HCPCS Code A4245: Alcohol wipes, per box

Key Takeaways

HCPCS Code A4245 describes “Alcohol Wipes, Per Box” and falls under the A4244-A4297 category covering other supplies including diabetes supplies and contraceptives.

Bill A4245 at one unit per box supplied: four boxes = A4245 x 4. Billing by the box is the standard unit of measure for this code.

Medicare Part B excludes A4245 as a stand-alone blood glucose monitor supply under CMS Policy Article A52464, regardless of documentation. Coverage is more realistic under ESRD composite billing, state Medicaid, or commercial payer policies.

Pabau, practice management software with built-in claims management, helps DMEPOS suppliers and clinic billing teams track HCPCS supply codes, attach diagnosis codes, and reduce A4245 claim denials.

The Centers for Medicare and Medicaid Services (CMS) defines HCPCS Code A4245 as “Alcohol Wipes, Per Box.” Specifically, the code sits in the HCPCS Level II A-code range. It falls under the A4244-A4297 category: Other Supplies Including Diabetes Supplies and Contraceptives.

CMS maintains it in the HCPCS Level II code set and updates it annually. Billers sometimes search for the “A4245 CPT code description.” However, A4245 is a HCPCS Level II code, not a CPT code. So the alcohol wipes HCPCS code description is simply “Alcohol wipes, per box.”

Alcohol wipes coded under A4245 are pre-moistened towelettes containing 70% isopropyl alcohol. Their clinical purpose is to disinfect the skin surface before injections, blood glucose testing, or minor procedures. In the diabetes supply context, they’re routinely dispensed alongside lancets, test strips, and glucose monitors.

For DMEPOS suppliers, A4245 is a high-volume, low-cost supply code where billing accuracy matters more than reimbursement size. That makes it a good fit for claims management software that flags errors before submission rather than after a denial.

Billing units and how to submit HCPCS Code A4245

The most common A4245 billing error is a unit count mistake. A4245 billing units are counted per box, not per individual wipe, so one box supplied equals one unit billed.

For four boxes of alcohol wipes, the correct submission is A4245 x 4. Billers used to per-item or per-100-count coding sometimes submit A4245 x 1 regardless of quantity dispensed, leaving reimbursement on the table. Others submit a unit count matching the wipe count inside the box, which triggers a system-level edit.

Unit examples

DMEPOS suppliers billing A4245 often manage other per-unit supply codes in the same order. For example, they may bill A4930 for sterile gloves or A7032 for CPAP nasal mask cushions. Keeping clinic inventory management synced with what’s actually been dispensed keeps unit counts accurate across every code, not just A4245.

Virginia DMAS confirmed effective July 1, 2014 that providers may ship a 90-day supply for A4245 alongside a defined list of other diabetic supplies. New York eMedNY permits pharmacy billing of A4245 as a medical supply under its March 2023 updated provider manual. Always confirm the 90-day supply rules with the specific state Medicaid program before dispensing.

Good medical forms at your practice help capture the dispensed quantity at the point of supply, reducing unit errors at claim submission. When staff document the dispensed quantity in the patient record at the point of supply, the billing team gains a verifiable source of truth. As a result, they no longer rely on memory or batch notes.

Medicare coverage for HCPCS Code A4245

Medicare Part B does not cover A4245 when it’s billed as a stand-alone supply for a home blood glucose monitor. CMS Policy Article A52464 classifies A4245, along with A4244, A4246, and A4247, as non-covered because these antiseptic supplies are “not required for the proper functioning of the device.” That’s a blanket exclusion, and it applies regardless of how complete the supporting documentation is.

This BGM-supply exclusion is separate from the CGM-replacement exclusion described below under LCD L33822. The two policies deny A4245 for different reasons, so suppliers should track them separately rather than treating denials from one as evidence about the other.

A4245 coverage matters most in the ESRD/dialysis context, where it can fall under the composite rate. State Medicaid and commercial payer policies may also cover it under their own rules. Where a payer does reimburse A4245, the payment is carrier-priced. In other words, the local DME MAC or the specific payer sets the fee rather than a national fee schedule, so A4245 reimbursement varies by jurisdiction.

CGM policy impact on A4245 coverage

A significant change affects suppliers billing A4245 for patients who use non-adjunctive continuous glucose monitors (CGMs). Under CMS Local Coverage Determination LCD L33822 (Glucose Monitors), non-adjunctive CGM devices replace standard home BGMs and their related supplies. The CMS coverage database lists A4245 explicitly as one of the supply codes replaced when a patient transitions to a non-adjunctive CGM. In practice, once a supplier bills a covered CGM device such as E2100 or E2101, payers will likely deny A4245 for the same coverage period.

Noridian Healthcare Solutions, as a DME MAC for Jurisdiction D, confirms this replacement policy on its glucose monitors guidance page. DMEPOS suppliers should update their billing workflows to flag CGM-enrolled patients and suppress A4245 claims accordingly, or prepare a medical necessity rationale if both supplies are genuinely required.

ESRD supply context

A4245 also appears in ESRD supply billing for patients on home dialysis. Alcohol wipes are a standard part of dialysis supply kits for skin preparation before needle insertion. A consolidated billing arrangement handles coverage for ESRD patients. Therefore, suppliers should verify whether the ESRD composite rate bundles A4245 for their specific payer before billing separately.

Suppliers billing A4245 in this context often also bill the dialysis session itself under 90935, or ESRD-related biosimilar drug codes such as Q5105, in the same claims cycle.

Tracking payer-specific coverage variations requires organized patient records. HIPAA compliance documentation across payer types helps practices maintain the audit trail payers require when coverage criteria are contested.

Documentation requirements for A4245 claims

Inadequate documentation is the second-most common reason for A4245 denials after coverage exclusions. Payers generally require the following to support an A4245 claim:

• Written order: A physician or treating provider order specifying the supply item, quantity, and frequency. For Medicare, this must predate the date of service.
• Diagnosis code linkage: An active ICD-10-CM diagnosis code supporting medical necessity. For diabetes supplies, E11.x (Type 2 diabetes mellitus) or E10.x (Type 1 diabetes mellitus) with the appropriate complication suffix is the standard.
• Proof of delivery: A signed delivery confirmation or patient acknowledgment showing the patient received the supplies. For mail-order DMEPOS, a shipping confirmation with tracking may satisfy this requirement depending on the payer.
• Patient eligibility verification: Confirmation the beneficiary is enrolled in Part B and meets the coverage criteria at the time of supply.
• Refill documentation: For recurring supply orders, documentation that the patient is still using and needs the supplies, typically a signed refill request or contact log.

Suppliers building their own authorization paperwork can start from a general HIPAA authorization form template and adapt it to DMEPOS-specific proof-of-delivery language.

Using digital forms to capture refill confirmations and patient acknowledgments creates a timestamped, searchable record that satisfies most payer audit requests without staff scrambling through paper files.

ICD-10 diagnosis codes that support A4245 medical necessity

Always verify that the diagnosis code on the claim exactly matches the diagnosis in the treating provider’s order. A mismatch between the order’s diagnosis and the claim diagnosis is a frequent audit finding. Moreover, it can trigger a retroactive recoupment demand even after initial payment.

HCPCS Code A4245 vs. related codes: A4244, A4246, A4247

A4245 sits within a tight cluster of antiseptic and wound care supply codes. Selecting the wrong code from this group is a common coder mistake. That’s because the supplies look similar but differ in form, concentration, and clinical application. Use the AAPC Codify HCPCS lookup to verify the current descriptor and code properties for any code in this range before submitting.

The most frequent confusion is between A4245 and A4247. Both are pre-moistened wipes billed per box, but A4245 is alcohol-based and A4247 is iodine/betadine-based. If a patient is allergic to iodine and uses alcohol wipes exclusively, A4247 is the wrong code regardless of how similar the products appear in an order entry screen. Documenting the specific product dispensed in the patient record prevents this error.

Robust patient management software links supply orders to specific product SKUs. As a result, teams can confirm the correct HCPCS code at the point of order rather than during a post-submission audit.

DMEPOS supplier requirements and payer-specific coverage

To bill A4245 to Medicare, a supplier must be an enrolled DMEPOS supplier with an active National Provider Identifier (NPI), an active surety bond, and accreditation from a CMS-approved accreditation organization. Suppliers that are not enrolled cannot bill A4245 or any HCPCS supply code directly to Medicare, regardless of whether the patient qualifies for coverage.

Medicare vs. Medicaid vs. commercial payer variations

• Medicare Part B: Does not cover A4245 as a stand-alone BGM supply under Policy Article A52464, and CGM-enrolled patients face a separate exclusion under LCD L33822. Coverage is most realistic in the ESRD/dialysis composite rate context. Claims go to the applicable DME MAC: Noridian (Jurisdictions A and D) or CGS Administrators (Jurisdictions B and C), depending on supplier location.
• Medicaid (state-specific): Virginia DMAS allows a 90-day supply. New York eMedNY allows pharmacy billing of A4245 as a medical supply. Coverage criteria and reimbursement rates vary significantly by state. Always consult the applicable state Medicaid provider manual before billing.
• Commercial payers: BCBS Florida reviewed its coverage policy for A4245 (MCG policy 09-E0000-14, reviewed August 2025) and deleted a previous non-covered designation for the code, indicating the code moved from non-covered to potentially covered status. Always verify current coverage with the specific commercial plan, as policies change.

Use the PGM HCPCS lookup tool to cross-reference A4245 descriptions and confirm there are no mid-year code changes that affect your claims. Staying current with annual CMS HCPCS updates is a basic supplier compliance obligation.

DMEPOS suppliers rarely bill A4245 in isolation. The same claims cycle often includes higher-value drug codes like Q5104, which makes clean revenue cycle management across every code on the claim just as important as getting A4245 right.

Electronic transactions involving A4245 claims, including electronic remittance advice (ERA) and electronic funds transfer (EFT), must meet the safeguards required of HIPAA-compliant systems. Suppliers handling patient health information in their billing workflows need to maintain these safeguards regardless of the code value involved.

Common A4245 claim denial reasons and how to address them

Three denial patterns account for the majority of A4245 rejections at most DMEPOS suppliers:

Non-covered supply due to CGM enrollment

As noted under the Medicare coverage section, patients enrolled in a non-adjunctive CGM program are no longer eligible for separate reimbursement of A4245. The denial reason code will typically reference a coverage limitation or indicate the supply is included in a comprehensive billing arrangement. The resolution is to verify CGM enrollment status before submitting and remove A4245 from the claim if CGM billing applies. There is no appeal pathway that overrides LCD L33822 for this exclusion unless the clinical scenario genuinely falls outside the CGM replacement policy’s scope.

Missing or invalid diagnosis code

A4245 claims denied for invalid or missing diagnosis codes usually have one of three causes: the ICD-10-CM code is listed in the wrong position on the claim form, the code is unspecified when a more specific code is available and required by the payer, or the code does not match the code listed in the treating provider’s written order. Correct by reviewing the order, updating the diagnosis to match, and resubmitting with the corrected ICD-10-CM code. Confirm with the payer whether a corrected claim or a reopening request is the appropriate pathway.

Unit count errors

Billing A4245 with a unit count that exceeds the quantity authorized in the written order, or the payer’s Medically Unlikely Edit (MUE) limit, will trigger a denial or partial payment. If the supplier dispensed more boxes than the order authorized, obtain a retroactive order amendment from the treating provider before appealing. Going forward, automate the unit-to-order quantity check in your billing workflow so excess units flag before submission rather than after denial.

Structured billing workflows inside practice management software can link dispensed quantity records directly to the order quantity, flagging mismatches before the claim leaves the system. That kind of automated check catches unit errors on high-volume supply codes like A4245 without relying on manual review of every line item.

Conclusion

HCPCS Code A4245 is a straightforward supply code with several non-obvious coverage traps:

• The blanket BGM-supply exclusion under CMS Policy Article A52464
• The separate CGM-replacement exclusion under LCD L33822
• State Medicaid supply quantity rules
• The easy-to-confuse A4244/A4246/A4247 neighbor codes

Getting the unit count right and pairing the claim with the correct ICD-10-CM diagnosis are the two most impactful steps any billing team can take to reduce denials on this code.
