Test Code3020
CPT Codes
81001
Includes
Macroscopic and Microscopic Examinations
If any of the following Urinalysis results are applicable, then a culture will be performed at an additional charge (CPT code(s): 87086).
•Presence of Leukocyte esterase alone
•Presence of WBC's (>5/hpf) alone
•Presence of Yeast
•Presence of Bacteria and the presence of WBCs (>5/hpf) or Leukocyte esterase
•Presence of Nitrite and the presence of WBCs (>5/hpf) or Leukocyte esterase
If culture is positive, CPT code(s): 87088 (each isolate) will be added with an additional charge. Identification will be performed at an additional charge (CPT code(s): 87077 or 87140 or 87143 or 87147 or 87149).
Antibiotic susceptibilities are only performed when appropriate (CPT code(s): 87181 or 87184 or 87185 or 87186).
Preferred Specimen
Submit two separate specimens:
1) 10 mL urine submitted in urinalysis transport tube (yellow-top, blue fill line, preservative tube)
2) 4 mL (fill to minimum line printed on tube; unpreserved for cultures) urine in urine culture tube (gray-top) or UriSponge™ transport

Other Acceptable Specimens
3 mL (1 mL minimum) unpreserved pediatric urine • 10 mL (3 mL minimum) urine collected in yellow-red swirl-topped conical transport tube with preservative

Encourage clean catch midstream samples to minimize contamination and improve accuracy. If sample is submitted unpreserved, please indicate that specimen is from pediatric patient (patient is less than or equal to 12 years of age). Label the sample appropriately. Unpreserved urine will be accepted from pediatric patients only.

Clinical Significance
Dipstick urinalysis is important in accessing the chemical constituents in the urine and the relationship to various disease states. Microscopic examination helps to detect the presence of abnormal urine cells and formed elements. Culture may identify the organism(s) causing infection.
