HCPCS Code A9270

Key Takeaways: HCPCS A9270

• Definition: A9270 is a miscellaneous code for “Non-covered item or service.” It is used to billing items excluded from coverage (e.g., convenience items, experimental devices).
• Outcome: Assigning A9270 to a claim line will almost always result in an automatic denial.
• Medicare Rule: A9270 is generally restricted to DME suppliers. Part A/B providers should not use it on standard claims unless instructed (e.g., with Condition Code 21).
• Modifiers: Use modifiers like GY (statutorily excluded), GA (ABN on file), or GL (medically unnecessary upgrade) to indicate liability.

HCPCS A9270 is a Level II code officially defined as a “Non-covered item or service.” It falls under the category of miscellaneous DME (Durable Medical Equipment) supplies and serves as a catch-all for products that Medicare and other payers do not cover. When providers use this code, they are effectively signaling that the item is excluded from benefits, and no payment is expected.

This guide explains when to use A9270, how to apply CMS rules, and which modifiers are critical for correct billing.

What is HCPCS A9270?

HCPCS A9270 is a “catch-all” code used when a healthcare item is furnished but is excluded from coverage. Assigning this code to a claim line item signals that the charge is non-covered under the payer’s rules.

It is primarily used to generate a formal denial, which is often necessary to bill a secondary insurer or to document patient liability.

When and Why is A9270 Used?

Common scenarios for using A9270 include:

• Statutorily Excluded Items: Items Medicare never covers by law (e.g., personal comfort items, hearing aids).
• Experimental Items: New devices without a specific HCPCS code. For example, in 2025, items like the “Q-Collar” neck device and certain cushions were billed with A9270.
• Deluxe/Convenience Features: Upgrades not medically necessary (e.g., custom paint on a wheelchair). Medicaid programs may require A9270 for these items.
• Wrong Category Items: Items that do not meet the definition of DME (e.g., vehicle-mounted wheelchair tie-downs, which should not be billed as K0108).

CMS Guidance for DME Suppliers

Warning: Code A9270 is generally not accepted on claims billed to Medicare Part A or Part B MACs. It is designated specifically for DME suppliers billing the DME MAC.

According to the Medicare Claims Processing Manual, A9270 should be used by suppliers only when an item has no specific code, no appropriate NOC code, and is statutorily non-covered.

Note for Part A Providers: Some MACs allow outpatient facilities to bill A9270 with Condition Code 21 (billing for denial) to receive a rejection notice for secondary billing.

Required Modifiers (GY, GA, GL, GX)

When billing A9270, you must attach a modifier to explain why it is non-covered and who is liable.

Using the correct modifier ensures the denial is processed correctly and protects the provider’s ability to bill the patient if an ABN was obtained.

Payer-Specific Rules

• Medicare (Traditional): Will deny A9270 automatically. Do not use on professional claims (use specific codes with GY/GZ modifiers instead).
• Medicaid: Varies by state. Some require A9270 for non-covered convenience items; others simply disallow the charge.
• Commercial Payers: Many recognize A9270 as a denial code, but some prefer generic supply codes (e.g., 99070) or proprietary “S” codes. Always check payer policy.

Common Billing Mistakes

• Using A9270 when a specific code exists: Always use a specific HCPCS/CPT code with a GY/GZ modifier if one exists. A9270 is a last resort.
• Billing on Part B claims: Doctors should avoid A9270 on professional claims; it will likely be rejected.
• Missing the ABN: If you expect a medical necessity denial, get an ABN signed and use modifier GA. Without it, you cannot bill the patient.
• Expecting Payment: A9270 is a zero-pay code with a payment indicator of “00”. Do not use it if you believe the item should be reimbursed.

Frequently Asked Questions (FAQ)

Q: Can a physician bill A9270 to Medicare?

A: Generally, no. Medicare Part B MACs do not accept A9270 on professional claims. Physicians should use the specific procedure/supply code with a GY or GZ modifier to indicate non-coverage.

Q: Does A9270 ever get paid?

A: No. A9270 is designed to be denied. It creates a record that the item was provided but is non-covered, which helps in billing secondary insurance or the patient.

Q: What modifier should I use if I have an ABN on file?

A: Use modifier GA. This tells Medicare you have a signed Advance Beneficiary Notice, allowing you to bill the patient after the denial.
