HCPCS code V5190 – Spectacle-mounted hearing aid with CROS

Key takeaways

HCPCS Code V5190 covers a monaural CROS hearing aid built into eyeglass frames, not a BTE, ITE or ITC device.

Monaural CROS aids in other styles bill as V5181 (BTE), V5171 (ITE) or V5172 (ITC), and a binaural glasses BiCROS system bills as V5230.

Medicare Part B excludes hearing aids, including V5190, under Section 1862(a)(7) of the Social Security Act. Some Medicare Advantage and state Medicaid plans do cover it.

A missing audiogram, the wrong device-style code and absent prior authorization are the three leading causes of V5190 denials.

Practice management software like Pabau keeps the audiogram, order and PA number on one patient record, so each V5190 claim goes out complete.

HCPCS Code V5190: Official descriptor and code family

HCPCS Code V5190 is the Level II code for a monaural contralateral routing of signals (CROS) hearing aid built into eyeglass frames. 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, contralateral routing, monaural, glasses.

Each part of that descriptor narrows the code. Contralateral routing means a microphone on the poorer ear sends sound across to the better-hearing ear. Monaural means only the better ear has a receiver, which separates CROS from BiCROS. Glasses means the components sit in eyeglass frames.

The table below places V5190 among the neighboring codes that coders most often confuse with it.

Mounting style decides the code. A behind-the-ear CROS system bills as V5181, and an in-the-ear one as V5171. When the CROS components sit in eyeglass frames, V5190 applies. Billing the wrong mounting code is the most preventable denial on CROS claims, and the code map below lays out each option side by side.

What HCPCS Code V5190 covers and what it excludes

V5190 covers one device configuration. The components must be built into eyeglass frames, and the device must route sound from a nonfunctional or profoundly impaired ear to the better-hearing ear.

• Included: A glasses-mounted CROS transmitter and receiver dispensed as one unit to a patient with single-sided deafness (SSD) or profound unilateral hearing loss
• Excluded: The dispensing fee, which has its own code, V5200 (dispensing fee, contralateral, monaural). Check whether each payer bundles it
• Excluded: Other monaural CROS styles, which bill as V5181 (BTE), V5171 (ITE) or V5172 (ITC)
• Excluded: Binaural BiCROS systems in eyeglass frames, which bill as V5230
• Excluded: Accessories and supplies billed separately, such as batteries, ear hooks and tubing. Use V5267 or an accessory-specific V code
• Excluded: Bone-anchored hearing devices and cochlear implants, which fall under separate HCPCS ranges

BiCROS causes the most coding confusion. A BiCROS device serves a patient with hearing loss in both ears, where one side is much worse. The better ear also needs amplification, so it gets its own receiver. CROS has only one receiver. A BiCROS system in eyeglass frames bills as V5230, not V5190.

Clinical indications and patient eligibility for HCPCS Code V5190

V5190 is clinically appropriate for a patient with single-sided deafness or profound unilateral sensorineural hearing loss. A standard aid on the impaired side must offer no benefit. The audiogram must show that the affected ear falls below usable aided thresholds, which supports CROS as the right intervention.

The ICD-10-CM diagnosis codes most commonly paired with V5190 claims include:

• H90.3 Sensorineural hearing loss, bilateral (when both ears are documented but CROS targets the worse side)
• H90.41 Sensorineural hearing loss, unilateral, right ear
• H90.42 Sensorineural hearing loss, unilateral, left ear
• H90.5 Unspecified sensorineural hearing loss (use when laterality is not fully documented, though specific codes are preferred)
• H91.91 Unspecified hearing loss, unilateral, right ear
• H91.92 Unspecified hearing loss, unilateral, left ear

Payer policies vary on which ICD-10 codes they accept alongside V5190. Some commercial plans require the H90.4x unilateral codes specifically. Submitting H90.3 without documenting the difference in severity between ears can trigger a medical necessity denial. Confirm the diagnosis code requirements in the payer’s coverage policy before you submit.

Documentation requirements for V5190 claims

Insufficient documentation is one of the leading reasons HCPCS Code V5190 claims are denied. Audiology practices that standardize the documentation package before dispensing get paid faster. Most payers require the following:

• Audiogram: Pure-tone air and bone conduction thresholds for both ears, dated within six months of fitting or per payer specification. It must show the severity of impairment on the CROS side and residual hearing in the better ear
• Physician or audiologist order: A written order recommending a CROS hearing aid, signed by a licensed provider
• Certificate of Medical Necessity (CMN) or equivalent: Some payers require a completed CMN form, and others accept a detailed clinical note instead. Confirm per payer
• Device details: Manufacturer, model name and serial number for the dispensed spectacle CROS system
• Fitting notes: Documentation that the device was fitted and the patient received orientation on using it
• Patient acknowledgment: A signed statement confirming the patient understands their coverage limits, which matters most when Medicare is primary and excludes the device

Missing even one element frequently leads to a CO-4 or CO-50 denial and a resubmission. A documentation checklist built into the patient’s intake forms prompts staff to confirm each item before the claim goes out.

Prior authorization requirements for V5190 by payer

Prior authorization (PA) requirements for HCPCS Code V5190 vary significantly across payers. PA rules change with contract cycles, so treat the table below as a starting reference and verify with each payer before dispensing.

Verify eligibility and PA status before you dispense. Otherwise you risk fitting the device, submitting the claim and only then learning that PA was required. A retroactive PA denial on a spectacle CROS system is rarely reversible.

Medicare and Medicaid coverage for HCPCS Code V5190

Medicare Part B does not cover HCPCS Code V5190. Section 1862(a)(7) of the Social Security Act excludes hearing aids from Medicare coverage, and the exclusion applies to every hearing aid HCPCS code. No Medicare Local Coverage Determination (LCD) overrides it for spectacle CROS devices.

Three exceptions are worth knowing:

• Medicare Advantage (Part C): Individual plans may add hearing aid benefits beyond original Medicare. Check each plan’s coverage policy annually, as benefit structures change at open enrollment
• Medicaid state plans: Coverage varies widely. Louisiana’s Medicaid fee schedule explicitly references V codes for hearing devices, and Minnesota’s Department of Human Services volume purchase contract references hearing aid V codes. Many states with adult hearing aid benefits include CROS devices. Confirm with the state Medicaid agency or the patient’s managed care plan
• CHIP plans: Children’s coverage under CHIP varies by state and may include hearing aids with fewer restrictions than adult Medicaid

When Medicare is primary and the device is non-covered, document the Advance Beneficiary Notice (ABN) process. A signed ABN before dispensing protects your practice from carrying the financial risk. Flag Medicare patients for the ABN step at scheduling, before the fitting appointment.

Common claim denial reasons for V5190 and how to avoid them

V5190 has a predictable set of denial patterns. Most are avoidable with a pre-submission checklist tied to the device style and the payer’s requirements.

Every denial on a V5190 claim should become a worklist item. Identify the reason code, correct the cause and resubmit within the payer’s timely filing window. Denials left to age lose both the revenue and the appeal window. A reference to medical billing denial codes helps coders read the remittance advice and pick the right fix.

How to submit a V5190 claim correctly

Clean submission for HCPCS Code V5190 depends on a handful of fields that payers audit closely. Follow this sequence for commercial and Medicaid plans that cover the code:

1. Confirm coverage and PA status before dispensing. Verify benefits, record the PA approval number if required, and obtain any required ABN
2. Select the correct HCPCS code. Use V5190 for spectacle-mounted CROS only, and confirm the device model documentation matches the spectacle mounting style
3. Assign the modifier. Use the NU modifier (new equipment) for a newly dispensed device. Don’t apply LT/RT modifiers to hearing aid V codes, because laterality is conveyed through the ICD-10 diagnosis code
4. Pair the correct ICD-10 diagnosis code. Use the most specific unilateral sensorineural hearing loss code (H90.41 or H90.42), and make sure it matches the ear documented in the audiogram
5. Set the place of service. POS 11 (office) is typical for an audiology dispensing practice
6. Attach supporting documentation. Send the audiogram, physician order and CMN (if required) through the attachment process your payer uses
7. Submit via 837P or CMS-1500, per the payer’s accepted format. Confirm your billing system produces a clean claim before transmitting

A clearinghouse that validates HCPCS codes against the current CMS file catches code-level errors before the claim reaches the payer. A clearinghouse rejection takes hours to fix, while a payer denial takes weeks.

CROS vs. BiCROS: Choosing the right HCPCS code

CROS and BiCROS are clinically distinct, and that distinction drives code selection. Getting it wrong is a quick route to a CO-11 denial.

Spectacle BiCROS systems have their own code, V5230 (hearing aid, contralateral routing system, binaural, glasses). Bill it instead of V5190 whenever the better ear also has a receiver. Payer coverage for V5230 varies as widely as it does for V5190. Describe the exact device configuration in the prior authorization request, and keep the payer’s written response in the patient’s record.

How claims management software prevents V5190 denials

A V5190 claim often lives in three places at once: the fitting notes, a payer spreadsheet and the clearinghouse portal. When the audiogram sits in one and the PA number in another, the claim goes out incomplete.

Practice management software like Pabau keeps those pieces on the patient record. Digital forms capture the provider order, the device details and the signed coverage acknowledgment before the fitting. The audiogram is stored against the same record, so staff can find it when the claim is built.

Pabau’s audiology claims software then submits the claim electronically and tracks its status. Your billing team can see where each V5190 claim sits and follow up on a denial before the appeal window closes.

Bill CROS hearing aids without chasing paperwork

Pabau keeps the audiogram, order and PA number on the patient record, then submits and tracks each hearing aid claim so denials get caught early.

Conclusion

V5190 is only the right code when the CROS hardware sits in eyeglass frames and just one ear gets a receiver. Confirm both at the fitting rather than at billing, and wrong-code denials largely disappear.

Coverage is the harder call. Medicare Part B won’t pay, so the ABN and a clear self-pay conversation matter as much as the code. With every other payer, PA and a complete audiogram decide whether you’re paid on the first pass.

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