• Refer to the coding and billing of custom fitted orthotics that do not have a corresponding off-the-shelf equivalent article by the Joint DME MAC and PDAC. Custom Fitted Orthotic HCPCS Codes Without a Corresponding Off-the-Shelf Code - Correct Coding

• A custom fabricated orthosis is one which is individually made for a specific beneficiary (no other beneficiary would be able to use this orthosis) starting with basic materials including, but not limited to, plastic, metal, leather, or cloth in the form of sheets, bars, etc. It involves substantial work such as vacuum forming, cutting, bending, molding, sewing, etc. It requires more than trimming, bending, or making other modifications to a prefabricated item.
• To support medical necessity of custom fabricated rather than a prefabricated orthosis, include detailed documentation in treating physician's records. This information will be corroborated by functional evaluation in orthotist or prosthetist's records and must be available upon request
• Billing Not Otherwise Classified (NOC) custom fabricated - If the item is custom fabricated and does not have a specific HCPCS code, a complete and clear description of the item, including what makes this item unique, and a breakdown of charges (material and labor used in fabrication) should be entered in the narrative field of an electronic claim or on Item 19 of a paper claim.

• Off-the-Shelf - Minimal self-adjustment refers to adjustments that can be made by the beneficiary, their caregiver, or the supplier, such as assembling, trimming, or adjusting straps. Minimal self-adjustment does not require any expertise in trimming, molding, assembling, or customizing to fit to the individual; therefore, the adjustment does not need to be performed by a certified orthotist or an individual with specialized training.
• Custom Fitted - More than minimal self-adjustment is when an item must be trimmed, bent, molded, or otherwise modified for an individualized fit. These kinds of alterations require the expertise of a certified orthotist or someone with specialized training in the provisions of orthoses to fit the item to the beneficiary.

• Off-the-Shelf - If an orthosis needs only minimal self-adjustment for fitting at the time of delivery, it is considered off-the-shelf.
• Custom Fitted - If an orthosis requires more than minimal self-adjustment, it is considered custom fitted. A certified orthotist or an individual who has equivalent specialized training can perform more than minimal modifications for a custom fitted prefabricated orthotic. (e.g., physician, treating practitioner, physical therapist, or occupation therapist in compliance with all applicable federal and state licensure and regulatory requirements). See article Definitions Used for Off-the-Shelf versus Custom Fitted Prefabricated Orthotics (Braces) - Correct Coding - Revised

• Need prior to surgery - Items can be provided and billed prior to surgery when item is medically necessary and the brace is required to be worn prior to surgery, coverage criteria is met, and documentation to substantiate the need is included in ordering physician’s medical record.
• Need after surgery - If there is no medical need to wear the brace until after surgery, item should not be provided until after the surgery has been performed and medical need exists.

• Allowed due to loss, theft, or irreparable damage or when reasonable useful lifetime (RUL) of original orthosis is met. RUL for DMEPOS items is five years unless specific LCD/PA specify otherwise
• See Medical Director written Billing Instructions - LSO and TLSO
• See Medical Director written Orthoses: Replacement of Components Clarification - Republished

• Suppliers must bill each item on two separate claim lines using the RT and LT modifiers and 1 UOS on each claim line. Claim lines for HCPCS codes requiring use of the RT and LT modifiers, billed without the RT and/or LT modifiers or with the RTLT on a single claim line, will be rejected as incorrect coding.

• Correct coding is an essential element for correct claim payment. The DME MACs and Pricing, Data Analysis and Coding (PDAC) contractor maintain a variety of resources to assist suppliers in determining the appropriate code for billing upper extremity braces. Please refer to the joint article, Correct Coding of Finger, Hand, Hand-Finger and Wrist-Hand- Finger Braces (Orthoses) - Revised and Correct Coding of Elbow, Shoulder, Shoulder-Elbow-Wrist-Hand and Shoulder- Elbow-Wrist-Hand-Finger Braces (Orthoses) for additional information.
