CPT 81003 vs CPT 81025: How to Report in Global OB Period

Denial and bundling are common problems faced by OBGYN clinics that routinely conduct urinalysis and urine pregnancy testing during prenatal care. 

The reason is straightforward: both CPT 81003 and CPT 81025 are included in the global antepartum package under most payer policies when performed as routine prenatal care. Billing them separately without documented medical necessity produces CO-97 bundling denials or claim reductions.

This guide clarifies what each code applys to, if each is part of the global OB period or if each is separately billable, the documentation needed to support separate coding, and which modifiers to use with each code. 

What Is CPT 81003?

CPT 81003 is the code for an automated urinalysis without microscopy. Healthcare providers use this test to perform a chemical analysis of urine and evaluate multiple urine constituents in a single test. Depending on the patient's clinical presentation, the urinalysis may detect protein, glucose, blood (hemoglobin), leukocytes, nitrites, ketones, bilirubin, urobilinogen, pH, and specific gravity.

Unlike a microscopic urinalysis, CPT 81003 does not include microscopic examination of the urine sediment. If the provider determines that microscopy is medically necessary based on abnormal dipstick findings, a separate microscopy code may be reported when payer guidelines permit.

How Is CPT 81003 Performed?

CPT 81003 applies only to automated dipstick urinalysis. If the urine dipstick is performed manually rather than with an automated analyzer, a different CPT code should be reported instead.

CLIA Requirements for CPT 81003

Because CPT 81003 is a CLIA-waived laboratory test when performed on an approved waived analyzer, practices operating under a CLIA Certificate of Waiver may need to append modifier QW, depending on the payer's billing requirements.

Can CPT 81003 Be Split-Billed?

Modifiers 26 and TC may be used to bill separately for the professional and technical components of the CPT 81003 in certain facility settings. But it is always important for any provider to check any payer-specific rules first before reporting split components. 

Medicare Reimbursement for CPT 81003

The national Medicare payment for CPT 81003 is typically small, with payments averaging around $3 to $4, though payments differ by fee schedule, locality and payer. 

What Is CPT 81025?

CPT 81025 describes a qualitative urine pregnancy test performed by visual color comparison. The purpose of this test is to detect the presence of human chorionic gonadotropin (hCG) in urine to determine whether a patient is pregnant.

Unlike CPT 81003, this test evaluates only one analyte - hCG. It produces a qualitative result, meaning the outcome is reported as positive or negative rather than providing a numerical hormone level.

How Is CPT 81025 Performed?

CPT 81025 is performed by visually interpreting the reaction on a pregnancy test strip or testing device. It is not an automated laboratory analysis and does not involve microscopic examination or testing by a reference laboratory.

CLIA Requirements for CPT 81025

CPT 81025 is also classified as a CLIA-waived test, so the performing practice must maintain a valid CLIA Certificate of Waiver. Unlike some waived laboratory services, modifier QW is generally not required because Medicare already recognizes CPT 81025 as a CLIA-waived procedure.

Can CPT 81025 Be Split Billed?

No. CPT 81025 cannot be split billed. Modifiers 26, TC, and 99 should not be appended because the code does not have separate professional or technical components.

Medicare Reimbursement for CPT 81025

Generally Medicare will pay more for CPT 81025 than for CPT 81003, averaging about $8 to $11 nationally. Actual reimbursement will depend on the specifics of the particular payer and fee schedule. 

CPT 81003 During the Global OB Period

When CPT 81003 is administered during the global OB period as a part of routine prenatal care, it typically does not report separately. Urinalysis using a dipstick test is usually performed at a routine prenatal examination, which is part of the antepartum services provided within the global maternity package. That means providers shouldn't routinely bill CPT 81003 at each prenatal visit because many payers consider routine prenatal urinalysis to be part of the obstetric service code. 

Payer Guidance for CPT 81003

There are a few payers that have policies that support this approach. When performed in the office setting with an obstetric diagnosis, routine prenatal urinalysis is included in the global OB package, according to ACOG coding guidance and is considered to be UnitedHealthcare's routine prenatal urinalysis. 

Likewise, EmblemHealth states that CPT 81003 is not separately reimbursable when performed as routine prenatal screening. 

However, reimbursement may be allowed when the urinalysis is performed for a diagnostic purpose and the evaluation and management (E/M) service qualifies for Modifier 25, provided the documentation supports a significant, separately identifiable service.

When Can CPT 81003 Be Billed Separately?

CPT 81003 is typically bundled in the global OB, but may be used separately when the urinalysis is medically necessary to assess a new symptom, monitor an existing condition or investigate an abnormal finding. It should be apparent from the medical record that the test was administered for diagnosis not routine prenatal screening. 

Common clinical indications are:

• Symptoms of a urinary tract infection (UTI). 
• Dysuria or painful urination
• Hematuria
• Proteinuria requiring further evaluation
• Monitoring hypertension or suspected preeclampsia
• Glucose abnormalities or diabetes monitoring
• Flank pain
• Follow-up of a previously abnormal urinalysis

Does CPT 81003 Include Microscopic Urinalysis?

No. CPT 81003 only reports an automated urine dipstick analysis without microscopy. If the dipstick results are abnormal and the provider determines that a microscopic examination of the urine sediment is medically necessary, a separate microscopic urinalysis code may be reportable according to CPT coding rules and the payer's reimbursement policy.

Documentation Requirements for CPT 81003

During the global period for OB, the medical record should be clear on the medical necessity of performing the urinalysis so that the separation of the test and the procedure to obtain the urinalysis can be done without affecting reimbursement. 

• The reason the urinalysis was ordered beyond routine prenatal screening
• The patient's symptoms or clinical concern
• The urinalysis results
• The provider's assessment and treatment plan
• An appropriate pregnancy-related diagnosis code, when applicable
• A gestational age code (Z3A.XX) if required by the payer

CPT 81025 During the Global OB Period

Do not routinely bill 81025 during the global OB period once pregnancy has already been confirmed. Repeated pregnancy testing is generally not medically necessary during established prenatal care unless there is a separate clinical reason.

Payer Reference:  UnitedHealthcare explicitly lists CPT 81025 as a service included in the global obstetrical package for both vaginal and cesarean delivery. CPT codes 84702 and 84703 (serum pregnancy tests) are also listed as included. These codes will not be reimbursed separately when performed by the OB provider during the global OB period without documented medical necessity beyond confirmation of a known pregnancy.

When 81025 May Be Separately Reported

When pregnancy needs to be clinically verified, CPT 81025 may be separately coded. Acceptable scenarios are:

• Late period or irregular periods (no date of pregnancy is known) 
• Pregnancy confirmation visit at initial intake, before global OB period begins
• Positive home pregnancy test confirmation, if payer allows
• Pre-procedure pregnancy testing before a procedure requiring known pregnancy status
• Contraception-related visit, including IUD or Nexplanon insertion or removal
• Abnormal bleeding where pregnancy status is clinically uncertain

Documentation Required for Separate Billing of 81025

The chart must include:

• Reason for pregnancy testing, specifically why confirmation was clinically required
• Test result (positive or negative)
• Related diagnosis code supporting the clinical reason for testing
• Provider assessment and plan based on the test result

 

Modifier Guidance for CPT 81003 and CPT 81025

In most cases, no modifier will be used when reporting CPT 81003 or CPT 81025. These laboratory codes are typically chargeable without modifiers, unless otherwise specified by a payer policy.

When an Evaluation and Management (E/M) service is provided on the same date as either laboratory test, Modifier 25 should be appended to the E/M code, not to CPT 81003 or CPT 81025. Modifier 25 is appropriate only when the documentation supports a significant, separately identifiable E/M service in addition to the laboratory test.

For example:

99213-25

81003

It is important not to append Modifier 25 simply because a laboratory test was performed. The medical record must clearly support a separate evaluation and management service that is distinct from the work associated with ordering or performing the laboratory test.

Correct Billing Scenarios for CPT 81003 and CPT 81025 During the Global OB Period

The examples below illustrate the proper coding of CPT 81003 and 81025 in the global OB package as well as when they could be separately reported for medical necessity and documentation. 

Routine Prenatal Visit With No Separate Clinical Indication

A woman comes in for her 24 week prenatal checkup. The provider does a urine dipstick test as part of a routine prenatal exam. There is no urinary symptoms, abnormal findings, or other clinical concerns that would necessitate a diagnostic evaluation. 

Correct Billing

• Bill the appropriate global OB package (e.g., 59400 or 59510) according to the obstetric services provided.
• Do not report CPT 81003 separately, as the routine prenatal urinalysis is considered part of the global antepartum package.

Coding Tip: Billing CPT 81003 for every routine prenatal visit without documented medical necessity may result in CO-97 bundling denials and increase the risk of post-payment audits for unbundling.

Prenatal Visit With UTI Symptoms

At 28 weeks gestation a woman presents for a routine prenatal checkup and complains of dysuria and urinary frequency for the previous 2 days. The provider conducts an automated urinalysis to detect leukocytes and nitrites and makes a diagnosis of UTI (urinary tract infection). 

Correct Billing

• Report CPT 81003 separately because the urinalysis was performed to evaluate documented urinary symptoms.
• Report the appropriate diagnosis code for the UTI, along with the applicable pregnancy supervision or obstetric diagnosis.
• If the documentation supports a significant, separately identifiable E/M service, report the appropriate E/M code with Modifier 25.
• If the laboratory operates under a CLIA Certificate of Waiver, report 81003-QW when required.

Documentation Requirements

The medical record should contain:

• The symptoms of the patient, such as his urinary symptoms (dysuria and frequency) 
• The urinalysis findings
• The provider's assessment confirming the UTI
• The treatment plan
• Gestational age, when applicable

Preeclampsia or Hypertension Monitoring

A patient at 34 weeks of gestation with gestational hypertension returns for follow-up. During the visit, elevated blood pressure prompts the provider to perform a urinalysis to evaluate for proteinuria as part of the assessment for preeclampsia.

Correct Billing

Because the urinalysis is performed to evaluate a documented clinical condition rather than as routine prenatal screening, CPT 81003 may be reported separately.

The medical record should clearly document that the urinalysis was ordered to evaluate proteinuria associated with suspected preeclampsia or hypertension, along with the appropriate diagnosis code based on the documented findings.

Initial Pregnancy Confirmation Visit

A new patient comes in who has had a home pregnancy test and is now positive. provider does an office urine pregnancy test to confirm the pregnancy before the global OB period has been determined. 

Correct Billing

• CPT 81025 may be reported separately because the pregnancy confirmation occurs before the global OB package begins.
• Report the appropriate diagnosis code for a positive pregnancy test.
• Documentation should include the reason for testing, the test result, and the provider's assessment and plan.

Coding Tip: Once pregnancy has been confirmed and routine prenatal care begins, CPT 81025 should not be reported again for routine prenatal visits unless a separate clinical indication exists.

Pre-Procedure Pregnancy Test Before IUD Insertion

Established patient is seen for IUD insertion. A urine pregnancy test is also done to ensure that the patient is not pregnant before the procedure is carried out. 

Correct Billing

Because the pregnancy test is performed before a contraceptive procedure and is not part of routine prenatal care, CPT 81025 is separately reportable.

Documentation should include:

• The clinical reason for performing the pregnancy test before the procedure
• The test result
• The IUD insertion performed during the visit
