HCPCS code L0113 – Cranial cervical orthosis for torticollis

Key takeaways

HCPCS Code L0113 covers a prefabricated torticollis-type cranial cervical orthosis, and its fee includes fitting and adjustment.

L0112 is the custom fabricated congenital torticollis code, so a prefabricated device belongs under L0113.

Medicare Part B covers L0113 as Durable Medical Equipment when medical necessity is documented and the applicable LCD criteria are met.

Modifier KX is required to confirm LCD criteria are satisfied; GA is required when an Advance Beneficiary Notice is on file.

Pabau’s claims management software keeps clinical documentation and billing records together, so an L0113 claim can be defended at audit.

HCPCS Code L0113: definition and official descriptor

HCPCS Code L0113 is an HCPCS Level II L-code for a prefabricated cranial cervical orthosis of the torticollis type. The Centers for Medicare and Medicaid Services (CMS) maintains HCPCS Level II codes, and those codes cover durable medical equipment, orthoses, prostheses, and supplies billed to Medicare and most Medicaid programs.

CMS defines L0113 as: Cranial cervical orthosis, torticollis type, with or without joint, with or without soft interface material, prefabricated, includes fitting and adjustment.

Two elements of that descriptor are optional. For example, the device may carry a joint or not, and a soft interface or not, and still bill under L0113. What stays fixed is the prefabricated build, and the fee already covers fitting and adjustment.

L-codes sit within the HCPCS Level II orthotic procedure range (L0100-L4999). L0113 belongs to the cervical orthosis run that starts at L0112, and every code in that run names a different device. So billing a plain cervical collar under L0113 invites denial, because the device supplied has to match the descriptor it is billed under.

Medicare coverage for L0113

Medicare Part B covers HCPCS Code L0113 under the Durable Medical Equipment benefit when the device is medically necessary for the beneficiary’s diagnosed condition. However, coverage is subject to the applicable Local Coverage Determination (LCD) issued by the beneficiary’s DME MAC (Medicare Administrative Contractor). Specifically, two contractors run the four DME MAC jurisdictions: Noridian Healthcare Solutions runs Jurisdictions A and D, while CGS Administrators runs Jurisdictions B and C. Either way, verify the coverage criteria with whichever contractor serves your jurisdiction before billing.

The coverage chain runs from the ordering physician’s face-to-face evaluation, through the written order, to the DME supplier’s claim submission. If any one of those steps is missing from the record, the claim is denied. So, before the device is dispensed, check that the beneficiary’s Part B DME benefit is active, and confirm that no prior authorization requirement applies.

Key Medicare coverage requirements for L0113 typically include:

• A physician or qualified non-physician practitioner (NPP) order specifying the orthosis
• A face-to-face clinical evaluation documented in the medical record within the timeframe specified by the applicable LCD
• A confirmed diagnosis supported by an ICD-10-CM code that is an LCD-covered indication for a cranial cervical orthosis
• Clinical documentation establishing that the orthosis is necessary for the patient’s condition and that conservative treatment options have been considered
• For custom-fitted devices: a detailed written order (DWO) before dispensing

Coverage criteria may vary by MAC and are subject to change. So, always verify against the current LCD for your jurisdiction before you submit a claim.

L0113 fee schedule and reimbursement rates 2026

CMS updates the DMEPOS fee schedule every year. The CMS DMEPOS fee schedule file carries the current allowable amounts by HCPCS code, jurisdiction, and pricing type. So, L0113 is priced there, not on the physician fee schedule. The rows below describe the pricing types rather than the amounts, which vary by MAC region and change each calendar year. That said, practice management software like Pabau centralizes the billing documentation behind each claim and tracks what the payer does with it after submission.

Reimbursement amounts differ across MAC regions. For example, fees in areas such as Alaska and Hawaii, and in rural areas, may carry a different adjustment. So, before you quote a figure, pull the current allowable amount from the CMS DMEPOS fee schedule file for that year.

Applicable modifiers for HCPCS Code L0113

Modifier selection on an L0113 claim decides whether Medicare processes it as covered, non-covered, or conditionally covered. In fact, incorrect modifiers are one of the leading causes of denial on DME claims. So, refer to the LCD and MAC guidance that apply for modifier-specific requirements. The table below reflects common modifier usage for HCPCS Level II orthosis codes.

Omitting the KX modifier on a claim where LCD criteria are met typically results in an automatic denial. On the other hand, appending KX when the documentation does not support medical necessity creates fraud risk.

ICD-10-CM codes linked to HCPCS Code L0113

Medical necessity for L0113 requires a supporting ICD-10-CM diagnosis code that the LCD recognizes as a covered indication. So, code only the confirmed diagnosis documented in the clinical record. In other words, the ICD-10 code must align with the physician’s documented findings, not with the device supplied. The codes below are the torticollis and cervical spine diagnoses most often paired with L0113. Our ICD-10 code reference carries the full descriptor for each one. Before you submit, verify the covered diagnosis list against your DME MAC’s current LCD.

Crosswalk tables are reference guides, not coverage guarantees. So, the ICD-10 codes recognized as covered indications for L0113 come from the DME MAC’s LCD for spinal orthoses, not from a table. Because payer crosswalks from commercial sources may differ from the LCD-covered list, always check the LCD directly.

Documentation requirements for L0113 claims

Insufficient documentation is the single most common reason L0113 claims fail post-payment audit. So, medical billing compliance for DME orthoses requires documentation that is current, specific, and easy to trace from the clinical record to the claim. In practice, digital clinical forms built around each required data element lower the risk that an otherwise clean claim is rejected for missing evidence.

Required documentation for a compliant L0113 claim typically includes:

• Written order: A legible physician or qualified NPP order specifying L0113 (or the device description matching L0113), dated before dispensing
• Face-to-face evaluation: Clinical notes from a face-to-face encounter documenting the diagnosis, relevant examination findings, and medical necessity for the orthosis within the LCD’s required timeframe
• Diagnosis confirmation: Documentation of a covered ICD-10-CM diagnosis supported by objective clinical findings (range of motion measurements, imaging findings, neurological findings as applicable)
• Device necessity justification: Statement that the orthosis is necessary for the patient’s condition and that less intensive interventions were considered
• Custom or prefabricated determination: For a custom fabricated device under L0112, documentation of the measurements taken and of the fabrication or fitting performed
• Proof of delivery: A signed note from the beneficiary confirming they received the device, dated and including the device description

Documentation requirements may vary by MAC. So, review the LCD that applies and its policy article for the complete list your jurisdiction’s DME MAC requires.

L0113 or L0112: prefabricated against custom fabricated

L0113 is the prefabricated code. Its descriptor ends with “prefabricated, includes fitting and adjustment”, so a device fabricated for one patient does not belong under it. In contrast, the custom fabricated counterpart is L0112, which the descriptor limits to congenital torticollis and which requires an adjustable range of motion joint. Getting that fork wrong is the most expensive error on this code pair, because the allowable amounts differ, and so does the evidence a reviewer expects. The table below sets the two side by side.

When the correct code for a specific product is unclear, submit a PDAC (Pricing, Data Analysis and Coding) coding verification request before billing. Then, a PDAC decision gives you written proof of the HCPCS code for that device, and it stands up as a defense in audit.

Medicare reasonable useful lifetime rules for L0113

CMS applies a Reasonable Useful Lifetime (RUL) policy to covered orthoses and DME. For most cervical orthoses, the RUL is five years. So, Medicare generally does not cover a replacement inside that window unless specific conditions are met. Billing a replacement before the RUL expires without a strong enough reason is a common audit finding, and it can trigger an overpayment demand.

Replacement before the RUL may be covered in a few cases:

• The device is lost, stolen, or damaged beyond repair (with documentation of the loss or damage)
• The patient’s condition has changed such that the existing device no longer meets their clinical needs (documented by the ordering physician)
• Normal wear and tear has left the device unusable, and repair is not practical or cost-effective (documented by the DME supplier)

When billing a replacement L0113 before the five-year RUL, document the specific reason for early replacement in the clinical and billing record. Also, cite CMS RUL policy directly in your documentation. RUL timelines run from the date the original item was delivered, not from the order date or the payment date.

Related HCPCS codes to L0113

Choosing the wrong cervical orthosis code is a frequent source of claim edits. The codes below are the neighbors L0113 is confused with most often. They differ by how the device is built, not by the part of the body it supports. So, read each long descriptor against the device in front of you before you pick one. If you want to check them by code, the NLM HCPCS Level II lookup returns the complete descriptors.

The table below also carries each long descriptor in full, with the one detail that separates it from L0113.

A basic foam collar is L0120. So, billing it under L0113 is upcoding, and it carries serious compliance risk. Instead, match the code to the device, not to the reimbursement rate.

How Pabau keeps L0113 documentation audit-ready

Most DME suppliers hold an L0113 claim in three places at once. First, the order and the face-to-face note sit in the chart. Then the signed delivery receipt sits in a folder, and the claim sits in the billing system. So when a records request arrives two years later, someone has to piece the set back together.

Pabau keeps them on one patient record instead. The written order, the evaluation note, the covered ICD-10 code, and the proof of delivery all attach to the file the claim is built from. Our audit-ready claims management then submits the claim and tracks what the payer does with it.

The result is a claim you can answer for. So, every element a reviewer asks about is dated, attributable, and filed against the same patient. That way, answering a records request becomes retrieval, not rebuilding it from scratch.

Centralize your DME billing documentation

Pabau connects clinical notes, diagnosis codes, and billing records in one place. Your L0113 claims carry their documentation trail before they reach the payer.

Conclusion

An L0113 claim succeeds when three conditions hold at once. First, the device matches the long descriptor. Second, the diagnosis is an LCD-covered indication. Third, the documentation runs unbroken from the order to the proof of delivery. So, most denials trace back to one of those three failing, not to an eligibility problem or a rate dispute.

The practical discipline is short. First, set the code from the device, not from the diagnosis. Then check that diagnosis against the current LCD, and keep the documentation with the claim from the day it is dispensed.
