Key Modifiers
- -RT / -LT: Right or Left Eye (Vital for laterality)

📖 Specialty Etymology
| Term | Etymology | Breakdown |
|---|---|---|
| Aphakia | Gr. a- (without) + phakos (lens) | Condition of being without a lens. |
| blepharitis | Gr. blepharon (eyelid) + -itis (inflammation) | Inflammation of the eyelids. |
| Glaucoma | Gr. glaukos (silver/gray) + -oma (mass/condition) | Named for the hazy/gray appearance of the eye in advanced stages. |
| Presbyopia | Gr. presbys (old man) + ops- (eye) | Age-related vision loss (farsightedness). |
Coding Tip
Always check if the physician documented the “Eye Code” (920xx) vs. the “E/M Code” (992xx). Use the one that provides the most appropriate reimbursement based on the level of exam performed.
Retina Surgery & Vitrectomy
Complex vs. Simple Repair
- 67113 (Complex Repair): Requires specific pathology. Documentation must explicitly state one of the following to justify “complex”:
- Proliferative vitreoretinopathy (PVR) grade C-1 or greater.
- Diabetic traction retinal detachment.
- Retinopathy of prematurity.
- Giant retinal tear (>90 degrees).
- Mandatory Elements for 67113: Must perform Vitrectomy AND Membrane Peeling. If peeling is not done, you cannot use 67113.
Bundling Alerts (NCCI)
- Lensectomy (66850) with Vitrectomy (67036): Generally bundled.
- Rule: You cannot bill 66850 separately unless the lens is removed and an IOL is NOT inserted (left aphakic).
- Exception: If the code descriptor includes “removal of lens” (e.g., 67113), you never bill lensectomy separately.
- Air/Gas/Oil: Tamponade is included in the main vitrectomy codes (67042, 67108, 67113) and is not separately billable.
New Technology (2025)
- [[0936T]]: New Category III code for Photobiomodulation therapy of the retina (single session). Use Modifier 50 for bilateral.
- Subretinal Gene Therapy: HCPCS C9770 covers vitrectomy with subretinal injection (e.g., Luxturna administration). Do not bill standard vitrectomy (67036) for this.
Diagnostic Imaging Rules
B-Scan Ultrasound (76512 vs. 76513)
- 76512 (Posterior): Use for structures behind the lens (e.g., Retinal Detachment, vitreous hemorrhage, optic nerve head).
- 76513 (Anterior): Use for structures at or in front of the lens (e.g., IOL position, iris cysts, ciliary body, UBM for glaucoma).
OCT & Fundus Photos
- Bundling: NCCI generally prohibits billing Fundus Photos (92250) and OCT Retina (92134) on the same day for the same eye.
- Exceptions: You may be able to bill both if they are for distinct diseases (e.g., OCT for AMD, Photos for a nevus). Documentation must clearly link the specific diagnosis to each test.
- OCT Angiography (92137): Do not report with standard OCT (92133/92134) on the same day.
Visual Fields (9208x)
- Gross vs. Formal: Confrontation fields are part of the exam (E/M or Eye Code). Only formal automated perimetry is billable separately.
- Medical Necessity: Often denied for “routine” screening. Must have a specific indication (e.g., Glaucoma suspect, high-risk meds like Plaquenil, eyelid ptosis with functional limitation).
- Systemic Links: If testing for medication toxicity (Plaquenil), link the Z-code for long-term drug use to the CPT, not just the visual symptom.
