Urinalysis, automated, without microscopy
A standard automated urine dipstick test.
Based on typical US negotiated and cash-pay rates. Hospital charges can run significantly higher — often 2–10x these numbers. If your bill is well above this range, it's worth questioning.
- Billed alongside 81001 or 81002 — should be a single urinalysis code.
- Charged as a manual/microscopy test when only the machine was used.
You should see one urinalysis code per specimen, not stacked codes for the same sample.
