Laser Iridotomy Cost, Insurance Coverage & What to Expect

Laser peripheral iridotomy (LPI, CPT 66761) is a standard office-based procedure for angle-closure glaucoma and narrow angles. Costs vary significantly by setting, geography, and insurance.

Typical Cost Ranges (2024 Estimates)

Setting	Total Cost (Uninsured/Cash)	Medicare Allowed (National Avg)
Ophthalmology Office	$800–$2,000	~$350–$450
Hospital Outpatient (HOPD)	$1,500–$4,000+	~$600–$900 (APC 5491)
Ambulatory Surgery Center (ASC)	$1,200–$3,000	~$500–$800

Note: Facility fees drive HOPD/ASC costs higher. Office-based LPI avoids facility fee.

Insurance Coverage

• Medically necessary LPI is covered by Medicare, Medicaid, and virtually all commercial plans for narrow angles, angle-closure, or prophylaxis in fellow eye.
• Patient cost-share: Deductible, copay ($20–$75 specialist), or coinsurance (10–20% of allowed amount).
• Prior authorization: Rarely required for LPI, but verify with plan.
• In-network vs. out-of-network: Out-of-network can mean balance billing (unless prohibited by state law).

What's Included in the Charge

• Professional fee (surgeon work)
• Facility fee (room, nursing, equipment, supplies) – if HOPD/ASC
• Pre-op evaluation (separate E/M visit if same day)
• Post-op drops (steroid, NSAID) – usually prescribed, not bundled
• Follow-up visits (typically 1-day, 1-week, 1-month – often global period 10–90 days)

Questions to Ask Before Scheduling

1. "What is the CPT code you'll bill?" (Confirm 66761)
2. "Is the procedure done in your office or a facility?"
3. "What is my estimated out-of-pocket based on my plan?"
4. "Are post-op drops and visits included in the global period?"
5. "Do you offer a cash-pay discount if I don't use insurance?"

Financial Assistance

Hospital-based programs: charity care, sliding scale. Pharmaceutical patient assistance for drops (e.g., Alcon, Allergan, Bausch + Lomb).

LPI is quick (5–10 min), low-risk, and highly effective—don't let cost uncertainty delay sight-saving treatment.
