TL;DR: The Centers for Medicare & Medicaid Services modified NCD 185, the national coverage determination governing screening Pap smears and pelvic examinations for early detection of cervical or vaginal cancer, with an effective date of March 7, 2026. Here's what billing teams need to do now.
This update to the CMS Pap smear and pelvic exam coverage policy refines how Medicare Part B covers these preventive services — and it has real teeth for claims that miss the diagnosis code requirements. The policy does not list specific CPT or HCPCS codes in this revision, but the medical necessity and documentation rules are detailed and specific. Get your charge capture and claim submission workflows aligned before March 7, 2026.

CMS Screening Pap Smear and Pelvic Exam Coverage Criteria and Medical Necessity Requirements 2026
NCD 185 in the CMS system covers two distinct but related preventive services under Medicare Part B: the screening Pap smear and the screening pelvic examination. Understanding which benefit category applies to your patient determines how you bill and what documentation you need.
For screening Pap smear billing, Medicare Part B covers the test — including sample collection and physician interpretation — when a physician or authorized practitioner orders it under one of two conditions. First, the patient has not had a Pap smear in the preceding two years, or she is a woman of childbearing age as defined in the policy. Second, her medical history or clinical findings show she is at high risk for cervical cancer, and her physician recommends more frequent testing than every two years.
The medical necessity threshold here is clear. If neither condition applies, the claim doesn't qualify under this coverage policy. Document which condition applies before you submit.
High-Risk Factors That Qualify a Patient for More Frequent Screening
The CMS Pap smear coverage policy defines high risk precisely. A patient qualifies as high risk if she meets at least one of these criteria:
| # | Covered Indication |
|---|---|
| 1 | Onset of sexual activity before age 16 |
| 2 | Five or more sexual partners in a lifetime |
| 3 | History of sexually transmitted disease, including HIV infection |
| 4 | Fewer than three negative Pap smears, or any abnormal Pap smear, within the previous seven years |
| 5 | DES (diethylstilbestrol) exposure — daughters of women who took DES during pregnancy |
This list is exhaustive under the NCD. If your patient doesn't meet one of these criteria, she does not qualify as high risk under this coverage policy. Billing her as high risk without documentation to support it is a path to claim denial and potential audit exposure.
How CMS Defines "Woman of Childbearing Age"
This definition matters for reimbursement. Under NCD 185, a woman of childbearing age is premenopausal and has been determined by a physician or qualified practitioner to be of childbearing age, based on medical history or clinical findings. She also must have had a Pap smear during any of the preceding three years that showed cervical or vaginal cancer, another abnormality, or she is at high risk of developing cervical or vaginal cancer.
This is not the same as simply being premenopausal. The definition links childbearing age status to prior testing history or documented risk. Make sure your documentation reflects that connection — not just an age notation in the chart.
Authorized Practitioners Under NCD 185
Pap smears ordered by certified nurse midwives, physician assistants, nurse practitioners, and clinical nurse specialists are covered — provided those practitioners are authorized under state law to perform the examination. This matters for practices that rely on advanced practice providers for preventive care visits. Verify state licensure scope before billing under the ordering provider's credentials.
CMS Screening Pelvic Exam Coverage Criteria and Medical Necessity Requirements 2026
The screening pelvic examination operates under a separate benefit category within NCD 185. Section 4102 of the Balanced Budget Act of 1997 established coverage for screening pelvic examinations — including a clinical breast examination — for all female Medicare beneficiaries, subject to frequency and documentation requirements.
The medical necessity standard for the pelvic exam is structural. The exam must include at least seven of eleven defined elements to qualify for coverage. This is a hard floor — not a guideline. If your documentation doesn't capture at least seven elements, you don't have a covered screening pelvic exam.
The Eleven Elements — Know All of Them
The CMS coverage policy specifies these eleven elements:
- Inspection and palpation of breasts for masses, lumps, tenderness, symmetry, or nipple discharge
- Digital rectal examination, including sphincter tone, hemorrhoids, and rectal masses
- External genitalia (general appearance, hair distribution, lesions)
- Urethral meatus (size, location, lesions, prolapse)
- Urethra (masses, tenderness, scarring)
- Bladder (fullness, masses, tenderness)
- Vagina (general appearance, estrogen effect, discharge, lesions, pelvic support, cystocele, rectocele)
- Cervix (general appearance, lesions, discharge)
- Uterus (size, contour, position, mobility, tenderness, consistency, descent, support)
- Adnexa/parametria (masses, tenderness, organomegaly, nodularity)
- Anus and perineum
Seven of eleven is the minimum. Document all elements performed, not just the ones that showed findings. Absent documentation of the element, an auditor treats it as absent from the exam.
Coverage Indications at a Glance
| Indication | Status | Relevant Codes | Notes |
|---|---|---|---|
| Screening Pap smear, low-risk patient, no smear in preceding two years | Covered | Policy does not specify codes | Must include low-risk diagnosis code on CMS-1500 line item 24E |
| Screening Pap smear, woman of childbearing age with prior abnormal result or high-risk status | Covered | Policy does not specify codes | Must include appropriate diagnosis code on CMS-1500 line item 24E |
| Screening Pap smear, high-risk patient, more frequent than every two years | Covered | Policy does not specify codes | High-risk status must be documented and supported by at least one qualifying factor |
| Screening pelvic examination with clinical breast exam, all female beneficiaries | Covered | Policy does not specify codes | Exam must include at least seven of eleven defined elements; frequency limitations apply |
| Pap smear ordered without physician or authorized practitioner order | Not Covered | — | Authorized practitioners include CNMs, PAs, NPs, CNSs with state law authorization |
| Pap smear without low- or high-risk diagnosis code on claim line | Claim Denial Risk | — | NCD 185 explicitly requires diagnosis code on line item 24E of CMS-1500 |
| High-risk Pap smear billed without documented qualifying risk factor | Claim Denial Risk | — | All five high-risk criteria are defined; documentation must support the one(s) applied |
CMS Screening Pap Smear and Pelvic Exam Billing Guidelines and Action Items 2026
This policy has a specific, non-negotiable claim submission requirement that causes preventable denials every year. The fix is not complex, but it requires process discipline.
| # | Action Item |
|---|---|
| 1 | Audit your claim submission template for CMS-1500 line item 24E before March 7, 2026. NCD 185 requires that every Pap smear claim include the appropriate low- or high-risk diagnosis code on the line item — not just in the header. If your billing system doesn't populate 24E at the line level, this is a configuration issue to solve now. |
| 2 | Build a hard stop in your charge capture for high-risk Pap smear claims. Before any high-risk claim goes out, a staff member should confirm that the chart contains documentation of at least one qualifying high-risk factor. The five qualifying factors are defined in the NCD. "Physician noted high risk" is not sufficient — the chart must show which factor applies. |
| 3 | Train your clinical documentation team on the seven-of-eleven element rule for pelvic exams. This is where pelvic exam claims fall apart on audit. If your providers document "pelvic exam performed" without element-level detail, you're exposed. The note should reflect each element examined, with findings or notation of normal findings. |
| 4 | Verify that your advanced practice providers are documented correctly as ordering practitioners. CNMs, NPs, PAs, and CNSs can order covered Pap smears — but only if state law authorizes them to perform the examination. Check your credentialing files and confirm state scope-of-practice authorization for each provider type in your practice. |
| 5 | Review frequency tracking for low-risk patients. Low-risk patients qualify for coverage every two years. If your scheduling or EHR system doesn't flag previous Pap smear dates for Medicare patients, you risk billing a second claim before the two-year window closes. That's a claim denial waiting to happen. |
| 6 | Confirm childbearing age determinations are documented in the chart, not just assumed. A premenopausal patient is not automatically a "woman of childbearing age" under NCD 185. The practitioner must make that determination based on medical history or clinical findings and document it. If your workflow doesn't capture this, update your intake or pre-visit documentation process. |
| 7 | If you're unsure how this policy applies to your patient mix or billing system configuration, talk to your compliance officer before the effective date of March 7, 2026. The diagnosis code requirement on 24E is the most common failure point, and it's also the most auditable. |
| Previous Version | Current Version |

| Re-review every 24 months | Re-review every 12 months with updated clinical documentation |
CPT, HCPCS, and ICD-10 Codes for Screening Pap Smears and Pelvic Examinations Under NCD 185
Covered Codes
The NCD 185 policy document, as provided in this revision, does not list specific CPT or HCPCS codes. This is common for national coverage determinations that predate current code sets or that defer code-level specificity to Medicare Administrative Contractor (MAC) local coverage determination guidance.
To identify the correct billing codes for screening Pap smear and pelvic exam services under NCD 185, check with your MAC directly. MACs publish LCD-level billing guidance that maps NCD criteria to current CPT and HCPCS codes. Your MAC's website is the authoritative source for the code-level detail this NCD doesn't supply.
| Code | Type | Description |
|---|---|---|
| Not specified in this policy revision | — | Refer to your MAC's local coverage guidance for current CPT and HCPCS code assignments |
Key ICD-10-CM Diagnosis Codes
NCD 185 does not enumerate specific ICD-10-CM codes in this revision. However, the policy explicitly requires that low-risk or high-risk diagnosis codes appear on line item 24E of the CMS-1500. Your MAC's companion documentation will list the accepted ICD-10-CM codes for low-risk and high-risk status. Use those exact codes — not free-text or unlisted codes — to meet the line-item requirement.
The real issue here is that without the right diagnosis code at the line level, your claim is non-compliant with NCD 185 regardless of clinical appropriateness. Pull your MAC's code list, build it into your charge master, and stop relying on coders to remember it claim by claim.
