HCPCS code L1652 – Hip orthosis

Key takeaways

HCPCS code L1652 describes a prefabricated bilateral hip orthosis with adjustable abductor spreader bar, adult size, fitting included.

L1652 is covered under the Medicare DMEPOS benefit and priced on the CMS DMEPOS fee schedule, which varies by locality.

The device billed under L1652 must appear on the PDAC verified product list before submitting any Medicare claim.

Pabau’s claims management software lets DME practices attach L-codes at the point of care and track claim status through to payment.

HCPCS code L1652: Full description and code details

HCPCS code L1652 covers a specific configuration of prefabricated hip orthosis. The CMS HCPCS Level II code set publishes the full official descriptor. It reads: Hip orthosis, bilateral thigh cuffs with adjustable abductor spreader bar, adult size, prefabricated, includes fitting and adjustment, any type. The short descriptor used on claim forms is: HO bi thighcuffs w sprdr bar.

Three descriptors within that definition carry billing weight. Bilateral means both thighs are cuffed, not just one. Adjustable abductor spreader bar refers to the connecting mechanism that controls hip abduction angle. Prefabricated means the device is manufactured to standard sizes rather than custom-fabricated from a patient impression. Fitting and adjustment are bundled into the code, so billing them separately results in a duplicate-service denial.

Medicare coverage and DMEPOS pricing for L1652

HCPCS code L1652 is covered under the Medicare Part B DMEPOS benefit when medical necessity is established and the product meets PDAC approval criteria. Medicare pays 80% of the fee schedule allowable after the deductible. The beneficiary or a secondary insurer covers the remaining 20%. Payment amounts are locality-adjusted using the CMS DMEPOS fee schedule files, which change each January 1 with the annual update.

Verify the allowable for your MAC jurisdiction before the device is ordered, not after it is delivered. A practice that quotes the national average rather than its own jurisdiction rate will misstate what the claim pays.

• Assigned billing: Medicare pays the supplier directly; the beneficiary pays the 20% coinsurance.
• Rental vs. purchase: L1652 is billed as a purchase, not capped rental.
• Competitive bidding: Check whether L1652 falls under a DMEPOS competitive bidding program contract in the beneficiary’s zip code. Contracted suppliers must be used when competitive bidding applies.
• Advance beneficiary notice (ABN): If medical necessity may not be met, obtain a signed ABN before delivering the device.

PDAC approval and medical necessity requirements for L1652

PDAC approval is a hard prerequisite for billing HCPCS code L1652 to Medicare. The Pricing, Data Analysis and Coding (PDAC) contractor reviews specific products submitted by manufacturers against the code descriptor. It then publishes a verified product list for orthotic HCPCS codes. A product that is not on this list is not billable under L1652, regardless of how closely it matches the physical description.

Confirm the manufacturer’s model number appears on the PDAC verified list before ordering the device for the patient. Confirming after delivery leaves you with a device you cannot bill. The check belongs inside the pre-authorization workflow, not in a pile of post-delivery paperwork.

• Verify the product model number against the PDAC approved product list before ordering.
• Retain the manufacturer’s PDAC confirmation letter or the PDAC product listing printout in the patient file.
• If the prescribing physician specifies a brand that is not PDAC-approved for L1652, contact the physician to discuss an approved alternative before proceeding.

Documentation requirements for billing L1652

A standard written order (SWO) is the central documentation requirement for HCPCS code L1652. It is not a certificate of medical necessity. CMS discontinued CMNs and DME information forms for all dates of service on or after January 1, 2023. DME MACs now reject claims that carry one.

CMNs never applied to orthoses in the first place. The form set only ever covered oxygen, pneumatic compression devices, osteogenesis stimulators, TENS units, seat lift mechanisms, external infusion pumps, and enteral or parenteral nutrition. An L-code claim was always evidenced by the order plus the treating practitioner’s clinical record.

The deadline for the SWO depends on which CMS list the code sits on. L1652 does not appear on the CMS face-to-face encounter and written order prior to delivery list. That list covers knee and ankle-foot orthoses, not hip codes. The SWO therefore has to be on file before the claim is submitted, not before the device is handed to the patient.

A complete L1652 documentation package includes the following. Use it as a pre-claim audit checklist. The diagnosis half of that package comes from the ICD-10-CM code set. Pull those codes from the practitioner’s notes, never from the claim form.

• Standard written order (SWO): Must carry the beneficiary’s name or Medicare Beneficiary Identifier, the order date, and a description of the item. It also needs the quantity dispensed, plus the treating practitioner’s name or NPI and signature.
• SWO received before billing: Because L1652 sits outside the written order prior to delivery list, you may deliver first. The signed SWO still has to reach your file before the claim goes out.
• Clinical notes supporting medical necessity: Practitioner or therapist notes describing the patient’s diagnosis and functional deficits. The notes must also say why a bilateral configuration with abductor bar is required rather than a simpler device.
• Qualifying ICD-10-CM diagnosis codes: The diagnosis codes on the claim must match the condition documented in the practitioner’s notes. Common examples include hip dysplasia, avascular necrosis, or post-surgical hip stabilization requirements.
• Proof of delivery: Signed delivery confirmation from the beneficiary or authorized representative, documenting the device serial number or model number.
• PDAC product confirmation: Documentation that the specific model billed is on the PDAC verified product list for L1652.

The claim form for a DMEPOS line carries the HCPCS code and the PDAC-approved product model. It also carries the ICD-10-CM codes, the place of service, and the rendering provider NPI. Missing any of those fields triggers an automatic edit that delays or denies payment.

L1652 vs L1686: Choosing the right HCPCS code

L1686 is the code most often confused with HCPCS code L1652. The distinction matters, because selecting the wrong one causes an outright denial rather than a correction request. L1652 covers a bilateral configuration, with an adjustable abductor spreader bar connecting two thigh cuffs. L1686 covers a unilateral postoperative hip abduction orthosis. It uses a waist band, one rigid upright with an adjustable hip joint, and a single thigh cuff, with no spreader bar. If the device cuffs both thighs and links them with a spreader bar, L1652 is the correct code. If it braces one hip after surgery, L1686 applies, and its custom-fabricated equivalent is L1685.

A device marketed as a “hip abduction orthosis” causes confusion regularly. It has bilateral pelvic and thigh components, but the spreader bar is fixed rather than adjustable. If the bar is not adjustable, it may not meet the L1652 descriptor precisely. Review the device’s product specification sheet alongside the PDAC verified product list entry to confirm which code the manufacturer obtained approval under.

Common billing errors when filing L1652 claims

Most L1652 denials cluster around five root causes. Fixing them upstream, before claim submission, removes the bulk of the rework. A documented pre-bill review against all five is the cheapest form of denial management available to an orthotic supplier.

• Product not on PDAC verified list: The device billed is not the one approved under L1652. Always verify model number, not just brand or product line.
• Wrong code selected (L1652 vs L1686): The device is unilateral, or lacks the adjustable abductor spreader bar, but L1652 is submitted anyway. Use the comparison table above to confirm laterality and spreader bar configuration before coding.
• Standard written order missing or incomplete: The SWO was never obtained, or it reached the file after the claim went out. It may also be missing the order date, the item description, or the practitioner’s signature. Submitting a discontinued CMN in its place gets the claim rejected outright.
• Diagnosis code mismatch: The ICD-10-CM codes on the claim do not match the diagnoses documented in the practitioner’s clinical notes. Coders pulling codes from the claim form without reviewing the clinical documentation create this mismatch routinely.
• Billing fitting separately: Fitting and adjustment are already included in the L1652 descriptor. A separate billing line for fitting services results in a duplicate-service denial.

The last error is not specific to L1652. HCPCS code L1660 also bundles fitting and adjustment into its descriptor, so a separate fitting line draws the same duplicate-service denial.

Related HCPCS L-codes for hip and lower extremity orthotics

HCPCS code L1652 sits within a family of L-codes covering hip orthoses and lower extremity devices. Two things separate them. One is laterality, and the other is whether the device is prefabricated or custom fabricated. Work down the descriptor before reaching for a code, because the product name rarely settles it. The branches below trace each descriptor to the code it points at.

Sizing separates the family further. L1652 is an adult-size code, so a flexible infant Frejka-type device for hip dysplasia is billed under L1600 instead. A Pavlik harness fitted for that same infant indication is billed under L1620.

How claims management software keeps L1652 claims clean

Billing HCPCS code L1652 requires coordinating at least six data points across the clinical and administrative workflow. Those are the standard written order, the supporting clinical notes, and the PDAC product confirmation. The remaining three are the ICD-10-CM diagnosis codes, the delivery confirmation, and the HCPCS code itself. In practices that use separate systems for clinical documentation and billing, one of those six handoffs becomes the failure point.

Practice management software like Pabau keeps all six on the same patient record. Pabau’s claims management software lets DME and orthotic practices attach L-codes to the patient encounter at the point of care. The biller sees the code, the associated diagnosis codes, and the documentation status without opening a second system.

Fewer handoffs means fewer transcription errors between the clinical record and the claim form. It also shortens the stretch between delivering the device and getting the claim out the door, which is where DMEPOS cash flow is usually lost.

Conclusion

L1652 is a descriptor-driven code, and its descriptor is narrow. It calls for two thigh cuffs, an adjustable abductor spreader bar, prefabrication, and an adult fit. A device that misses any one of those belongs under a different L-code, however the manufacturer markets it.

The practical consequence is that the coding decision happens before the order is placed. Check the PDAC verified list and read the specification sheet while the patient is still a candidate for the device. A supplier who leaves both until billing has already bought stock that may never be billable.

Pabau supports the DMEPOS documentation and coding workflow end to end, from code entry through claim submission and payment reconciliation. Book a demo to see how it handles orthotic and DME billing for your practice.
