HCPCS code A4562 – Reusable non-rubber pessary

Key takeaways

A4562 covers a reusable, non-rubber pessary of any type, usually silicone. A4561 covers a reusable rubber pessary, so the material recorded in the chart decides the code.

Medicare Part B claims for A4562 go to the A/B MAC with fitting code CPT 57160, not to a DME MAC. A4562 is carrier-priced, with no DMEPOS fee schedule amount.

No KX modifier or pessary LCD applies to A4562. Use GA, GX, GY or GZ only when Medicare coverage is in doubt.

Pair the claim with a documented diagnosis, such as N81.x pelvic organ prolapse, N39.3 stress incontinence or N39.46 mixed incontinence.

Pabau, the practice management platform we build, keeps the fitting note and ABN on the patient record. Its claims management submits and tracks claims built from that record.

HCPCS Code A4562: official descriptor and classification

HCPCS Code A4562 is one of the HCPCS Level II codes, an alphanumeric supply code in the A-range. It is maintained by the Centers for Medicare and Medicaid Services (CMS) HCPCS Workgroup. The official descriptor is Pessary, reusable, non rubber, any type. It covers the device only. The fitting bills separately as CPT 57160, and Medicare Part B claims for both go to the A/B MAC.

The A-range covers medical and surgical supplies. A4562 sits alongside A4561 (rubber pessary) as a supply code, so it covers the device itself. The clinical service of fitting or managing it is a separate charge. Billers often conflate the two. They need separate claim lines, each supported by the chart note.

A4562 vs A4561: choosing the right pessary code

A4561 and A4562 share the same structure, and only the material separates them. Both describe a reusable device. A4561 is a rubber pessary and A4562 is any non-rubber pessary.

Before submitting, confirm the material type documented in the medical record. If the chart says “silicone ring pessary,” the correct code is A4562. Billing A4561 for a silicone device is a coding error, and it needs a corrected claim.

Check whether the device is reusable, too. A single-use pessary fits neither code, because CMS lists it separately as A4564, “Pessary, disposable, any type.” The diagram below maps all three codes and the claim path for A4562.

Clinical indications and required ICD-10-CM codes

Medicare and most commercial payers require documented medical necessity before covering a pessary supply. The treating physician’s notes must establish one of the accepted clinical indications, and the matching ICD-10-CM code must appear on the claim.

Accepted clinical indications

• Pelvic organ prolapse (uterine, vaginal vault, cystocele, rectocele)
• Stress urinary incontinence (SUI) and mixed urinary incontinence
• Uterovaginal prolapse in patients who are not surgical candidates

Required ICD-10-CM codes for A4562 claims

We found no Local Coverage Determination (LCD) that lists covered diagnoses for pessaries. The chart note therefore carries the medical necessity case on its own. Check commercial payer policies too, since some publish their own diagnosis lists.

How to bill HCPCS Code A4562: step-by-step

Billing A4562 correctly follows a set sequence before the claim reaches the A/B MAC. Skipping a step creates audit exposure. Understanding medical billing fundamentals for in-office supplies helps practices build a clean workflow from the start.

1. Confirm clinical indication. The treating physician documents the diagnosis, such as prolapse stage or stress urinary incontinence, in the medical record.
2. Document the fitting decision. The note records the pessary type, size and material, plus the fitting itself. Some commercial payers also ask for a separate written order.
3. Confirm device material. Verify the pessary is silicone or another non-rubber material, so A4562 (not A4561) is the correct code.
4. Select supporting ICD-10-CM codes. Pull the matching diagnosis codes from the physician’s documentation and link them to both claim lines.
5. Apply modifiers only where they fit. No KX modifier applies to A4562. If Medicare coverage is in doubt, issue an ABN and apply GA, GX, GY or GZ as appropriate. Other modifier use depends on the payer.
6. Submit to the A/B MAC. Bill A4562 and CPT 57160 together on the professional claim to the Part B MAC for your jurisdiction. A4562 is not on the DMEPOS jurisdiction list, so a DME MAC will not process it.
7. Retain documentation. Keep the chart note, the fitting record and any ABN in the patient file. Retain records per payer and CMS retention rules.

HCPCS Code A4562 modifiers

When coverage is in doubt, the modifier on an A4562 claim decides who carries the cost if Medicare denies. The table below covers the ABN modifiers, which apply only when Medicare coverage is in doubt. Confirm current guidance with your A/B MAC, because modifier policies change.

Most A4562 claims need no modifier at all, because no pessary LCD sets a KX requirement. GY tells Medicare the item is non-covered, so payment routes elsewhere. Applying GZ when you should have issued an ABN and used GA means the provider cannot recover payment from anyone.

Medicare coverage rules for A4562

Medicare Part B pays for A4562 through the A/B MAC when the practice supplies and fits the pessary. A4562 is carrier-priced, so each A/B MAC sets its own allowance. There is no DMEPOS fee schedule amount for it. Check the fitting fee for CPT 57160 in the CMS Physician Fee Schedule look-up tool before quoting an out-of-pocket estimate.

• Clinical documentation: The note records the decision to fit a non-rubber pessary, with its type, size and material.
• Medical necessity: The chart must document the covered diagnosis and support the ICD-10-CM code billed.
• Replacements: We found no LCD frequency limit for pessaries. Record the clinical reason for each replacement, such as damage or a size change.
• Contractor: A4562 does not appear on the DMEPOS jurisdiction list, so it bills to the A/B MAC for the practice’s location, not a DME MAC.
• ABN requirements: When coverage is in doubt, issue an Advance Beneficiary Notice of Noncoverage (ABN) to the patient before the pessary is fitted.

ABN requirements and modifier implications

An ABN protects the provider’s right to collect from the patient if Medicare denies the claim. Issuing it correctly matters as much as issuing it at all.

1. Identify the coverage uncertainty before dispensing the pessary, not after.
2. Complete the ABN form (CMS-R-131) with the specific reason coverage may be denied and an estimated cost.
3. Obtain the patient’s signature and a copy for the file.
4. Apply modifier GA on the claim if the ABN is on file and the patient accepted financial liability.
5. Apply modifier GX if you issued the ABN voluntarily on a potentially covered item.
6. Do not apply GZ when an ABN is on file. That modifier signals no ABN was issued, and it waives your right to patient payment.

Billing A4562 alongside the pessary fitting procedure

A4562 covers the device only. The clinical service of fitting and inserting the pessary bills separately under CPT 57160. Leave either line off and the practice loses that payment.

Both lines go on the same professional claim to the A/B MAC. A4562 pays the device, and CPT 57160 pays the fitting. If the visit also covers a separately identifiable problem, bill the E/M code with modifier 25.

Common claim denial reasons and how to fix them

Most A4562 denials trace back to a handful of root causes. Solid denial management workflows catch these before they reach the payer. Use the table below to identify the pattern and apply the corrective action before resubmission. OB-GYN and urogynecology practices should keep the fitting note and diagnosis on the same record, so it is ready if a claim is questioned.

Documentation checklist for A4562 claims

Work through this checklist before submitting every A4562 claim. Clean claim submission depends on fixing missing documentation before the claim reaches the payer, not after a denial letter arrives.

• Chart note records the decision to fit a non-rubber (e.g., silicone) pessary, with type and size
• Clinical documentation establishes a covered diagnosis (pelvic organ prolapse, SUI)
• Pessary material confirmed as non-rubber before selecting A4562
• ICD-10-CM code coded to full specificity and linked to both claim lines
• CPT 57160 billed on the same claim for the fitting
• Modifier 25 on the E/M line only if a separately identifiable visit is documented
• ABN issued and signed by the patient, on file (if coverage is in doubt)
• ABN modifier applied where relevant: GA (ABN on file), GX (voluntary ABN), GY (known non-covered), GZ (in doubt, no ABN)
• Claim sent to the A/B MAC, not a DME MAC
• Reason for any replacement pessary recorded in the chart

How Pabau supports pessary billing

Pessary claims depend on details recorded at the fitting: the material, the size, the diagnosis and any ABN. When those sit in different places, a coder has to chase them before the claim can go out.

Pabau keeps the fitting note, consent and ABN on the same patient record. Its claims management software submits claims built from that record and tracks their status. Billing staff can see what was sent and where each claim stands.

Practices running a pelvic health service can also use templated notes for pessary fittings and follow-up visits. Each review then records the same details, so the next claim starts from a complete note.

Keep pessary claims tied to the patient record

Pabau keeps the fitting note, the pessary details and any ABN on one patient record. Its claims management then submits and tracks the claim. See how it works for pelvic health practices.

Conclusion

A4562 is a practice-billed supply, and the routing decision follows from that. The pessary and its CPT 57160 fitting travel together on one claim to the A/B MAC. A DME MAC never sees it.

The judgment to keep is that the material decides the code, and the chart note decides the payment. Record the pessary type, size and diagnosis at the fitting, and the claim needs no special modifiers. Book a demo to see how Pabau keeps pessary fittings and claims on one record.
