Complying with Eye Care Guidelines

Eye care services sit at the intersection of high volume and high audit risk. These ten service areas are where documentation, coding, supervision, and coverage rules most often break down—making them critical compliance focus points for 2026.

1. Eye Codes vs. E/M Codes

Medicare coding is a lot different for vision services than (MA) Medicare Advantage or private vision coverage. Routine eye services (e.g., eyeglasses, contacts) are non-covered. CMS coverage focuses on diagnosing and treating eye‑related conditions such as glaucoma and cataracts.

An ophthalmologist or optometrist may bill either an E/M Service (99202–99215) or an
eye exam code (92002–92014), whichever is most appropriate. Medical necessity for any E/M code submitted to Medicare (or eye code for that matter) must be supported in the medical record.

Documentation Tips:

  • E/M office visits (99202–99215) (post-2021) are selected by MDM or time. 
  • Eye visit codes (92002/92012 intermediate; 92004/92014 comprehensive) are a separate code family with their own documentation expectations for “intermediate” vs “comprehensive.”

Compliance Risk: Practices “default” to 920xx for most encounters without documenting the elements that support either intermediate or comprehensive exam, plus the initiation and/or continuation of diagnostic/treatment programs. Or they bill E/M without supporting MDM/time.

Pro Tip: Pick one code family per encounter and make sure the note structure supports it.

2. Refraction (Medicare Patients)

Medicare statutorily excludes refraction (92015) from coverage. To submit for a denial or to a secondary payer, you need an appropriately executed ABN and the “GY” modifier on your claim.

3. Glaucoma Screening (G0117/G0118)

G0117 – Glaucoma Screening performed by Optometrist or Ophthalmologist for High-Risk Patient

G0118 – Glaucoma Screening for High-Risk Patient directly supervised by an Optometrist or Ophthalmologist

Compliance Risk: High-risk criteria and frequency limitation

Pro Tips: Ensure the service meets frequency (once annually/every 12 months) and supports high risk (diabetes, family history, African‑American ≥50, Hispanic ≥65) in the medical record.

4. Visual Field Testing (CPT® 92081-92083)

Visual field testing looks for vision loss by checking how well the retina and optic nerve work. Testing measures how well a patient can see light in different parts of their vision (perimetry).

Compliance Tip:  Make sure the patient meets medical necessity criteria. These services have limited coverage (LCD Policy 34394).

Documentation Tip: Document condition to the highest level of specificity known.

5. OCT/SCODI 

Optical coherence tomography (OCT) is the most common method used to perform scanning computerized ophthalmic diagnostic imaging (SCODI). However, Medicare considers OCT to be a type of SCODI and applies all SCODI coverage, documentation, and frequency requirements under LCD L35038.

6. Cataract Surgery (CPT® 66984 / 66982)

Cataract surgery is a high‑volume, high‑audit service under Novitas JH, with denials most often driven by insufficient documentation of functional impairment, unsupported medical necessity, and failure to meet LCD L35091 requirements.
Top three denials:
  1. Missing or Weak Functional Impairment (ADLs)
  2. Insufficient Medical Necessity Documentation
  3. Excessive or Unsupported Pre‑Operative Testing

Pro Tip:  Review LCD 35091 Requirements

7. Intravitreal Injections (67028)

The biggest risk with Intravitreal Injections is reporting an E/M code on the same day that is not separately identifiable. An E/M may be billed with an intravitreal injection only when the visit includes significant, separately identifiable medical decision‑making beyond the routine work required to perform the injection.

Pro Tip:  The AAO has a comprehensive checklist to help practices navigate compliant coding and documentation of these procedures. Internal link only, our CDI team has created a tip sheet for Intravitreal Injection coverage by managed care plan.

8. OPT (Ocular Photodynamic Therapy) with Verteporfin

Medicare covers ocular photodynamic therapy (OPT) with verteporfin only for exudative (wet AMD) age‑related macular degeneration (H35.32). For follow‑up OPT with verteporfin, CMS requires pre‑treatment imaging using either FA (92235) or OCT (92133 or 92134); however, the imaging does not need to be billed on the OPT claim and may be retained in the medical record for audit support.

Compliance Risk: Specificity is key. Claims billed for non‑exudative or unspecified macular degeneration will be denied.

Pro Tip: OPT procedure must be billed on the same claim and date of service as the verteporfin drug.

9. Incident-to Supervision

Techs often perform testing; make sure the documentation supports the ordering provider’s involvement, supervision level, and interpretation/report where required—especially when billing “incident to.”

Pro Tip:  Review “Incident-to” guidelines to understand how the requirements apply to both ancillary staff as well as advance practice providers you may be working with.

Compliance Checklist

These compliance safeguards apply to all eye services:

Service: __________ (Code: _____)

  1. ☐ Coverage category confirmed (not routine/excluded)
  2. ☐ Medical necessity documented (dx supports service; record supports dx)
  3. ☐ LCD/NCD/manual followed (highlight requirement section)
  4. ☐ Interpretation & report present (where applicable)
  5. ☐ Modifier use justified and payer‑appropriate (laterality, -25, JW/JZ, etc.)
  6. ☐ NCCI checked (no incompatible code pairs)
  7. ☐ Inventory medication administration controls (if drugs involved)
  8. ☐ Texas Medicaid: TMPPM/Handbook checked (if applicable)

Final Thoughts

While eye care billing involves many moving parts, most compliance risk can be mitigated by consistently verifying coverage, clearly documenting medical necessity, and aligning documentation with applicable LCD, NCD, and payer‑specific requirements. Getting these fundamentals right protects patients, providers, and practices alike.
