HCPCS code E0255 – Variable-height hi-lo hospital bed

Key takeaways

HCPCS Code E0255 covers a variable-height (hi-lo) hospital bed with manual height adjustment, any type of side rails and a mattress.

A bed with electric head and foot adjustment is billed as E0260 (semi-electric) or E0265 (total electric), not as E0255.

Medicare covers E0255 under LCD L33820 when the patient meets a fixed-height bed criterion and needs a different bed height for transfers.

E0255 is a 13-month capped rental, billed with RR plus KH, KI or KJ at 10% and then 7.5% of the purchase price.

Modifier KX goes on the claim only when every L33820 criterion is met and documented in the medical record.

What is HCPCS Code E0255?

HCPCS Code E0255 is the durable medical equipment (DME) code for a hospital bed, variable height (hi-lo), with any type of side rails, with mattress. The Centers for Medicare and Medicaid Services (CMS) publishes it in the HCPCS Level II code set. Suppliers use it to bill Medicare Part B and commercial payers for a home-use variable-height bed.

The “hi-lo” designation means the bed frame is raised and lowered manually. A caregiver can then work at a comfortable height, and the patient can transfer safely. The head and foot sections also adjust manually. Electric adjustment moves the bed to E0260 or E0265.

The code bundles the bed frame, any type of side rails (half or full-length) and a standard mattress into one line item.

The table below shows which components E0255 bundles and which ones a supplier bills under a separate code.

Once the bed is delivered, the supplier bills Medicare monthly and collects the patient’s 20% coinsurance separately.

E0255 vs. neighboring hospital bed codes

The most common miscoding errors on E0255 involve confusing it with E0250 or E0260. All three codes cover hospital beds for home use, but their physical features differ enough to make each code distinct under Medicare’s criteria. Selecting the wrong code is one of the top audit triggers for DME suppliers.

Key differentiator: On an E0255 bed, every adjustment is manual: overall height, head and foot. E0260 makes the head and foot adjustment electric, while its height still adjusts manually. If the delivered bed adjusts the head and foot sections electrically, E0260 applies, not E0255. Billing E0255 for a semi-electric bed is a coding error that can trigger a claim audit.

Medicare coverage criteria for HCPCS E0255

Medicare Part B covers HCPCS E0255 as DME for home use when the patient meets the criteria in a Local Coverage Determination (LCD). The governing LCD is L33820 (Hospital Beds and Accessories), issued by the DME MACs (Noridian and CGS). Check the current version of L33820 before each order, because LCD criteria are revised periodically.

A variable-height bed is covered when the patient meets at least one fixed-height hospital bed criterion. The patient must also need a bed height different from a fixed-height bed, to permit transfers to a chair, wheelchair or standing position. The fixed-height criteria are:

• The patient’s condition requires body positioning not feasible with an ordinary bed. The condition is expected to last at least one month.
• The patient requires positioning of the body in ways not feasible with an ordinary bed to alleviate pain.
• The patient requires the head of the bed elevated more than 30 degrees most of the time. The cause is congestive heart failure, chronic pulmonary disease or aspiration problems. Pillows or wedges must have been considered and ruled out.
• The patient requires traction equipment that can only be attached to a hospital bed.

The ordering physician must document both parts explicitly, because a diagnosis alone is not sufficient. The record has to name the fixed-height criterion the patient meets and explain why transfers need a different bed height. Good medical billing compliance includes a documentation checklist in the order workflow, completed before the bed is delivered.

Medical necessity documentation requirements for E0255

Documentation for HCPCS Code E0255 must be assembled before billing, not after. The DME MAC can request records at any point, and a record missing at delivery cannot always be corrected later. Required documentation typically includes the following:

• Physician order or prescription: A written order from the treating physician. It identifies the equipment by name or HCPCS code and states the length of need.
• Detailed Written Order (DWO): A more comprehensive order that includes the beneficiary’s name, item ordered, date of the order, and physician signature. Required before delivery for most DME items under Medicare.
• Supporting medical records: Office visit notes or other records that document the diagnosis, the functional limitations, and why a variable-height bed is medically necessary. Records must be dated before or at the time of the order.
• Certificate of Medical Necessity (CMN): Not required for hospital beds. Form CMS-849, sometimes cited for beds, is the CMN for seat lift mechanisms.
• ICD-10-CM diagnosis codes: Must appear on the claim and must match the diagnosis documented in the medical record. Codes must support the medical necessity criteria in the applicable LCD.
• Length-of-need justification: Documentation of how long the bed is expected to be needed. It sets the rental duration and the capped rental billing timeline.

Medicare requires DME suppliers to retain documentation for seven years from the date of service. A superbill that captures the diagnosis and procedure codes at the point of service starts the documentation trail before a claim is filed.

How to bill HCPCS Code E0255: Rental vs. purchase

HCPCS Code E0255 is billed under Medicare’s capped rental model, the standard payment method for most hospital beds classified as DME. Knowing how medical billing works for capped rental items prevents a common error: billing rent past the ownership transfer point.

The capped rental billing sequence for E0255 works as follows:

1. Months 1 through 3: Bill monthly with modifier RR (rental), plus KH in month 1 and KI in months 2 and 3. The allowed amount is 10% of the purchase price each month.
2. Months 4 through 13: Continue billing monthly with RR plus KJ. The allowed amount drops to 7.5% of the purchase price each month.
3. Month 13 (the cap): This is the final rental billing month. After the 13th rental month, ownership of the equipment transfers to the Medicare beneficiary. No further rental charges may be billed.
4. Post-month 13: The supplier must still service the equipment at no extra charge for 6 months after ownership transfers. After that, separately billed servicing (modifier MS) may apply.
5. Partial-month rentals: When equipment is delivered or returned mid-month, use modifier KR to indicate a partial-month rental. The allowed amount is prorated.

In each month, Medicare pays 80% of the allowed amount and the beneficiary owes 20% coinsurance. Across all 13 months, the allowed amounts add up to 105% of the purchase price, as the timeline below shows.

Purchase billing (modifier NU for new equipment, UE for used equipment) applies only in limited circumstances. One example is a commercial payer whose policy covers purchase rather than rental. Verify the payer’s policy before switching from rental to purchase billing.

HCPCS E0255 modifiers: When and how to use them

Correct modifier selection is where most E0255 billing errors occur. The modifiers below cover different billing scenarios, and an invalid combination leads to automatic claim rejection. Always verify modifier stacking rules against AAPC’s HCPCS code guidance and your specific DME MAC’s billing guidelines before submitting.

Common stacking error: Billing RR and NU on the same claim line is invalid, because a claim cannot be both a rental and a purchase. KX and GY cannot appear together either. KX asserts the criteria are met, while GY asserts the item is not covered.

Medicare fee schedule and reimbursement rates for E0255

Medicare reimbursement for HCPCS Code E0255 is set by the DMEPOS fee schedule, which CMS updates annually. Rates vary by jurisdiction and by whether the supplier operates in a Competitive Bidding Area (CBA). Suppliers in CBAs are paid the competitive bidding rate, which is typically lower than the national fee schedule rate. Suppliers outside CBAs are paid the national rate.

Rates change each January 1 and CBA status changes periodically, so dollar amounts in third-party sources go stale quickly. Use the CMS DMEPOS fee schedule files to find the current allowed amount for E0255 in your state. Tracking reimbursement inside a broader revenue cycle management workflow helps suppliers catch rate changes before they affect cash flow.

Medicare pays 80% of the allowed amount after the beneficiary deductible is met. The remaining 20% is the beneficiary’s coinsurance responsibility, which may be covered by a supplemental (Medigap) policy. Verify secondary coverage before delivery to set accurate billing expectations.

Prior authorization requirements for HCPCS E0255

Medicare does not currently require prior authorization (PA) for E0255. The code is not on CMS’s Required Prior Authorization List for DMEPOS items. CMS adds codes to that list through Federal Register notices, so check the current list before each order.

If CMS ever adds E0255 to the list, the Medicare PA process works as follows:

• The DMEPOS supplier submits a prior authorization request to the DME MAC before delivering the equipment.
• The request includes the same documentation required for billing: the physician order, the DWO, the supporting medical records and the ICD-10 diagnosis codes.
• The DME MAC issues a provisional affirmation or a non-affirmation. A provisional affirmation does not guarantee payment, but it makes a post-payment denial on the same documentation much less likely.
• After a non-affirmation, the supplier can correct the documentation and resubmit the request.

Commercial payers set their own prior authorization rules, separate from Medicare’s. Check each payer’s policy for E0255 before delivery, because a missing commercial PA is a non-correctable denial in most cases. Strong denial management flags PA requirements at order entry, before the delivery window opens.

Common claim denial reasons for E0255 and how to avoid them

E0255 claims are denied for predictable reasons. Most denials trace back to documentation assembled after delivery, or to modifier errors that claim scrubbing could have caught. Knowing the common denial codes helps billers find the root cause faster and prioritize appeals.

ICD-10 diagnosis codes commonly paired with HCPCS Code E0255

The ICD-10-CM codes on an E0255 claim must support the LCD criteria, not simply reflect the patient’s primary diagnosis. A diagnosis code alone is not sufficient, so the record must also show the functional impairment that requires a variable-height bed. Verify that each code in the table below is current before use, because ICD-10 updates take effect each October 1.

Use the PGM Billing HCPCS lookup tool or the AAPC Codify HCPCS lookup to cross-reference codes and verify active status.

Pairing a high-specificity ICD-10 code with a narrative note on the functional limitation strengthens the medical necessity case. Avoid “unspecified” codes where a more specific code exists, because specificity signals thorough documentation to the DME MAC reviewer. A clean claim with matched diagnosis codes and complete records reduces the chance of a prepayment review.

How Pabau supports E0255 documentation and claim tracking

An E0255 claim stands or falls on the ordering practice’s notes. The supplier bills the bed, but the record has to show the L33820 criterion the patient meets and why a fixed-height bed blocks safe transfers.

In Pabau, that reasoning sits in the treatment note next to the diagnosis and the signed order. When a supplier or MAC requests records, the practice pulls them from one patient record instead of chasing paper files.

Pabau’s claims tracking software then submits claims and tracks their status. A rejected claim shows up quickly, while the visit and its documentation are still fresh.

Keep bed orders documented and claims tracked

Pabau keeps the notes behind each hospital bed order in one patient record, then submits and tracks your claims. Records are ready when a supplier or MAC asks.

Conclusion

The decision that protects an E0255 claim happens before the bed leaves the warehouse. Confirm that the patient meets a fixed-height criterion and needs a different bed height for transfers, and get both into the record. Then confirm the delivered bed is fully manual, because electric head and foot adjustment makes it E0260 or E0265.

That intake check slows the order by a day or two. Skipping it puts up to 13 months of rental claims at risk. Book a demo to see how Pabau keeps the ordering practice’s notes and claim status in one place.
