What is Modifier AV?

Modifier AV identifies certain items that are furnished in conjunction with a prosthetic device, prosthetic, or orthotic. The modifier helps Medicare determine the appropriate benefit category and payment treatment for items that may have different uses depending on the equipment or supplies with which they are furnished.

The same HCPCS item may sometimes be used with different types of medical equipment. Modifier AV communicates that the particular item reported on the claim is being furnished specifically for use with a qualifying prosthetic or orthotic.

Modifier AV does not independently establish Medicare coverage. The underlying item, prosthetic or orthotic, medical necessity, documentation, and other applicable coverage requirements must still be satisfied.

When to Use Modifier AV

Item Furnished With a Prosthetic Device: Modifier AV may be appropriate when an eligible item is supplied specifically for use with a covered prosthetic device.

Item Furnished With a Prosthetic: Applicable supplies or accessories furnished in conjunction with a prosthetic may require AV when Medicare coding instructions specify its use.

Item Furnished With an Orthotic: Modifier AV may identify an applicable item furnished for use with a qualifying orthotic.

HCPCS Code Supports AV: The underlying HCPCS code must be one for which Modifier AV is appropriate under applicable Medicare billing and DMEPOS requirements.

Relationship Is Documented: The supplier's records should establish that the item reported with AV was actually furnished for use with the qualifying prosthetic or orthotic.

When NOT to Use Modifier AV

Unrelated Medical Supply: Do not append AV simply because the beneficiary uses a prosthetic or orthotic. The reported item must actually be furnished in conjunction with it.

Item Furnished With Urological Supplies: Modifier AU, rather than AV, may apply to eligible items furnished in conjunction with urological, ostomy, or tracheostomy supplies.

Item Furnished With Surgical Dressings: Modifier AW may apply when an eligible item is furnished in conjunction with a surgical dressing.

Unsupported HCPCS Code: Modifier AV should not be automatically appended to every supply or accessory associated with prosthetic or orthotic care. The particular code and circumstances must support its use.

No Supporting Documentation: Do not use AV when the records cannot establish the relationship between the billed item and the prosthetic or orthotic.

Billing Example

A Medicare beneficiary uses a covered prosthetic device and requires an eligible supply specifically for use with that device.

The supplier furnishes the item and determines that the applicable HCPCS code and Medicare billing instructions require Modifier AV because the item is being used in conjunction with the prosthetic.

The supplier reports the appropriate HCPCS code with Modifier AV and maintains documentation showing the relationship between the item and the beneficiary's prosthetic device.

Documentation Requirements

Associated Prosthetic or Orthotic: Documentation should identify the prosthetic device, prosthetic, or orthotic with which the reported item is being used.

Item Furnished: Records should clearly identify the specific supply or item provided to the beneficiary and correspond with the HCPCS code submitted.

Medical Need: Documentation should support why the beneficiary requires the item in connection with the prosthetic or orthotic.

HCPCS Code: Verify that the reported code is eligible for Modifier AV under applicable Medicare coding and coverage instructions.

Quantity and Frequency: Records should support the amount supplied and demonstrate compliance with applicable utilization or replacement requirements.

Required Orders: Maintain applicable prescriptions, standard written orders, medical records, and other documentation required for the underlying item.

Billing and Claim Considerations

Modifier AV communicates the context in which an item is furnished. This can be important when the same HCPCS item can fall under different Medicare benefit or payment categories depending on its use.

Providers and suppliers should determine the actual purpose of the item before selecting AV. The beneficiary merely owning or using a prosthetic or orthotic does not establish that every related supply should receive the modifier.

The HCPCS code and modifier combination should accurately reflect the item furnished and its relationship to the prosthetic or orthotic.

Modifier AV does not override Medicare coverage requirements or guarantee reimbursement. The underlying item must still satisfy applicable medical necessity, benefit-category, documentation, utilization, and coding requirements.

Common Billing Mistakes

Automatically Reporting AV: Modifier AV should not be routinely appended to every item furnished to a beneficiary who uses a prosthetic or orthotic.

Using the Wrong Related Modifier: AU, AV, and AW describe different circumstances. The modifier should correspond with what the reported item is actually furnished in conjunction with.

Unsupported HCPCS Combination: Reporting AV with a HCPCS code that does not support the modifier under applicable billing instructions may cause incorrect claim processing.

Failing to Establish the Relationship: Documentation should demonstrate that the item was specifically furnished for use with the qualifying prosthetic or orthotic.

Incorrect Quantity Reporting: Billing quantities that exceed documented utilization or applicable coverage limits can result in denial even when AV itself is appropriate.

Assuming AV Establishes Coverage: The modifier identifies the item's use but does not independently demonstrate that Medicare covers the underlying item.

Common Denial Reasons

Incorrect Modifier: The payer determines that AV does not accurately describe how the reported item was furnished.

HCPCS Code Does Not Support AV: The modifier is reported with an item for which AV is not applicable under the relevant coding or coverage policy.

Relationship Is Not Documented: Records do not establish that the item was furnished in conjunction with a qualifying prosthetic device, prosthetic, or orthotic.

Medical Necessity Is Not Supported: Documentation does not demonstrate why the beneficiary requires the reported item.

Quantity or Frequency Is Not Supported: The amount billed exceeds applicable utilization requirements or is inconsistent with the beneficiary's documented needs.

Required Documentation Is Missing: Orders, medical records, proof of delivery, or other applicable documentation needed to support the claim is incomplete or unavailable.

Modifier AV vs. AU and AW

Modifier AV belongs to a group of modifiers used to distinguish how certain items are furnished.

Modifier AV identifies an applicable item furnished in conjunction with a prosthetic device, prosthetic, or orthotic.

Modifier AU identifies an applicable item furnished in conjunction with urological, ostomy, or tracheostomy supplies.

Modifier AW identifies an applicable item furnished in conjunction with a surgical dressing.

Selecting the correct modifier therefore depends on the item's actual use and the applicable Medicare billing requirements.
