TL;DR: The Centers for Medicare & Medicaid Services modified NCD 185 governing screening Pap smears and pelvic examinations for cervical and vaginal cancer detection, with an effective date of March 7, 2026. Here's what your billing team needs to know.
This update to the CMS Pap smear and pelvic exam coverage policy clarifies frequency rules, high-risk criteria, and documentation requirements for Medicare Part B billing. NCD 185 in the Medicare system covers both the screening Pap smear (including sample collection and physician interpretation) and the screening pelvic examination (including clinical breast examination). The policy does not list specific CPT or HCPCS codes — more on that below.

CMS Screening Pap Smear and Pelvic Exam Coverage Criteria and Medical Necessity Requirements 2026
NCD 185 is the National Coverage Determination governing Medicare's coverage of screening Pap smears and pelvic examinations for early cervical and vaginal cancer detection. This coverage policy applies to Medicare Part B and covers two distinct services: the screening Pap smear itself (including cell collection and physician interpretation) and the screening pelvic examination (including clinical breast examination).
The medical necessity standard here splits into two tracks: standard frequency and high-risk frequency. Understanding which track applies to your patient drives every downstream billing decision.
Standard frequency: Medicare covers one screening Pap smear every 24 months for women who don't meet high-risk criteria. A woman of childbearing age — defined as premenopausal and confirmed as such by a physician or qualified practitioner — is also eligible when she has had a Pap smear during any of the preceding three years that showed cervical or vaginal cancer or another abnormality.
High-risk frequency: Women who meet one or more high-risk criteria qualify for more frequent screening. Medicare covers these tests more often than every two years when the physician or authorized practitioner documents the risk. The five recognized high-risk factors are:
| # | Covered Indication |
|---|---|
| 1 | Early onset of sexual activity (under 16 years of age) |
| 2 | Multiple sexual partners (five or more 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 |
The real issue here is documentation. The policy requires that claims for Pap smears indicate the patient's low or high-risk status by including the appropriate diagnosis code on the line item — specifically Item 24E of the CMS-1500 form. Miss that, and you're looking at a claim denial regardless of whether the service was medically appropriate.
This coverage policy also extends to qualified non-physician practitioners. Certified nurse midwives, physician assistants, nurse practitioners, and clinical nurse specialists can order these screenings — provided they are authorized under state law to perform the examination. That's a meaningful reimbursement consideration for practices where NPs and PAs handle women's health screenings.
Prior authorization is not required under this NCD for Medicare Part B. But frequency limits function as a hard stop. A claim for a screening Pap smear that falls inside the 24-month window without documented high-risk status will deny. Don't rely on the plan to catch it upstream — your billing team needs to verify eligibility and prior Pap smear history before the claim goes out.
CMS Screening Pelvic Exam Coverage Criteria and Medical Necessity Requirements 2026
The screening pelvic examination under NCD 185 is a separate covered service from the Pap smear, though the two are often performed together. Section 4102 of the Balanced Budget Act of 1997 established this benefit. It covers all female Medicare beneficiaries, subject to frequency limits.
The medical necessity standard for the pelvic exam is structural: the exam must include at least seven of the following 11 elements to qualify for coverage.
- Inspection and palpation of breasts for masses or lumps, tenderness, symmetry, or nipple discharge
- Digital rectal examination — sphincter tone, hemorrhoids, 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 out of 11. That threshold matters. If your providers document fewer than seven elements, the claim is at risk. This is a common audit finding in women's health practices — the pelvic exam gets billed, but the documentation doesn't support the full element count. Build the 11-element checklist into your encounter templates now if it isn't already there.
Coverage Indications at a Glance
| Indication | Status | Relevant Codes | Notes |

| Screening Pap smear, woman of childbearing age with prior abnormal Pap within 3 years | Covered | Not specified in NCD 185 — verify with your MAC | Physician or qualified practitioner must confirm childbearing age status |
| Screening Pap smear, high-risk woman, more frequent than every 2 years | Covered | Not specified in NCD 185 — verify with your MAC | Must document qualifying high-risk factor; include high-risk diagnosis code on Item 24E |
| Screening pelvic exam (including clinical breast exam) with at least 7 of 11 required elements | Covered | Not specified in NCD 185 — verify with your MAC | Documentation must support all billed elements |
| Screening pelvic exam with fewer than 7 of 11 required elements documented | Not Covered | — | Insufficient documentation; risk of claim denial on audit |
| Pap smear ordered by unauthorized practitioner | Not Covered | — | Ordering provider must be a physician, CNM, PA, NP, or CNS authorized under state law |
| Screening Pap smear within 24-month window without documented high-risk status | Not Covered | — | Frequency limitation applies; no prior authorization bypass available |
CMS Pap Smear and Pelvic Exam Billing Guidelines and Action Items 2026
The effective date of March 7, 2026, means your billing team should be reviewing workflows now — not after your next Medicare audit. Here are the specific steps to take.
1. Audit your CMS-1500 templates for Item 24E compliance.
Every claim for a Medicare screening Pap smear must carry the appropriate diagnosis code on line item 24E indicating low or high-risk status. Check your billing software configuration to confirm this field is populated before submission. A missing or mismatched risk-status code is a fast path to a claim denial.
2. Build or update your high-risk screening criteria checklist.
Train your front-end staff and providers on the five high-risk factors. The patient's chart needs to document the specific qualifying factor — not just a checkbox that says "high risk." Auditors will look for the supporting clinical evidence.
3. Verify frequency eligibility before submitting claims.
Pull the patient's Medicare claims history to confirm no Pap smear was billed within the prior 24 months for low-risk patients. For high-risk patients, confirm the documented qualifying factor is on file and the ordering provider's recommendation is in the chart.
4. Confirm your pelvic exam documentation hits seven of 11 elements.
Review your EHR's physical exam templates for the screening pelvic exam. Count the elements. If your standard template covers fewer than seven, update it before March 7, 2026. This isn't a gray area — seven is the floor for coverage.
5. Verify ordering provider credentials for non-physician practitioners.
When a PA, NP, CNM, or CNS orders or performs a screening Pap smear, confirm they are authorized under your state's scope-of-practice laws to perform the examination. Medicare follows state law here. If your state restricts the scope for any of these provider types, the claim won't hold up.
6. Contact your Medicare Administrative Contractor for code-level guidance.
NCD 185 does not specify CPT or HCPCS codes. Your MAC issues local coverage determinations and billing guidelines that map specific procedure codes to this NCD. Contact your MAC directly, or check their LCD database, to confirm which codes to use for Pap smear billing and pelvic exam billing under this policy. Using the wrong code — or a code your MAC hasn't paired with this NCD — will trigger a denial.
If your practice has high volume in women's health screenings and you're unsure how your current billing setup maps to these requirements, talk to your compliance officer or billing consultant before the March 7, 2026 effective date. The documentation requirements here are specific enough that a pre-billing audit is worth the time.
| Previous Version | Current Version |
|---|---|
| Coverage is considered experimental and investigational for all indications | Coverage is considered medically necessary when specific criteria are met |
| Prior authorization is not required | Prior authorization is required for initial treatment |
| Documentation must include clinical history | Documentation must include clinical history |
| 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 Exams Under NCD 185
Important Note on Code Coverage
NCD 185 does not specify CPT, HCPCS Level II, or ICD-10-CM codes within the policy document itself. This is not unusual for older NCDs — code-level guidance lives at the MAC level, not the national level.
For Pap smear billing and pelvic exam billing under Medicare, your MAC's local coverage determination is the operative document for code selection. Each MAC may map different procedure codes to this NCD, and using a code outside your MAC's approved list will result in a claim denial.
What to Do
Contact your Medicare Administrative Contractor directly and request their current LCD and billing guidelines tied to NCD 185. Key questions to ask:
- Which CPT codes apply to screening Pap smear collection and physician interpretation under this NCD?
- Which CPT code covers the screening pelvic examination?
- What ICD-10-CM codes does your MAC accept to document low-risk and high-risk status (Item 24E)?
Do not assume that codes used under a commercial payer's Pap smear policy will map cleanly to Medicare. The benefit category and documentation standards are different.
