HCPCS code E0114: Non-wood underarm crutches

Key Takeaways

HCPCS code E0114 describes a pair of non-wood, adjustable or fixed underarm crutches with pads, tips, and handgrips billed under the DMEPOS fee schedule.

Medicare Part B covers E0114 when a physician prescribes crutches and the beneficiary has a documented condition impairing ambulation, per LCD L33733.

Billing without the correct modifier (NU, RR, or UE) or without a standard written order is the leading cause of claim denial for E0114.

Practice management software like Pabau helps DME suppliers and practice billers organize order, modifier, and delivery documentation internally, so claims are audit-ready before a biller or clearinghouse submits them.

DME suppliers billing crutches face a specific documentation trap: the physician order is on file, the crutches are delivered, and then the claim denies because the modifier is wrong or the ICD-10 code isn’t on the LCD’s approved list. HCPCS code E0114 is a straightforward code, but the coverage rules around it are easy to get wrong. This guide covers the code definition, 2026 Medicare fee schedule, applicable modifiers, supporting diagnosis codes, documentation checklist, and the most common denial patterns billers encounter.

HCPCS code E0114: definition and code details

HCPCS code E0114 describes crutches, underarm, other than wood, adjustable or fixed, pair, with pads, tips, and handgrips. This is a Level II HCPCS code maintained by the Centers for Medicare and Medicaid Services (CMS) and used by DME suppliers to bill for non-wood axillary crutches dispensed as a pair. The code is active for 2026 billing.

Several distinctions matter when selecting E0114 over an adjacent code. The non-wood material requirement eliminates aluminum crutches coded as wood equivalents. The pair billing means both crutches are included in a single claim line. And the “other than wood” designation explicitly excludes the wooden crutch codes in the same family. Practice management software like Pabau can flag these code-selection criteria at the point of entry, helping suppliers catch mismatches in their own records before a claim ever reaches a biller or clearinghouse.

Medicare coverage criteria for E0114

Medicare Part B covers HCPCS code E0114 when three conditions are met. The beneficiary must have a condition that impairs ambulation, a physician must prescribe the crutches in a written order, and the specific crutch type must be medically appropriate for that patient. These criteria come directly from LCD L33733 (Canes and Crutches), the CMS Local Coverage Determination that governs E0114 claims across Medicare Administrative Contractor (MAC) jurisdictions.

LCD L33733 specifies that crutches are covered when a cane is insufficient to support the beneficiary’s weight-bearing limitations. Patients who can bear partial weight on both legs but need bilateral upper-extremity support are the typical clinical profile for E0114. Physical therapy practices that regularly prescribe mobility aids need the same documentation discipline for their own DME orders.

• Ambulatory impairment: The beneficiary’s medical record must document a condition that significantly limits their ability to walk without assistive support.
• Physician written order: A physician, nurse practitioner, or physician assistant with prescribing authority must issue a written order before crutches are dispensed. Post-supply orders do not satisfy this requirement.
• Appropriate crutch type: The order must specify non-wood underarm crutches (pair), not a generic crutch prescription. Specificity in the order language reduces audit exposure.
• MAC jurisdiction alignment: Some MAC jurisdictions have supplemental coverage policies that go beyond LCD L33733. Always verify your MAC’s local article before submitting E0114 claims.

ICD-10 diagnosis codes that support medical necessity

An E0114 claim must carry at least one ICD-10 diagnosis code that establishes medical necessity for ambulatory assistance. CMS reviews these codes against the approved list in LCD L33733 Article A52459. Using a code not on that list, even if it is clinically accurate, will result in a medical necessity denial. The list below reflects the most commonly accepted categories. Always verify the specific code version and coverage status against your MAC’s most recent article, as the approved code list can update with each ICD-10-CM annual revision.

Billers frequently encounter denials when using ICD-10 codes that are clinically appropriate but not on the LCD’s approved list. For example, low back pain code M54.5 (now split into M54.50, M54.51, M54.59 in recent ICD-10-CM editions) may appear on third-party code lookup sites as supporting E0114 but may not meet LCD criteria without a documented ambulation impairment finding. Always link the diagnosis to the functional limitation, not just the condition. Sports medicine practices managing post-fracture and post-surgical recovery see a large share of these claims, so this level of specificity matters most for them.

2026 Medicare fee schedule for HCPCS code E0114

E0114 is priced under the Medicare DMEPOS fee schedule, administered by the DME Medicare Administrative Contractors (DME MACs) rather than the physician fee schedule. The DMEPOS Competitive Bidding Program is currently in a gap period: every competitive bidding contract expired on January 1, 2024, and CMS does not expect the next round to start before 2028. During this gap, rates in former competitive bidding areas are the last single payment amount adjusted for CPI-U, while rates elsewhere follow the standard DMEPOS fee schedule methodology.

CMS publishes updated DMEPOS fee schedule files each calendar year. The 2026 allowable for E0114 should be verified directly against the CMS DMEPOS fee schedule lookup tool, since rates are subject to geographic adjustment and gap-period CPI-U updates. The same pricing methodology applies to other DME codes, such as A4358.

Applicable modifiers for E0114

Modifier selection is where E0114 claims fail most often in post-payment audits. CMS requires a DMEPOS modifier on every E0114 claim line. Crutches are Inexpensive or Routinely Purchased (IRP) DME, so the modifier only needs to indicate whether the equipment is new, rented, or used, not which month of a capped rental episode it belongs to. Omitting the modifier entirely causes an automatic claim rejection at the MAC level. Using the wrong modifier in the wrong context triggers a medical review or overpayment demand.

Crutches fall under Medicare’s Inexpensive or Routinely Purchased (IRP) DME category, not capped rental, so suppliers choose between purchase and rental rather than working through a multi-month rental sequence. For crutches, purchase with the NU modifier is the standard billing approach in most clinical settings. When rental does apply, the RR modifier is billed monthly until the cumulative rental payments equal the purchase price, at which point the supplier transfers ownership to the beneficiary.

Documentation requirements for billing E0114

Incomplete documentation is the single most audited risk area for DME claims. According to CMS and the OIG, documentation deficiencies account for a significant share of DMEPOS improper payments. For E0114, the required documentation checklist aligns with the Standard Written Order (SWO) standard, which replaced the Detailed Written Order (DWO) for claims with dates of service on or after January 1, 2020. This is guidance, not legal advice: always consult your MAC’s most current billing manual and any applicable LCD articles before finalizing your documentation policy.

Required documentation checklist

• Standard written order (SWO): Must specify the HCPCS code (E0114), the description of the item, the quantity, and the treating clinician’s signature and date. Generic crutch orders that do not specify non-wood or pair status are insufficient.
• Medical necessity documentation: The patient’s medical records must contain clinical findings that support the prescribed ambulatory aid. A diagnosis alone does not establish necessity; the record must connect the diagnosis to the functional limitation.
• Proof of delivery (POD): The beneficiary or their authorized representative must sign a delivery confirmation document that includes the HCPCS code, item description, and delivery date. The POD must be retained and available for audit.
• Beneficiary eligibility: Verify Medicare Part B enrollment and confirm the patient has not exceeded any applicable frequency limitations before dispensing. Crutches are generally not subject to capped rental for purchases but check current guidelines.
• Supplier enrollment: E0114 must be billed by a Medicare-enrolled DMEPOS supplier with the appropriate supplier standards accreditation. Billing under a physician’s NPI is not permitted for DME items in most circumstances.

Reducing audit risk

Maintaining digital forms for medical necessity documentation can reduce the risk of missing or illegible order information. Paper-based SWO workflows are a recurring audit finding in CMS DMEPOS audits because handwritten fields are often incomplete. Practices that handle HIPAA-compliant clinical documentation electronically report fewer pre-payment review delays.

The same documentation discipline applies across other DME codes, including B4157.

Related HCPCS crutch codes: how E0114 compares

Selecting the wrong code from the crutch family is a common billing error. Billers sometimes bill E0113 (a single wood crutch) when the patient actually received a non-wood pair, or reach for E0113 when E0116 (the non-wood each-code) is the correct match. Each code in the E0110-E0117 range has a specific material, configuration, and quantity requirement. The table below clarifies the distinctions.

The E0110–E0117 crutch codes

Choosing the right code

Medicare does not cover E0117. LCD L33733 states that the medical necessity of the articulating, spring-assisted crutch “has not been established,” so claims for E0117 are denied as not reasonable and necessary regardless of documentation. It isn’t a billable Medicare alternative to E0114.

E0113 and E0114 cover different products: E0113 is a single wood underarm crutch, while E0114 is a pair of non-wood underarm crutches. If a patient needs a single non-wood crutch rather than a pair, the matching each-code is E0116, not E0113. A biller who bills E0113 twice to represent a non-wood pair will trigger a duplicate-billing edit; the correct approach for a new non-wood pair is a single E0114 claim line with the NU modifier.

Common billing errors and denial reasons for E0114

No competing page in the current SERP covers the specific denial patterns for E0114 claims. This is the section that saves billers the most time, because each of these errors is avoidable with the right pre-submission workflow. The patterns below are drawn from standard CMS DMEPOS audit findings and common MAC denial categories for mobility aid codes.

Frequent errors that trigger denials

• Missing or incomplete physician order: The order does not specify E0114 or non-wood pair crutches. A generic “crutches” order is insufficient. The SWO must name the code or the item description in language that maps unambiguously to E0114.
• Wrong modifier applied: Billing NU (new) when the equipment was rented, or omitting the modifier entirely. Each claim line requires exactly one purchase or rental modifier. Claims without a modifier reject at the MAC clearinghouse before reaching a human reviewer.
• ICD-10 code not on the LCD-approved list: Using a diagnosis code that does not appear in LCD L33733 Article A52459’s supporting diagnoses. Even if the clinical condition genuinely impairs ambulation, an unapproved ICD-10 code generates a medical necessity denial.
• Billing E0113 twice instead of E0114 once: Submitting two E0113 (single crutch) lines to represent a pair is a duplicate-billing error. The correct claim is one E0114 line representing the pair.
• Missing proof of delivery: The beneficiary’s signature is missing from the POD, or the POD does not include the HCPCS code and item description. Suppliers without a complete POD on file cannot defend the claim in an audit.
• Supplier enrollment issues: The claim is submitted under a non-enrolled supplier NPI, or the supplier’s DMEPOS accreditation has lapsed. CMS rejects these claims before adjudication.

Preventing denials before submission

Practices that integrate their billing workflow with practice management software can build pre-submission checks for modifier presence, ICD-10 code validation, and documentation completeness. Catching these errors before claim submission reduces denial rates and eliminates the administrative cost of appeals. The same pre-submission discipline applies to other DME codes, such as B4105.

Conclusion

HCPCS code E0114 is a well-defined DME billing code, but the errors that lead to denials are consistent and preventable. The most common problems are modifier omissions, ICD-10 codes not on the LCD-approved list, and incomplete physician orders that do not specify the non-wood pair requirement.

Practice management software like Pabau gives practice billers and DME suppliers the tools to enforce documentation standards, validate modifiers, and organize delivery records before a claim ever reaches a biller or clearinghouse.
