CPT 81002: Non-Automated Urinalysis Without Microscopy
CPT 81002 reports a urinalysis done with a dipstick or tablet reagent, read by eye, without microscopy. It is one of the few CLIA waived codes that does not need modifier QW. Medicare pays it under the clinical laboratory fee schedule, and the NCCI manual folds it into routine antepartum care.
Written by Salman Saeed, CEO and Co-Founder · Reviewed by a Certified Medical Coder · Last reviewed October 2026In short: 81002 is status X in RVU26D, paid from the lab fee schedule at 3.48 in the CY 2026 Q4 file, with an MUE of 2. CMS MLN article MM12841 lists it among the waived tests that do not require QW, and NCCI Chapter VII says antepartum care includes urinalysis.
What Does CPT 81002 Report?
81002 is a CPT code for a dipstick or tablet-reagent urinalysis that is read by eye and done without a microscope. One code covers the strip regardless of how many analytes the strip reports.
| Item | Value in the CMS files |
|---|---|
| Short label CMS uses | Urinalysis nonauto w/o scope |
| Physician fee schedule status (RVU26D, October 2026) | X, with no RVUs |
| Clinical lab fee schedule rate (CY 2026 Q4 file) | 3.48, one row, no QW row |
| NCCI MUE (Q4 2026 practitioner table) | 2, indicator 3, clinical data |
The related automated dipstick code 81003 is a different line: the same file lists it with a QW row and the same MUE of 2. For 81002 only the unmodified row exists.
Does 81002 Need Modifier QW?
No. The CMS MLN Matters article MM12841 says the tests on the first page of its list, including HCPCS codes 81002, 81025, 82270, 82272, 82962, 83026, 84830, 85013 and 85651, do not require a QW modifier to be recognized as waived.
The CY 2026 Q4 lab file agrees with that: it has a single 81002 row. Do not copy a QW habit from the strep and flu lines onto a dipstick line. The sibling tests 87880 and 87804 both have QW rows.
The testing site still needs a CLIA certificate. Chapter 16 section 70.8 lists the certificate types, and the CLIA number goes in box 23 of the CMS-1500.
Can 81002 Be Billed with an E/M Visit?
Usually, because the test and the visit are paid from different schedules. The visit goes to the physician fee schedule and the dipstick goes to the clinical laboratory fee schedule; RVU26D calls clinical diagnostic laboratory services a statutory exclusion from physician services.
There is one NCCI rule to know. Chapter VII, section G of the 2026 NCCI Policy Manual says antepartum care includes urinalysis, which is not separately reportable. A prenatal visit billed through the global obstetric package does not get an 81002 line. Outside that package, an office or urgent care visit such as 99213 can carry the test on a second line.
Nothing in the status or MUE data bars a visit and a dipstick on one date, but the NCCI procedure-to-procedure table has the final word, so run the pair through your claim scrubber. Put the reason for the test in the note, with the diagnosis pointed in box 24E.
How Does 81002 Sit on the CMS-1500?
81002 goes in box 24D of the CMS-1500 with units of 1 and no modifier for Medicare, with the CLIA number in box 23.
- Enter the visit on the first line.
- Enter 81002 on its own line, units 1, diagnosis pointer in box 24E.
- Add the CLIA number in box 23.
- Leave QW off for Medicare. A commercial payer that wants a modifier will say so in its manual.
What Should the Record Show for a Dipstick Test?
The record should show the result of the strip, the reason for the test and the CLIA number of the site that ran it. A strip result with no stated reason is the easiest line for a payer to question as not medically necessary.
Where the dipstick is a routine part of a visit type that a payer pays as a package, note which package it belongs to so the line is not read as a separate service.
Where Do the CLIA Number and QW Go on a Dipstick Claim?
A dipstick urinalysis is one line, 81002 in Item 24D with the QW modifier when the test is waived, and units in Item 24G. Chapter 26 says Item 23 carries the 10-digit CLIA certification number for lab services billed by an entity performing CLIA covered procedures. Item 24E points to the urinary symptom.
RVU26D gives 81002 status X, a statutory exclusion with no RVUs or payment amounts under the physician fee schedule, so payment comes from the lab fee schedule. The MUE table allows 2 per date with indicator 3.
Example: A patient with burning on urination has a dipstick test in the office on 10/09. The line is 81002 QW, pointer A (R30.0), 1 unit, $9.00, with the office's CLIA number in Item 23. A missing CLIA number is a common reason for CO-16.
Why Is 81002 Denied?
Dipstick denials come from the CLIA edit, from bundling and from the maternity rule.
| Code | What it says | Cause |
|---|---|---|
| CARC 16 with RARC MA120 | Claim lacks information or has a billing error; MA120 is a missing, incomplete or invalid CLIA certification number | No CLIA number in box 23 |
| CARC 97 | The benefit is included in the payment for another service already adjudicated | Antepartum or visit bundling |
| CARC 50 | Non-covered services because this is not deemed a medical necessity by the payer | No reason for the test in the note |
If these denials keep coming back, our denial management team can work them. See CO-16, CO-97 and laboratory billing.

01Can urinalysis 81002 be billed with an E/M visit?
Usually. The visit pays under the physician fee schedule and the test under the clinical laboratory fee schedule. The exception is antepartum care: Chapter VII of the 2026 NCCI Policy Manual says it includes urinalysis, which is not separately reportable. Run the pair through your edits.
02Does 81002 need modifier QW?
No. CMS MLN Matters MM12841 says HCPCS codes 81002, 81025, 82270, 82272, 82962, 83026, 84830, 85013 and 85651 do not require a QW modifier to be recognized as a waived test. The CY 2026 Q4 lab file has one 81002 row.
03What is the difference between 81002 and 81003?
81002 is a non-automated dipstick urinalysis without microscopy and 81003 is the automated version. The CY 2026 Q4 lab file has a single 81002 row at 3.48 and lists 81003 with a QW row, both with a Medicare MUE of 2.
04Is 81002 paid on the physician fee schedule?
No. RVU26D gives it status X, a statutory exclusion with no RVUs. Medicare pays it under the clinical laboratory fee schedule, which lists 3.48 for the code in the CY 2026 Q4 release, and assigned lab tests carry no deductible or coinsurance.
05How many units of 81002 are allowed?
The Q4 2026 Medicare practitioner MUE table gives 81002 a value of 2 with adjudication indicator 3, a date of service edit based on clinical data. One dipstick on one date is one unit, whatever number of analytes the strip reports.
