Top Denials in Ophthalmology Billing Services for Eye Practices and Surgery Centers

Should an Eye Exam Be Billed with 92014 or with an E/M Code?

Pick one family per visit, never both. The NCCI Medicare Policy Manual, chapter XI, says that when an E/M code is reported, the general ophthalmological codes 92002 to 92014 are not reported separately, because the E/M includes them. Special ophthalmological services, such as imaging and visual fields, may be reported separately.

The 2026 CMS fee schedule file (RVU26D, released 08/26/2026) lists 92002, 92004, 92012 and 92014 with status A, PC/TC indicator 0 and a global period of XXX, so no postoperative days attach to the exam. The 92014 code page covers the comprehensive established visit. Choose by payer rule and the work documented, then keep to that rule.

Our medical coding team sets one visit family per payer before the claim is built.

Who Pays for the Refraction, and When Do We Need an ABN?

The patient pays for 92015 when Medicare is the payer. The Medicare Benefit Policy Manual, chapter 16, section 90, excludes eye refractions by whatever practitioner and for whatever purpose, and the 2026 fee schedule file gives 92015 status N, which CMS defines as a non-covered service. The same section says the exclusion does not apply to physicians' services performed in conjunction with an eye disease such as glaucoma or cataracts, so the medical exam stays billable.

An ABN is not required for a statutory exclusion. Claims Processing Manual chapter 30, section 50.2.1, says CMS strongly encourages one for care that is never covered. On the claim, HCPCS modifier GY means the service is statutorily excluded. The denial is expected, with CARC 96, non-covered charges, as the usual reason, and the charge moves to the patient.

How Do We Bill Cataract Surgery and the 90-Day Global Period?

Bill one cataract code per eye and let the 90-day global period cover routine follow-up. NCCI chapter VIII says the codes 66830 to 66991 are mutually exclusive and only one may be reported for an eye. The 2026 CMS file shows 66984 (standard) and 66982 (complex) as status A with a 090 global, while 66983 has status C, so the MAC prices it. Claims Processing Manual chapter 12, section 40.1, says the global covers related preoperative visits, intraoperative services, complications that do not need a return to the operating room, and recovery visits.

Bilateral indicator 1 means the 150 percent adjustment applies when both eyes are reported on one day. Assistant indicator 1 is a statutory restriction, so an assistant at surgery may not be paid.

NCCI chapter VIII bundles an iridectomy done to complete the extraction, minimal vitreous loss, and any antibiotic or steroid injection given during surgery, so 67028 is not added for it. A distinct trabeculectomy for glaucoma can be reported with a PTP-associated modifier when the record shows separate necessity.

For Kentucky and Ohio, CGS LCD L33954 requires documented visual impairment from the cataract that limits daily activities. It lists acuity of 20/50 or worse as one path, applies the same criteria to the second eye, and says immediate sequential bilateral surgery is an individual decision that must be documented.

How Do Modifiers 54 and 55 Work When Another Doctor Comanages the Patient?

Modifier 54 means surgical care only and 55 means postoperative management only. Chapter 12, section 40.2 says both bills carry the same date and the same surgical code, so the surgeon bills 66984-54 and the comanaging doctor bills 66984-55. The date care changed hands goes in the remarks field, and both doctors keep the written transfer agreement. The receiving doctor cannot bill until he or she has provided at least one service.

RVU26D lists 10 percent preoperative, 70 percent intraoperative and 20 percent postoperative for 66984 and 66982. Under section 40.4 a surgeon billing -54 is paid the preoperative plus intraoperative portions, 80 percent here, and the postoperative portion is split by days of care. Split global care does not apply to 000-day codes, so there is no 54 or 55 on an injection.

The comanaging doctor paid with -55 uses modifier 24 for any unrelated visit. Modifier 79 reports an unrelated procedure in the period, 78 a return to the operating room for a related procedure, and 58 a staged procedure.

How Do We Charge a Patient for a Premium Lens?

Bill Medicare for the conventional lens procedure and report the extra function on separate HCPCS lines the patient pays. Claims Processing Manual chapter 32, section 120, says that under CMS Ruling 05-01 and CMS-1536-Ruling beneficiaries may pay additional charges for presbyopia-correcting and astigmatism-correcting lenses. The CPT code stays the one used for a conventional lens, such as 66984, and the extra charge is reported with V2788 (presbyopia-correcting) or V2787 (astigmatism-correcting).

Contractors deny those V-code lines with MSN 16.10 and CARC 96, so the denial is expected. Section 120.1 adds that a physician cannot bill Medicare for a premium lens placed in a hospital, that no benefit category covers extra monitoring beyond a conventional lens, and that an ambulatory surgery center presenting a bill for any lens is subject to a civil money penalty. See the ASC billing page.

Medicare covers one pair of conventional glasses or contact lenses after each cataract surgery with a lens (Benefit Policy Manual, chapter 15, section 120). Keep the signed price agreement in the chart before the day of surgery.

How Do We Bill Intravitreal Injections with the Drug?

Bill 67028 for the injection and a separate drug line, with units taken from the HCPCS descriptor. The 2026 file lists 67028 as status A with a 000 global, so it pays the procedure only. The October 2026 HCPCS file lists J0178 (aflibercept, 1 mg), J2778 (ranibizumab, 0.1 mg), J2777 (faricimab-svoa, 0.1 mg), J0179 (brolucizumab-dbll, 1 mg), J9035 (bevacizumab, 10 mg) and Q5124 (ranibizumab biosimilar, 0.1 mg). A drug billed per 1 mg and dosed at 2 mg is two units.

Claims Processing Manual chapter 17, section 40, requires JW on a separate line for discarded amounts from single-dose containers, and since July 1, 2023 JZ to attest that nothing was discarded. The oncology page covers the mechanics.

NCCI chapter VIII bars 67028 with paracentesis codes 65800 to 65815 on the same eye and with subconjunctival injection 68200 on the same side. Billing article A52451 (listed for Wellpoint Federal, jurisdictions 6 and K) says 67028 goes on the same claim as the drug and must carry RT, LT or 50, or the claim is returned unprocessed.

How Do We Use RT, LT, 50 and E1 to E4 on Eye Claims?

RT and LT name the eye, 50 reports both eyes on one line, and E1 to E4 name the eyelid. The HCPCS file defines E1 as upper left, E2 as lower left, E3 as upper right and E4 as lower right eyelid. See the RT and LT pages.

NCCI chapter VIII says bilateral ophthalmic procedures use modifier 50 with one unit on a single line, and eyelid procedures use E1 to E4. Chapter 12, section 40.7, adds that a code whose descriptor already says bilateral is not reported with 50. NCCI also says entropion or ectropion repair is reported with excision and repair of an eyelid only on a different eyelid, shown with E1 to E4, and that trichiasis codes count the eye, not the eyelid. Some MACs set their own preference by code, so follow the written article.

How Do 26 and TC, and One Eye Versus Both Eyes, Work on Tests?

Most ophthalmic tests have PC/TC indicator 1, so you bill globally when you own the equipment and the reading, or split with 26 and TC. The file shows indicator 1 for 92133, 92134, 92250, 92235, 92081 to 92083, 92025, 76512 and 92136. 92227 is technical only (indicator 3).

Bilateral indicator 2, given to 92133, 92134, 92250, 92235 and the visual field codes, means the RVUs already assume both eyes, so a second line is not paid extra. 76512 has indicator 3, so each eye is paid separately. NCCI chapter XI makes visual fields one unit that includes both eyes. Multiple procedure indicator 7 cuts the second and later technical components of ophthalmic tests by 20 percent.

OCT denies on medical necessity under the local policy. CGS LCD L34061 (Kentucky and Ohio) does not cover imaging that only confirms a known diagnosis, calls it unnecessary in advanced glaucoma where visual fields apply, and says imaging and visual fields on the same day or within three months are usually not medically necessary. See the 92134 page. NCCI chapter XI treats 92250 and OCT as mutually exclusive unless both are necessary, then 92250 takes 59 or XU, and angiography such as 92235 includes the IV and dye injection.

How Do Medicare and Commercial Rules Differ for Eye Claims?

Medicare sets the baseline and the MAC LCD decides necessity; the filing limit is 1 calendar year after the service under 42 CFR 424.44. See the Medicare billing guide. UnitedHealthcare's prior authorization page lists cardiology, oncology, radiology, genetic and molecular testing and gastroenterology programs and no eye program as of October 25, 2026; injected drugs follow separate drug policies, so check the plan. See the UnitedHealthcare guide and our prior authorization service.

Commercial and Medicare Advantage contracts can differ on exam codes, refractions, bevacizumab-first rules and comanagement. Contract language wins over a general guide.
