When/if an organism(s) grows, a definitive identification and possible MIC of each organism may be indicated.
