Ob-Gyn Coding Alert

Question: The ob-gyn performs a level-two E/M for a new patient. The results of the evaluation lead the ob-gyn to suspect diabetes, so he performs a nonautomated dipstick urinalysis. Can we report both a urinalysis and an E/M code?

Answer: If the ob-gyn performs a lab test due to medical need to diagnose a suspected problem in addition to an E/M service for the same patient during the same encounter, you can typically report an E/M and a laboratory procedure code.

On the claim, report the following:

- 81002 (Urinalysis, by dipstick or tablet reagent for bilirubin, glucose, hemoglobin, ketones, leukocytes, nitrite, pH, protein, specific gravity, urobilinogen, any number of these constituents; non-automated, without microscopy) for the urinalysis

- 99202 (Office or other outpatient visit for the E/M of a new patient, which requires these three key components: an expanded problem-focused history; an expanded problem-focused examination; straightforward medical decision-making) for the E/M.

Modifier 25 alert: Depending on the payer, you may need to append the E/M with modifier 25 (Significant, separately identifiable E/M service by the same physician on the same day of the procedure or other service). Medicare does not require modifier 25 when you perform an E/M and a diagnostic test without a global period, but some payers might want modifier 25.

Best bet: Submit the claim using the insurer- required method. If you don't know a particular insurer's policy on this issue, contact a payer representative and ask before filing.
