81003 — Urinalysis, by dip stick, automated, without microscopy
A urine test using an automated machine to read a dipstick dipped in urine, measuring multiple chemical markers such as leukocytes, pH, specific gravity, and glucose without looking at the sample under a microscope.
- Typical setting: Hospital lab, reference lab, doctor's office
- National avg charge (illustrative): $3–$7 Medicare allowed (CMS CLFS); $5–$30 commercial; varies by region
- Most-disputed reason: Billing 81003 (automated) when the manual non-automated method (81002) was actually used

Common errors with this code
What goes wrong on real bills.

- Billing 81003 (automated) when the manual non-automated method (81002) was actually used
- Bundling issues: 81003 is included in 81001 (automated with microscopy) — cannot bill both for the same specimen
- Some payers require TC (technical component) modifier when performed in an office setting without a separate professional interpretation
If you see 81003 on your bill
Three steps before paying.
1. Get the itemized bill. If your statement only shows a summary, request the CPT-level itemized bill before paying. Generate the request language →
2. Cross-check against the EOB. Compare what your insurer's Explanation of Benefits says you owe versus what the hospital is asking. They disagree more often than people think. Read the bill-vs-EOB guide →
