Medicare Mastectomy Coverage 2026: Codes, Limits, and How to File

A complete guide to every HCPCS code, allowable amount, and frequency limit for post-mastectomy products under Medicare Part B.

If you are a breast cancer survivor with Medicare, you have benefits specifically designed to cover the post-mastectomy products you need. The challenge is that almost nobody explains these benefits clearly. Instead, you get HCPCS codes, frequency limits, coverage criteria, and a maze of paperwork that makes you want to give up before you even start.

I do not want you to give up. I want you to understand exactly what Medicare covers, how much it pays, and how to get every dollar you are entitled to. So here it is: a plain-language, comprehensive guide to Medicare mastectomy coverage in 2026.

How Medicare Covers Post-Mastectomy Products

Post-mastectomy products are covered under Medicare Part B as prosthetic devices. They fall under the DMEPOS benefit, which stands for Durable Medical Equipment, Prosthetics, Orthotics, and Supplies. This is the same benefit category that covers items like artificial limbs, braces, and other medically necessary devices.

The key thing to understand is that Medicare treats breast prostheses and mastectomy bras as medical necessities, not cosmetic luxuries. After a mastectomy, these products are prescribed by your physician and covered by your insurance just like any other prosthetic device.

Your Cost-Sharing

After you meet your annual Part B deductible, Medicare covers 80% of the approved amount for each product. You are responsible for the remaining 20% coinsurance. If you have a Medigap (Medicare Supplement) plan, it may cover part or all of that 20%.

For example, if you receive a silicone breast prosthesis with a Medicare-approved amount of $268.31:

• Medicare pays: $214.65 (80%)
• You pay: $53.66 (20%)
• With Medigap: potentially $0 out of pocket

The Complete HCPCS Code Table for Post-Mastectomy Products

Here is every HCPCS code relevant to post-mastectomy products, along with the current Medicare allowable amounts, frequency limits, and what each product is.

L8000 -- Breast Prosthesis, Mastectomy Bra, Each

| Detail | Information | |---|---| | What it is | A standard mastectomy bra designed with built-in pockets to hold a breast prosthesis | | Medicare allowable amount | $52.42 | | Frequency limit | 6 per calendar year | | Requires prescription | Yes | | Coverage criteria | Must be post-mastectomy (partial or full). Bra must be specifically designed to hold a breast prosthesis. Must be prescribed by the treating physician. |

This is the code most women will use most often. Six bras per year means you can maintain a practical rotation: a few for daily wear, one for exercise, and one or two for dressier occasions. If your bras are losing elasticity, showing wear, or the pockets are no longer holding your prosthesis securely, it is time to use this benefit.

L8001 -- Breast Prosthesis, Mastectomy Bra, Custom Fitted, Each

| Detail | Information | |---|---| | What it is | A mastectomy bra that has been custom fitted to your specific body | | Medicare allowable amount | $135.58 | | Frequency limit | 6 per calendar year | | Requires prescription | Yes | | Coverage criteria | Post-mastectomy, custom fitted. Requires documentation that a standard bra does not fit due to body habitus or surgical outcome. Must include fitting by a certified fitter. |

The higher reimbursement rate reflects the additional expertise and time required for custom fitting. If your body shape, surgical outcome, or size falls outside standard ranges, your fitter can document the medical necessity for a custom-fitted bra. This documentation is essential for avoiding denials.

L8010 -- Breast Prosthesis, Mastectomy Sleeve, Each

| Detail | Information | |---|---| | What it is | A thin fabric sleeve that covers the breast prosthesis form, worn between the prosthesis and your skin | | Medicare allowable amount | $12.98 | | Frequency limit | 12 per calendar year | | Requires prescription | Yes | | Coverage criteria | Post-mastectomy. Used for comfort and hygiene when wearing prosthesis against skin. |

Sleeves are one of the most underused benefits. They keep your prosthesis clean, reduce skin irritation, absorb perspiration, and extend the life of your prosthesis. At 12 per year, you should always have fresh sleeves on hand. They are often billed alongside your prosthesis (L8030) as an accessory.

L8015 -- External Breast Prosthesis Garment, With Mastectomy Form, Post Mastectomy

| Detail | Information | |---|---| | What it is | An all-in-one garment that combines the bra and the prosthetic form in a single piece | | Medicare allowable amount | $210.76 | | Frequency limit | 2 per calendar year | | Requires prescription | Yes | | Coverage criteria | Post-mastectomy. Garment includes both the bra/garment and the prosthetic form built in. Prescribed by treating physician. |

These combination products are popular with women who prefer simplicity, especially for travel or active lifestyles. Instead of managing a separate bra and prosthesis, everything is integrated into one garment.

L8020 -- Breast Prosthesis, Mastectomy Form

| Detail | Information | |---|---| | What it is | A lightweight, non-silicone breast form, typically foam or fiberfill | | Medicare allowable amount | $117.64 | | Frequency limit | 1 per 12 months (initial); replacement every 2 years | | Requires prescription | Yes | | Coverage criteria | Post-mastectomy, initial or replacement. Lightweight form often used as an immediate post-surgical form before a permanent prosthesis is fitted. |

This is typically the first form you receive after surgery, sometimes called a "softie" or "puff." It is designed for the early healing period when your body is not ready for the weight and pressure of a silicone prosthesis. Many women continue to use lightweight forms alongside their silicone prosthesis for hot days, exercise, or sleeping.

L8030 -- Breast Prosthesis, Silicone or Equal, Each

| Detail | Information | |---|---| | What it is | A standard silicone breast prosthesis | | Medicare allowable amount | $268.31 | | Frequency limit | 1 per 2 years, per side | | Requires prescription | Yes | | Coverage criteria | Post-mastectomy. Must be prescribed by treating physician. Initial prosthesis covered after healing (typically 6-8 weeks post-surgery). Replacement every 2 years or sooner with documented medical need. |

This is the most commonly used code for permanent breast prostheses. The silicone form is designed to mimic the weight, movement, and feel of natural breast tissue. Your supplier must be enrolled in Medicare and meet DMEPOS quality standards.

If you need a replacement sooner than 2 years due to weight change, skin reaction, prosthesis damage, or change in your surgical site, your physician can document the medical necessity for early replacement.

L8031 -- Breast Prosthesis, Silicone or Equal, Custom Fabricated, Each

| Detail | Information | |---|---| | What it is | A custom-fabricated silicone breast prosthesis | | Medicare allowable amount | Varies by region and supplier (no standard national rate) | | Frequency limit | 1 per 2 years, per side | | Requires prescription | Yes | | Coverage criteria | Post-mastectomy. Requires documentation that a standard prosthesis cannot achieve acceptable fit or appearance. Custom fabrication must be performed by a qualified professional. |

Prior authorization may be required by some Medicare Administrative Contractors (MACs). Detailed documentation of medical necessity is essential. This code is used when standard off-the-shelf prostheses do not adequately address your surgical outcome.

L8032 -- Nipple Prosthesis, Prefabricated, Reusable, Any Type, Each

| Detail | Information | |---|---| | What it is | A reusable adhesive nipple prosthesis | | Medicare allowable amount | $10.57 | | Frequency limit | 2 per 6 months | | Requires prescription | Yes | | Coverage criteria | Post-mastectomy or breast-conserving surgery where nipple was removed. |

A small but meaningful product for many women. Nipple prostheses can be used with or without a breast prosthesis, and they provide a natural-looking finishing touch under clothing.

L8035 -- Custom Breast Prosthesis, Post Mastectomy, Molded to Patient Model

| Detail | Information | |---|---| | What it is | A breast prosthesis custom molded from a cast of your chest wall | | Medicare allowable amount | $594.72 | | Frequency limit | 1 per 2 years, per side | | Requires prescription | Yes | | Coverage criteria | Post-mastectomy. Requires documentation that standard and custom-fitted prostheses cannot achieve acceptable results. Typically for complex surgical outcomes. |

This is the highest reimbursement prosthesis code and requires a casting or molding process specific to your body. Prior authorization is strongly recommended before proceeding. This option is typically reserved for women whose chest wall shape, surgical outcome, or body type makes standard prostheses unsuitable.

L8039 -- Breast Prosthesis, Not Otherwise Specified

| Detail | Information | |---|---| | What it is | A catch-all code for breast prostheses that do not fit other specific codes | | Medicare allowable amount | Determined case by case | | Frequency limit | By report, determined individually | | Requires prescription | Yes | | Coverage criteria | Post-mastectomy. Requires detailed description, invoice, and medical justification. Subject to manual review. |

This code has a higher denial risk because it requires manual review. Use it only when no other specific code applies, and include thorough documentation of why other codes are not appropriate.

How to Verify Your Coverage

Before purchasing any post-mastectomy products, take these steps to confirm your coverage:

Call the number on the back of your Medicare card. Ask specifically about coverage for breast prostheses and mastectomy bras under Medicare Part B. Reference the HCPCS codes listed above. Ask about your remaining deductible and whether you have any supplemental coverage.

Confirm your supplier is Medicare-enrolled. The company you purchase from must be an enrolled DMEPOS supplier with CMS-approved accreditation. If they are not enrolled, Medicare will not pay the claim. You can verify enrollment on Medicare's supplier directory or simply ask the supplier directly.

Ask about prior authorization. For custom prostheses (L8031, L8035), some Medicare Administrative Contractors require prior authorization. Your supplier should know the requirements for your region's MAC. Getting prior authorization before you receive the product protects you from unexpected denials.

Required Documentation

Every Medicare claim for post-mastectomy products requires the following:

The Prescription (Written Order)

Your treating physician must provide a written order that includes:

• Your full name
• A description of the items prescribed (e.g., "mastectomy bra with pockets, bilateral" or "silicone breast prosthesis, left side")
• Your diagnosis code (most commonly Z90.10 through Z90.13 for acquired absence of breast and nipple, or Z85.3 for personal history of breast cancer)
• The physician's signature
• The date

The prescription must be received by the supplier before or at the time the products are delivered. A verbal order is not sufficient for Medicare DMEPOS claims.

Supplier Records

Your supplier is required to maintain records of the prescription, the fitting, and the products delivered. They must also be able to demonstrate that the products meet DMEPOS quality standards.

Common Denial Reasons and How to Avoid Them

Missing or incomplete prescription. This is the most common reason claims are denied. Make sure your prescription includes all required elements before your fitting appointment.

Supplier not enrolled in Medicare. If you purchase from a non-enrolled supplier, the claim will be denied regardless of how medically necessary the product is. Always verify enrollment first.

Exceeding frequency limits. Medicare has strict frequency limits for each code. If you request a new prosthesis before your 2-year replacement window, you need documented medical necessity from your physician explaining why early replacement is needed.

Insufficient documentation for custom products. Codes L8001, L8031, and L8035 all require documentation explaining why standard products are inadequate. Your fitter and physician must work together to provide this justification.

Using a "not otherwise specified" code without supporting detail. L8039 triggers manual review. Without a thorough explanation and supporting invoices, it will likely be denied.

Your Annual Benefit Summary

Here is an estimate of your maximum annual benefit if you use all available codes at their full frequency:

| Product | Code | Allowance | Annual Frequency | Annual Maximum | |---|---|---|---|---| | Standard mastectomy bra | L8000 | $52.42 | 6 | $314.52 | | Mastectomy sleeves | L8010 | $12.98 | 12 | $155.76 | | Prosthesis garment with form | L8015 | $210.76 | 2 | $421.52 | | Non-silicone form | L8020 | $117.64 | 1 | $117.64 | | Silicone prosthesis (per side) | L8030 | $268.31 | 1 per 2 years | $268.31 | | Nipple prosthesis | L8032 | $10.57 | 4 | $42.28 | | Estimated maximum annual benefit | | | | $1,320+ |

In years when a silicone prosthesis or custom prosthesis is replaced, the total can exceed $2,200. These are benefits you have earned. Do not leave them unused.
