HCPCS code T2035 – Utility services for medical equipment

Key takeaways

T2035 covers the added utility cost of running qualifying medical equipment or assistive technology at home, not general household bills.

Coverage, rates and the billing unit are set by each state’s Medicaid HCBS waiver, and no national Medicare fee schedule applies.

Missing prior authorization and thin medical necessity documentation are the two leading causes of T2035 denials.

T2034, T2036 and H2035 are the codes most often confused with T2035, and none of them covers utility support.

HCPCS code T2035: official descriptor and code details

HCPCS code T2035 is the code for utility services that keep medical equipment and assistive technology running in a Medicaid waiver beneficiary’s home. It belongs to the T-series of HCPCS Level II codes, which the Centers for Medicare and Medicaid Services (CMS) maintains for state Medicaid agencies. The official descriptor reads “Utility services to support medical equipment and assistive technology/devices, waiver.” The code is active for the 2026 billing year.

T-series codes give states a way to bill Medicaid home and community-based services (HCBS) waiver services that fall outside Medicare’s benefit categories. T2035 sits among neighboring codes for very different waiver services. Knowing those neighbors is the fastest way to catch a wrong-code claim before it goes out.

What T2035 covers and what it excludes

T2035 covers only the portion of a utility bill that comes from powering qualifying durable medical equipment (DME) or assistive technology (AT). The key word is “incremental,” meaning only the cost above what the household would pay without the equipment running.

Covered under T2035

• Additional electricity costs from operating a ventilator, suction machine, infusion pump, or power wheelchair charger
• Gas or water costs when the qualifying medical equipment needs those utilities to function
• Incremental utility expenses documented through a utility bill comparison or the manufacturer’s published power consumption data
• Costs tied to assistive technology devices that meet the state’s waiver definition of AT

Excluded from T2035

• General household utility bills not attributable to qualifying equipment
• Utility costs for equipment covered under a separate Medicare DME benefit
• Equipment that does not meet the payer’s DME or AT criteria under the applicable waiver
• Costs already reimbursed through another Medicaid benefit or service category

The exclusion of Medicare-covered equipment is a frequent audit trigger. If a beneficiary’s ventilator is billed under a Medicare DME claim, the associated utility costs cannot also be billed under T2035 through Medicaid. State Medicaid integrity contractors look for that kind of double billing.

Put together, coverage comes down to four checks, and a claim that fails one of them stops there.

Which payers accept T2035 and Medicaid billing requirements

T2035 is not a Medicare benefit. It is a Medicaid HCBS waiver code, so payment depends on two conditions. The beneficiary’s state must include this service in its approved waiver, and the beneficiary must be enrolled in that waiver. Medical billing workflows for Medicaid differ from Medicare billing. States have their own fee schedules, eligibility rules, and coverage scopes.

According to the CMS HCPCS Level II code set, T-series codes are national codes that states adopt at their discretion. Whether a given state covers T2035 depends on that state’s waiver authority under 42 CFR Part 441 Subpart G.

2026 fee schedule and T2035 reimbursement rates

There is no national Medicare fee schedule for HCPCS code T2035. Each state Medicaid agency sets the rate and publishes it in that state’s Medicaid fee schedule. Rates vary widely. Some states set a flat monthly allowance, and others reimburse documented incremental costs up to a defined cap.

The CMS Physician Fee Schedule lookup does not include T2035 because this code is not a Medicare benefit. To find the applicable rate and billing unit, billing staff need to check their state Medicaid agency’s published fee schedule directly.

T2035 documentation requirements for Medicaid billing

Incomplete documentation is the second leading cause of T2035 denials, after missing prior authorization. The file has to show that the qualifying equipment exists and that the beneficiary is enrolled in the applicable waiver. It also has to show the utility cost is incremental to running that equipment.

• Physician order or plan of care. It must name the specific qualifying equipment generating the utility cost and the medical necessity for that equipment.
• Waiver enrollment confirmation. Keep proof that the beneficiary is currently enrolled in the HCBS waiver program that covers T2035.
• Utility bill documentation. Keep copies of the utility bills, with a calculation showing the incremental cost of the qualifying equipment.
• Equipment documentation. An invoice, DME certificate of medical necessity, or manufacturer’s power consumption data supports the utility cost calculation.
• Prior authorization approval. File the PA approval letter from the state Medicaid agency or managed care organization, where one is required.
• Date range covered. Records must match the billing period. Many states bill T2035 monthly, so confirm the unit in your state manual.

Auditors look for internal consistency. If the plan of care names a ventilator and the utility calculation references a suction machine, that mismatch is enough to trigger a payback demand. Every document in the file should reference the same piece of equipment.

Medical billing compliance for Medicaid waiver services means keeping this documentation in the patient record for the state’s audit period, typically five to seven years.

How to bill T2035: claim submission steps

Billing HCPCS code T2035 on an 837P or CMS-1500 form means filling several fields that differ from standard Medicare claims. Good claims management software cuts the manual entry and helps catch field-level errors before submission.

1. Verify waiver enrollment. Confirm the beneficiary is active in the applicable HCBS waiver before preparing the claim. A lapsed enrollment date is an automatic denial.
2. Confirm prior authorization status. Get the PA number if the payer requires it. Enter it in Box 23 on the CMS-1500 or in the prior authorization reference field on the 837P.
3. Enter T2035 in the procedure code field. That is Box 24D on the CMS-1500. No CPT code replaces it, and T2035 stands alone.
4. Apply the correct modifier. Modifiers vary by state, and many identify the waiver type. Check the payer’s billing manual before adding any modifier.
5. Set the place of service. This is typically Place of Service 12 (Home), since utility support applies to equipment running in the home.
6. Bill the unit your state sets. Many states bill one unit per month, but the descriptor itself names no unit. Confirm the unit in the state manual, because billing more units than it allows is an overbilling error.
7. Attach supporting documentation. Some state Medicaid agencies and MCOs require the utility cost calculation as a claim attachment. Check payer requirements.

A well-structured superbill captures the waiver program identifier, the PA number, and the equipment reference. That makes the 837P or CMS-1500 faster to fill and less error-prone.

T2035 vs neighboring codes: T2034, T2036 and H2035

The T2030-T2040 block covers a range of HCBS waiver services that are easy to conflate. Picking the wrong code gets the claim denied or overpaid even when the underlying service is legitimate.

Coders sometimes expect T2034 to be a transport code, but non-emergency transport sits earlier in the series, at codes such as T2003.

H2035 deserves special attention because it differs from T2035 by a single character. H-series codes cover behavioral health and substance use services and have no link to T-series waiver codes. Submitting H2035 on a utility services claim will draw an immediate categorical mismatch denial.

Common T2035 claim denial reasons and how to prevent them

Most T2035 denials trace back to one of six root causes. Treat Medicaid waiver denials as their own track in your denial management workflow, because their causes differ from standard fee-for-service denials. The two biggest, missing prior authorization and lapsed waiver enrollment, can both be caught before the claim goes out.

The AAPC’s HCPCS Level II code reference and the PGM Billing HCPCS lookup tool help you cross-check the current descriptor and payer edits. Use them before you resubmit a denied T2035 claim.

How Pabau helps billing teams submit and track T2035 claims

Without a shared system, a T2035 claim is pieced together by hand. The plan of care lives in one place, the utility calculation in a spreadsheet, and the claim in a payer portal. Each handoff is a chance for details to be retyped wrong.

Pabau, the practice management platform we build, keeps patient records, forms and billing in one system. Its claims management tools pull the data already on the patient record into the claim, then submit it and track its status. Your team stops copying the same details between systems.

Your billers still confirm waiver enrollment, prior authorization and the state’s billing unit. With the claim built from the record, their time goes into those checks instead of data entry.

Conclusion

HCPCS code T2035 is a narrow Medicaid waiver benefit that pays for the added cost of keeping essential medical equipment running at home. Many billing teams overlook it. The code is simple to report, but it punishes incomplete documentation and skipped prior authorization with consistent denials.

Before the first claim, read your state’s waiver manual and fee schedule once. Confirm that the waiver covers T2035, which billing unit it uses, and whether prior authorization applies. Get those three answers on file and each later claim becomes routine.
