HCPCS code V2311 – Sphere bifocal lens billing guide

Key takeaways

V2311 bills one trifocal spherocylinder lens per eye, with a sphere of ±7.25 to ±12.00D and 0.25 to 2.25D of cylinder.

V2300-V2399 is the trifocal lens range, so bifocals belong in V2200-V2299 and sphere-only trifocals use V2300-V2302.

Medicare excludes routine eyeglasses and covers V2311 only for pseudophakia after cataract surgery, aphakia or congenital aphakia.

Medicare claims need RT or LT on separate lines with one unit each, and KX is not required on V2311.

Pabau’s claims management software pulls patient, treatment and insurer details from the record into a pre-filled claim and tracks it to payment.

HCPCS code V2311: official descriptor and code definition

HCPCS code V2311 is the Healthcare Common Procedure Coding System (HCPCS) Level II code for one trifocal spherocylinder spectacle lens. CMS lists it in the V2300-V2399 trifocal lens range of the V-series vision codes. Our HCPCS code reference sets out the other V-series lens codes in the same format. A trifocal gives three zones of correction in one lens: distance, intermediate and near.

The official CMS descriptor reads: Spherocylinder, trifocal, plus or minus 7.25 to plus or minus 12.00d sphere, .25 to 2.25d cylinder, per lens. Spherocylinder means the lens corrects astigmatism as well as nearsightedness or farsightedness. The code describes the lens only, not the frame, the dispensing fee or the eye exam.

Descriptor and pricing indicator are taken from the CMS HCPCS alpha-numeric file, October 2026 release.

Where V2311 fits in the trifocal lens range

Trifocal lenses take codes V2300 through V2399, and bifocals sit one range lower, in V2200 through V2299. Inside the trifocal range, two numbers from the prescription decide the code: the sphere power and the cylinder power. The table below lists the neighbors billers confuse most often with V2311.

Two boundaries need care. The CMS descriptors for V2311 and V2312 both include a 2.25D cylinder, so a 2.25D prescription fits either text. Ask the payer which code it expects at that value, and apply its answer on every claim. The chart below shows where the three cylinder bands meet.

The sphere value also changes when a prescription is transposed between plus-cylinder and minus-cylinder notation. A +8.00 −1.50 × 090 prescription becomes +6.50 +1.50 × 180, which drops below the V2311 sphere band. Keep the prescription, the lab order and the claim in one notation, so an auditor reads the same sphere value you coded.

V2320 describes a trifocal add over 3.25D. It covers the near-power add rather than a sphere or cylinder band, so it never replaces V2311 as the base lens code. If the prescription carries no cylinder at all, the lens is a sphere trifocal and takes V2300, V2301 or V2302.

What V2311 covers and what it excludes

Knowing what falls outside V2311 prevents the most common selection errors in trifocal dispensing.

• Covered: a trifocal spherocylinder lens with a ±7.25 to ±12.00D sphere and a 0.25 to 2.25D cylinder, billed per lens.
• Covered: plus and minus prescriptions alike, since the descriptor reads plus or minus.
• Not V2311: a sphere-only trifocal with no cylinder, which takes V2300, V2301 or V2302.
• Not V2311: a bifocal lens, which falls in V2200-V2299, or a progressive lens, which uses V2781.
• Not V2311: a sphere over ±12.00D, which takes V2314, or a cylinder above 2.25D, which takes V2312 or V2313.
• Not V2311: tints, coatings and other lens options such as V2745 or V2750, which are billed on their own lines.
• Not V2311: the frame, the dispensing fee or the refraction.

Medicare coverage and reimbursement for V2311

Medicare does not cover routine eyeglasses. Section 1862(a)(7) of the Social Security Act excludes them, so a V2311 lens for a routine prescription change is a non-covered service.

The exception sits in Section 1861(s)(8), which treats post-cataract lenses as prosthetic devices. Medicare covers one pair of eyeglasses or contact lenses after each cataract surgery with insertion of an intraocular lens. The DME MAC Refractive Lenses LCD (L33793) also covers lenses for aphakia and congenital aphakia.

• Who pays: Medicare claims for refractive lenses go to the DME MAC for the beneficiary’s region, under LCD L33793 and policy article A52499.
• How it is priced: the CMS HCPCS file gives V2311 pricing indicator 38, which places it on the DMEPOS fee schedule.
• Coverage status: the same file marks V2311 as carrier judgment, so the DME MAC policy decides when it is payable.
• Frequency: one pair is covered after each cataract surgery, so surgery on the second eye opens a new allowance.

Medicaid, Medicare Advantage and commercial vision plans

Outside traditional Medicare, coverage depends on the plan. Medicare Advantage plans often add a routine eyewear benefit, but each plan sets its own rules. State Medicaid programs set their own vision benefits, including which adults qualify for eyeglasses.

Commercial vision plans usually cover one pair of lenses per benefit period, often every 12 or 24 months. Medicare Part B does not require prior authorization for refractive lenses. Some Medicare Advantage, Medicaid and commercial vision plans do, so check the plan before you order the lenses.

Diagnosis codes that pair with V2311

The right diagnosis depends on who pays. Medicare covers V2311 only when the natural lens is missing, while vision plans pay on H52 refraction codes such as H52.4. The table below separates the two.

A Medicare claim that carries only H52 refractive codes is denied, because those codes describe routine vision. Use the CDC/NCHS ICD-10-CM web tool to confirm each code is valid for the date of service.

Applicable modifiers for V2311

Medicare DME MACs require RT or LT on V2311. Each lens goes on its own claim line with one unit, and a single RTLT line is rejected as incorrect coding.

KX is not required on V2311. Policy article A52499 limits KX to lens-option codes such as V2744, V2745, V2750, V2780 and V2784. Commercial plans set their own modifier rules, so check each plan before you apply RT or LT there.

Documentation requirements for V2311 claims

Payers expect the following records behind every V2311 line. A missing item is the usual reason a post-payment review recoups the claim.

• Written prescription: dated and signed by the treating physician or optometrist, listing sphere, cylinder, axis and add for each eye.
• Diagnosis support: for Medicare, records showing pseudophakia, aphakia or congenital aphakia, with the cataract surgery date where it applies.
• Lens specification: the lab order or invoice, showing a trifocal spherocylinder lens and the powers made for each eye.
• Proof of delivery: a delivery record signed by the patient, because the date of service on a DME MAC claim is the delivery date.
• Per-eye coding: one line per lens with RT or LT, and a separate code if the other eye falls in a different band.
• DME MAC standards: orders, medical records and proof of delivery follow policy article A55426 for every DME MAC claim.

How to bill HCPCS code V2311: step-by-step

Follow these steps in order to avoid the most common submission errors on trifocal spherocylinder lenses.

1. Read the prescription for each eye: confirm a trifocal, a sphere of ±7.25 to ±12.00D and a cylinder of 0.25 to 2.25D.
2. Check the boundaries: apply the payer’s rule to a 2.25D cylinder, and recheck the sphere if the prescription was transposed.
3. Confirm the payer: Medicare needs a post-cataract or aphakia diagnosis, while vision plans set their own benefits and authorization rules.
4. Select the diagnosis: enter Z96.1, an H27.0- code or Q12.3 for Medicare, or the matching H52 codes for a vision plan.
5. Build the claim lines: enter V2311 in Box 24D of the CMS-1500 or the 837P SV1 segment, one unit per line, with RT or LT.
6. Link the diagnosis: point each line in Box 24E to the diagnosis in Box 21, and set the date of service to the delivery date.
7. Add lens options separately: bill tints, coatings and other options on their own lines with their own codes and modifiers.
8. Submit and track: send the claim through claims software with tracking or your clearinghouse, then watch the 835 remittance for denials.

Common denial reasons for V2311 and how to fix them

V2311 denials follow a predictable pattern. The table below maps each one to its cause and fix. The adjustment codes are illustrative, since each payer applies its own.

A structured denial management process that tracks these codes by lens code shows recurring errors early. One example is a 2.25D cylinder coded as V2311 on one claim and V2312 on the next. Route those findings back into your medical billing workflows so the fix sticks.

How Pabau keeps V2311 claims clean before they go out

Most V2311 errors start before the claim exists. The prescription lives in the exam notes, the lens order goes to the lab, and the biller re-keys the details by hand.

Pabau, the practice management platform we build, keeps the prescription, the diagnosis and the dispensing record on one patient file. Its claims management software pulls the patient, treatment and insurer details from that record into a pre-filled submission. Validation checks run each time you send a claim, so missing details such as authorization codes surface before the payer sees them.

For US practices, Pabau submits claims through Claim.MD, runs real-time eligibility checks and posts ERA remittances. Each claim shows its status from pending to paid, which keeps revenue cycle management in one place. Fewer re-keyed values mean fewer avoidable denials and more clean claims on the first pass.

Send cleaner trifocal lens claims

Pabau pulls patient, treatment and insurer details from the record into a pre-filled claim and checks it before submission. Your team spends less time reworking V2311 denials.

Conclusion

V2311 rewards precision. Code from the written prescription, one eye at a time, and check both numbers against the band. Settle the 2.25D cylinder and any transposed prescription once, in writing, rather than claim by claim.

For Medicare, the diagnosis decides payment before the lens does, so confirm pseudophakia or aphakia before you bill a DME MAC. Book a demo to see how Pabau keeps prescription, diagnosis and claim details together so trifocal lens claims go out clean.
