HCPCS code V2628 – Prosthetic eye, plastic, custom

Key Takeaways

HCPCS code V2628 applies specifically to a custom plastic prosthetic eye, distinguishing it from stock prostheses and from V2629, which covers non-plastic or other-type prosthetic eyes.

Only DMEPOS-enrolled suppliers, typically certified ocularists or prosthetic device suppliers, may bill V2628. Ophthalmology practices billing professional services on a CMS-1500 cannot use this code.

Every V2628 claim requires a laterality modifier (LT or RT) plus an NU or RP modifier, a supporting ICD-10 diagnosis code, a physician order, and documented proof of the underlying surgical procedure.

Pabau’s claims management software helps ocularist practices and DMEPOS suppliers track claim status, flag missing modifiers before submission, and manage denial workflows from one dashboard.

HCPCS code V2628: Definition and official descriptor

HCPCS code V2628 is the Level II alphanumeric code maintained by the Centers for Medicare and Medicaid Services (CMS) for a prosthetic eye made of plastic, custom-fabricated to fit an individual patient’s ocular socket. The “custom” designation in the descriptor is not incidental. It is the clinical and billing distinction that separates V2628 from stock prosthetic eye codes and from V2629, which covers other material types.

V2628 sits within the V2600-V2629 series of HCPCS codes covering low vision aids and ocular prosthetic devices. It is billed on a DMEPOS claim, not on a professional services claim form.

What V2628 covers and what it does not

V2628 covers the supply of one custom-fabricated plastic prosthetic eye delivered to a patient whose eye has been surgically removed or whose socket requires prosthetic restoration. Custom fabrication means the prosthesis is individually made and fitted to the patient’s specific socket dimensions and cosmetic characteristics by a certified ocularist.

An ocular conformer is a smooth, clear shell placed in the socket immediately after surgery to maintain socket shape during the healing period. It is not a cosmetic prosthesis and is never billed under V2628. Failing to separate the conformer and the custom prosthesis onto different claims is a common unbundling error that triggers audits.

V2628 vs V2629 and related prosthetic eye codes (V2621-V2629)

The single most common coding error on prosthetic eye claims is selecting V2629 when V2628 is correct, or vice versa. The distinction is material type and fabrication method: V2628 is plastic and custom; V2629 is any other type. When the prosthesis is glass, acrylic of a non-plastic classification, or any material outside the plastic category, V2629 applies.

When an ocularist’s invoice specifies plastic and custom fabrication, V2628 is the correct code. If the documentation does not confirm the material as plastic, bill V2629 and note the actual material in the claim notes field.

Who can bill V2628: Eligible suppliers and providers

V2628 is a DMEPOS code, which means only suppliers enrolled in Medicare as DMEPOS suppliers may bill it. This is a hard eligibility rule. Ophthalmology physician practices billing professional services on the Medicare Physician Fee Schedule cannot bill V-series HCPCS codes for prosthetic devices.

• Certified ocularists with DMEPOS enrollment: The primary eligible billers. Board-certified ocularists who also hold CMS DMEPOS supplier accreditation may bill V2628 for custom prostheses they fabricate and deliver.
• Prosthetic and orthotic suppliers: P&O suppliers with appropriate DMEPOS accreditation may also bill V2628 when they supply custom plastic prosthetic eyes.
• Hospital outpatient departments: When a hospital DMEPOS supplier department provides the prosthesis, it bills on the appropriate institutional claim, not under a physician NPI.
• Ophthalmologist offices: Not eligible to bill V2628 on a CMS-1500 for professional services. If the physician writes the order, the DMEPOS supplier bills the device code.

Proper understanding of medical billing workflows at the supplier level prevents the common error of a physician practice billing the device code alongside the professional service, which triggers CO-4 or CO-11 denials.

Required ICD-10 diagnosis codes for V2628

Every V2628 claim requires at least one ICD-10-CM diagnosis code that establishes medical necessity. Payers validate that the diagnosis supports the need for a prosthetic eye. Missing or mismatched diagnosis codes are the second most common denial cause after incorrect code selection.

Z89.011 and Z89.012 are the most commonly accepted codes under DME MAC Local Coverage Determinations (LCDs) for prosthetic eye coverage. The laterality in the ICD-10 code must match the laterality modifier on the HCPCS code. A claim with Z89.011 (right eye) but modifier LT (left) will deny on mismatch.

Modifiers required when billing V2628

HCPCS code V2628 requires two modifier types on every claim: A laterality modifier identifying which eye received the prosthesis, and a supply status modifier indicating whether this is a new device or a replacement. Submitting V2628 without both modifiers is one of the fastest paths to a CO-4 denial.

Apply LT or RT first, then NU or RP as the second modifier. Some DME MACs require the modifiers in this exact sequence. Confirm your MAC’s Local Coverage Determination for any jurisdiction-specific sequencing rules before submission.

Documentation requirements for a clean V2628 claim

Documentation failures cause more V2628 denials than incorrect code selection. A clean claim for a custom plastic prosthetic eye requires the following records to be on file before submission, not assembled after a denial.

1. Physician order or prescription: A written order from a treating physician (ophthalmologist or surgeon) specifying the need for an ocular prosthesis and identifying the affected eye. The order must predate the delivery of the prosthesis.
2. Proof of surgical procedure: Operative report or discharge summary documenting enucleation, evisceration, or exenteration. This establishes the medical necessity foundation required by most DME MAC LCDs.
3. Ocularist’s fitting and fabrication notes: Documentation confirming that the prosthesis was custom-fabricated, including socket impressions, fitting appointments, and delivery confirmation.
4. Diagnosis documentation: The treating physician’s records confirming the ICD-10 diagnosis (e.g., Z89.011, H84.01) that justifies the prosthesis.
5. Supplier invoice: The ocularist or supplier invoice showing the specific prosthesis delivered, confirming it is plastic and custom-fabricated, and the date of delivery.
6. Medicare Assignment Agreement (if applicable): Medicare Part B requires suppliers to accept assignment for prosthetic devices in most circumstances.

Under medical billing compliance requirements, all documentation must be retained for a minimum of seven years and must be available for MAC audit requests. Some LCDs require a detailed written order (DWO) rather than a standard prescription. Check your DME MAC’s specific LCD for the required documentation format.

Prior authorization and frequency limits for V2628

Medicare Part B does not require prior authorization for the initial supply of a custom prosthetic eye under most DME MAC LCDs. The National Coverage Determination (NCD 150.1) covers artificial eyes, and coverage is considered medically reasonable and necessary following surgical eye removal.

Replacement frequency is a different matter. Most DME MAC LCDs allow one replacement prosthetic eye every five years under Medicare, absent documented medical necessity for earlier replacement. Replacement before the five-year limit requires documentation of one of the following conditions.

• Irreparable damage to the prosthesis from an accident or medical condition
• Significant socket changes following surgery, illness, or weight change that make the existing prosthesis non-functional
• Documented growth in a pediatric patient requiring a larger prosthesis
• Prosthesis beyond repair after polishing and adjustment attempts

Medicaid programs have varying prior authorization requirements. Several state Medicaid programs require prior authorization for any prosthetic eye supply, including initial provision. Confirm requirements with the specific state Medicaid MAC before submission. Private payers also vary. Many commercial plans require prior authorization and have different replacement frequency limits, sometimes as short as three years.

Medicare fee schedule and reimbursement for V2628 (2025-2026)

HCPCS code V2628 is reimbursed under the Medicare Part B DMEPOS Fee Schedule, not the Physician Fee Schedule. Rates are set by CMS and updated annually. The CMS Physician Fee Schedule search tool covers professional services. For DMEPOS allowables, use the CMS DMEPOS fee schedule files published each year on the CMS website.

Key reimbursement facts for V2628 under Medicare Part B.

• Fee schedule type: Medicare DMEPOS fee schedule (not the physician RVU-based fee schedule)
• Patient cost share: Medicare Part B covers 80% of the approved amount after the annual deductible; the patient or secondary insurance is responsible for the remaining 20%
• Assignment: DMEPOS suppliers accepting Medicare assignment must accept the Medicare-allowed amount as payment in full
• Rate variation: DMEPOS allowables vary by geographic locality; rural and non-competitive acquisition program areas may have different rates
• Annual updates: CMS publishes DMEPOS fee schedule updates each calendar year; verify current-year rates in the CMS DMEPOS fee schedule file before quoting patients

Use the AAPC HCPCS code lookup to cross-reference V2628’s descriptor and confirm the current status of the code for the billing year. For current-year allowable amount lookups, the PGM Billing HCPCS lookup tool pulls directly from CMS published data.

Common V2628 claim denials and how to resolve them

HCPCS code V2628 has a predictable set of denial patterns. Most practices that bill prosthetic eye codes regularly see the same five or six denial reasons cycling through their AR. Understanding the root cause of each denial shapes the resolution strategy and, more importantly, shapes the pre-submission workflow that prevents recurrence. Tracking denial management patterns across V2628 claims is the fastest way to identify systemic documentation gaps.

See the full denial code reference for CARC/RARC code definitions and resolution workflows. For V2628 specifically, the laterality mismatch and wrong-code errors together account for the majority of first-pass denials in most ocularist practices.

How V2628 fits into the prosthetic eye fitting and replacement workflow

Understanding where HCPCS code V2628 sits in the clinical timeline prevents the most common workflow-level billing errors: Billing the custom prosthesis too early, bundling separate service codes, and missing interim codes that apply before V2628 is appropriate.

1. Surgical procedure (enucleation, evisceration, or exenteration): The surgeon performs the surgical removal or debulking of the eye or orbit. CPT codes cover this phase. HCPCS codes do not apply here. The operative report from this stage is the foundational document for all subsequent prosthetic billing.
2. Immediate post-surgical conformer: Within days of surgery, an ocular conformer is fitted to maintain socket shape during healing. This is billed under a separate HCPCS code for conformers, not under V2628. The conformer and the custom prosthesis are always separate claims.
3. Healing period (typically 6-12 weeks): The socket heals before custom prosthesis fabrication begins. No HCPCS device code applies during this period, though follow-up professional service CPT codes may apply for the ophthalmologist’s visits.
4. Custom fabrication by certified ocularist: The ocularist takes socket impressions, fabricates the custom plastic prosthesis, and conducts fitting appointments. All fitting notes and fabrication records are created in this stage. These records are what substantiates the “custom” designation required for V2628.
5. Delivery and fitting confirmation: The prosthesis is delivered and final fitting is confirmed. The delivery date is the service date for the V2628 claim. The supplier invoice and fitting notes are finalized and filed.
6. Claim submission: The DMEPOS-enrolled supplier submits V2628 with the appropriate laterality modifier (LT or RT), supply status modifier (NU for new, RP for replacement), the linked ICD-10 diagnosis code with matching laterality, and all supporting documentation on file.

Pabau’s claims management software supports this multi-step workflow by allowing practices to attach documentation to individual claims, track stage-by-stage claim progress, and flag incomplete records before submission. For practices managing both the clinical and billing sides of prosthetic eye supply, centralising the documentation against the claim record cuts the rework time when a denial arrives.

Conclusion

HCPCS code V2628 is a narrow, specific code: Plastic, custom-fabricated prosthetic eye, billed by an enrolled DMEPOS supplier, supported by a physician order, laterality modifiers, a matched ICD-10 diagnosis, and documentation confirming custom fabrication. Most denials come from a small set of preventable errors: Wrong code (V2629 instead of V2628), missing or mismatched modifiers, and documentation assembled after the fact.

Practices that build a pre-submission documentation checklist around V2628’s requirements, track replacement frequency limits per patient, and manage denials through a structured workflow reduce their AR days and rework. Pabau’s claims management software helps DMEPOS suppliers and ocularist practices do exactly that. Book a demo to see how the workflow fits your practice.
