Use Code

## **What is HCPCS code L2275?** HCPCS code L2275, an L code, has a code description of: "Addition to lower extremity, varus/valgus correction, plastic modification, padded/lined." It refers to an orthotic addition involving a plastic mod low ext pad/line or plastic modification designed to correct varus (inward angulation) or valgus (outward angulation) deformities of the lower extremity. This addition incorporates padding and lining for enhanced comfort and alignment support. Clinically, it is applied to existing lower-limb orthoses when malalignment contributes to gait abnormalities or pain and when corrective stabilization via rigid plastic modification is indicated. By addressing alignment in multiple planes and providing cushioning, this adapted orthosis can improve functional mobility, reduce musculoskeletal strain, and support corrective alignment in patients with knee, ankle, or lower-leg deformities. It typically involves a fitting and modification process by an orthotist, integrating both structural correction and patient comfort considerations.

## **HCPCS code L2275 documentation requirements** Proper documentation is crucial for billing and reimbursement for L2275. Key requirements that a healthcare provider need to keep in mind generally include: - **Standard Written Order (SWO)**: A prescription from the treating practitioner (e.g., a physician or podiatrist for conditions below the ankle) that includes the patient's name, order date, a general description of the item, and the practitioner's signature. - **Medical necessity**: The patient's medical record must clearly justify the need for the device and its specific modifications. This includes a documented diagnosis of a knee or ankle deformity (e.g., varus or valgus); objective findings, such as a physical examination, gait analysis, or imaging studies (e.g., X-rays), that confirm the alignment issue; a description of the patient's condition that necessitates a custom modification to prevent tissue injury, or because the condition is expected to be permanent. - **Delivery documentation**: A delivery invoice or a shipping invoice that includes the patient's name, a description of the item, the delivery date, and a signature from the person accepting the delivery.

## **L2275 billing requirements** Billing for L2275 follows specific guidelines: - **Add-on code**: L2275 is an add-on code, meaning it's billed in addition to a base orthotic code (e.g., a knee-ankle-foot orthosis or an ankle-foot orthosis). It should not be billed as a standalone item. - **Custom fabrication**: This code is typically used for custom-fabricated orthoses, not prefabricated or off-the-shelf devices. The allowance for L2275 includes the evaluation, casting, and fitting/adjustments, so these services cannot be billed separately. - **Modifiers**: Depending on the specific situation, a payer may require modifiers. For example, some payers may require the use of the LT (left side) and RT (right side) modifiers to specify which limb was treated. Other modifiers, such as those related to a patient's functional ambulation level, may also be required for certain lower extremity prosthetic and orthotic codes. - **Frequency limits**: For pediatric patients, growth and development may necessitate more frequent replacements. The documentation must support the need for a new device due to anatomical changes.

## **Other relevant codes** - **L1900-L1990**: Ankle-foot orthoses (AFOs) - **L2000-L2192**: Knee-ankle-foot orthoses (KAFOs) - **L2270**: Addition to lower extremity, varus/valgus correction ("T") strap, padded/lined or malleolus pad - **L2280**: Addition to lower extremity, molded inner boot - **L2330**: Addition to lower extremity, lacer molded to patient model, for custom-fabricated orthosis only

Frequently asked questions

While both codes relate to varus/valgus correction, L2275 involves a plastic modification to the device, whereas L2270 uses a "T" strap, padded/lined or a malleolus pad. The choice of code depends on the type of modification performed.

No. Noridian policy explicitly prohibits using L2275 for Arizona-type custom-fabricated AFOs—use codes such as L2330 or L2820 instead depending on the design and interface elements.

Yes. As with all DMEPOS services, proof of delivery must be retained and available upon request—documentation that the addition was delivered appropriately is essential.
