HCPCS code V5243 – Monaural analog ITC hearing aid

Key takeaways

HCPCS code V5243 covers one conventional analog hearing aid worn in the ear canal (ITC) and fitted to a single ear.

V5243 is not digitally programmable. An ITC aid set up with fitting software bills as V5245, and a fully digital ITC aid bills as V5255.

V5243 is billed per ear with the RT or LT modifier. Analog ITC aids in both ears bill as V5249 instead.

Medicare Part B excludes hearing aids under Section 1862(a)(7) of the Social Security Act, so payment comes from Medicaid, Medicare Advantage or commercial plans.

Pabau, the practice management platform we build, keeps the audiogram, device specification and PA number on one patient record. Each V5243 claim then goes out complete.

HCPCS code V5243: Official descriptor and code family

HCPCS code V5243 is the Level II code for a single conventional analog hearing aid worn in the ear canal (ITC). It sits in the V5120-V5267 hearing aid range maintained by the Centers for Medicare and Medicaid Services (CMS). The official descriptor is Hearing aid, analog, monaural, ITC (in the canal).

Each part of that descriptor narrows the code. Analog means conventional analog circuitry with no digital programming, so the aid is adjusted by hand rather than by computer. Monaural means one aid for one ear. ITC means a custom shell that sits in the outer part of the ear canal, smaller than an in-the-ear aid.

The table below lists the attributes billers need to confirm before submitting a claim.

What V5243 covers and what it excludes

V5243 applies when an audiologist or hearing instrument specialist dispenses one analog ITC aid to one ear. Three facts must all be true: one ear, an ITC shell and conventional analog technology. If any of them changes, the code changes too.

Clinical situations that typically support a monaural V5243 fitting include:

• Unilateral hearing loss that meets the payer’s audiometric criteria, with normal or near-normal hearing in the other ear
• Asymmetric loss where only one ear is aidable, or where the audiologist documents why a second aid would not help
• Replacement of one lost or damaged analog ITC aid from a pair, when the other aid is still working
• A long-term analog ITC wearer who asks for a like-for-like replacement rather than a programmable or digital aid

These scenarios fall outside V5243 and need a different code:

• Both ears fitted with analog ITC aids: A binaural analog ITC fitting bills as V5249, not two lines of V5243.
• Digitally programmable aids: An ITC aid adjusted with fitting software bills as V5245 for one ear or V5251 for both ears.
• Fully digital aids: A monaural digital ITC aid bills as V5255, and a binaural digital ITC pair bills as V5259.
• Other analog styles: A monaural analog CIC aid bills as V5242. Conventional monaural in-the-ear and behind-the-ear aids use V5050 and V5060.
• Programmable behind-the-ear aids: V5247 covers one digitally programmable analog BTE aid, a different device in both style and technology.
• Dispensing fees: The fitting service bills separately, usually as V5241 for a monaural hearing aid of any type.
• Ear impressions, batteries and supplies: The impression for the custom shell (V5275), batteries (V5266) and other supplies (V5267) are never bundled into V5243.

V5243 vs V5245, V5249 and neighboring hearing aid codes

Most V5243 errors come from picking a code one attribute away. Billers swap in the programmable code, the binaural code or a different style. The table below maps the neighbors that coders most often confuse with V5243.

Ask how the aid was set up before you count the ears. If the audiologist programmed it with fitting software, it is not V5243, whatever the shell style. Fully digital aids dominate the market today, so a new ITC aid is far more likely to be V5255. The grid below sets the six ITC codes side by side.

Confirm the circuitry on the manufacturer’s specification sheet and keep it with the fitting record. The AAPC hearing aid code range lists every descriptor in the family.

Payer coverage for V5243

Whether V5243 gets paid depends on the payer type, so verify current plan benefits before dispensing.

Payers price V5243, V5245 and V5255 as separate fee schedule lines. A wrong technology code can therefore change the allowance, even when the claim is not denied outright.

Prior authorization requirements for V5243

Many state Medicaid programs and commercial plans require prior authorization (PA) before paying a V5243 claim. A missing PA number is one of the most preventable denials in hearing aid billing. Confirm insurance eligibility and PA status before you book the fitting appointment.

Typical PA criteria include:

• A current audiogram showing qualifying loss in the ear being fitted
• A physician referral or audiologist order for a hearing aid evaluation
• A medical necessity statement that explains why one ear is being fitted
• The manufacturer, model, style and technology type of the device, with the ear noted
• Trial-period or loaner documentation where the payer requires it

Documentation requirements for V5243 claims

Every V5243 claim needs a contemporaneous record that proves medical necessity and confirms the aid was dispensed. Work through this checklist at the fitting appointment, while the patient is still in the office.

• Audiogram: Pure-tone and speech results within the payer’s lookback window, signed by the performing audiologist.
• Order: A written referral or prescription for the hearing aid evaluation and fitting.
• Medical necessity statement: The audiometric findings for the fitted ear, and why a monaural fitting is appropriate.
• Device details: Manufacturer, model, serial number and a specification sheet confirming analog ITC circuitry with no digital programming.
• Ear impression: The date the impression for the custom ITC shell was taken, since it bills separately as V5275 where the payer allows.
• Laterality: The ear fitted, recorded in the chart so it matches the RT or LT modifier on the claim.
• Proof of delivery: A patient signature confirming receipt, dated on the claim’s service date.
• PA number: Where PA is required, a valid approval number that covers the service date.

ICD-10 diagnosis codes used with V5243

Every V5243 claim needs at least one ICD-10-CM code that documents hearing loss. The H90 and H91 families are the standard companions, but each payer may restrict the accepted codes in its medical policy.

Code to the highest level of specificity the audiogram supports. If testing shows sensorineural loss in the right ear only, use H90.41 rather than H90.3. A diagnosis that matches the RT or LT modifier makes a laterality denial far less likely.

How to bill HCPCS code V5243: Units, modifiers and claim setup

V5243 is billed as one unit per aid, on its own claim line, with the RT or LT modifier. Audiology claims management software that checks modifiers and units before submission catches most setup errors before the payer does.

Follow the payer’s own billing manual when it differs from these defaults. A few Medicaid programs publish code-specific instructions for laterality and dispensing fees. Provider eligibility also varies, since some states let hearing instrument specialists bill and others enroll only audiologists or DME suppliers.

Common reasons V5243 claims are denied

Most V5243 denials are predictable. The table below maps the leading causes to their fixes. For the remittance side, cross-reference each adjustment reason against the medical billing denial codes.

Replacement frequency and benefit period rules for V5243

Replacement rules decide how often a patient can receive a new aid under their coverage. Because V5243 covers one ear, the benefit clock usually runs per ear, not per pair. Replacing one lost aid from an analog ITC pair bills as V5243 with that ear’s modifier, not as V5249.

For an early replacement, the record must state the clinical reason and the ear affected. A new audiogram showing a threshold shift carries far more weight than a chart note saying the aid was lost. For theft, attach the police report.

V5243 in 2026: Code status and reimbursement

V5243 is active for 2026. Its descriptor has not changed since CMS added the V5241-V5275 series in 2002.

Reimbursement for V5243 is set payer by payer and changes at least once a year. Pull current amounts from each payer’s published fee schedule rather than relying on last year’s figures.

How claims management software prevents V5243 denials

A V5243 claim rests on three details that different people record: the ear fitted, the circuitry type and the PA number. The audiologist notes the ear, the supplier’s specification sheet confirms the circuitry and the front desk holds the PA. If one detail never reaches the biller, the claim goes out under the wrong code or modifier.

Pabau keeps those details on one patient record. Digital forms capture the order, the device details and the ear fitted before the appointment ends. The audiogram and PA approval sit on the same record, so staff can find them when the claim is built.

Pabau’s claims management then submits the claim electronically and tracks its status. Your billing team can see where each V5243 claim sits and follow up on a denial before the appeal window closes.

Keep every hearing aid claim on the right code

Pabau stores the audiogram, device specification and PA number on one patient record, then submits and tracks each claim so your team catches denials early.

Conclusion

V5243 is only the right code when three facts line up: one ear, an ITC shell and conventional analog circuitry. The circuitry is the fact most likely to be wrong, because most ITC aids dispensed today are programmable or fully digital.

Settle it from the specification sheet at the fitting, then carry the ear into the PA request and onto the claim as RT or LT. When both ears get analog ITC aids, switch to V5249 rather than billing V5243 twice.

If your team still matches fitting notes to payer rules by hand, one patient record removes that step. Book a demo to see how Pabau keeps hearing aid documentation and claims together for your audiology practice.
