Summary: The Centers for Medicare & Medicaid Services modified its coverage policy on the use of visual tests and general anesthesia during cataract surgery, effective May 15, 2026. Here's what billing teams need to do.
CMS cataract surgery coverage policy has been a consistent source of claim denial risk for ophthalmology and anesthesia billing teams. This modification addresses two specific areas: pre-operative visual testing billed alongside cataract procedures, and the use of general anesthesia when local or monitored anesthesia care would typically suffice. The policy does not list specific CPT or HCPCS codes in the source data available at publication time. Check the full policy at the CMS source link and confirm current code-level guidance with your Medicare Administrative Contractor before May 15, 2026.

CMS Cataract Surgery Coverage Criteria and Medical Necessity Requirements 2026
The CMS cataract surgery coverage policy governs two distinct billing situations that frequently generate scrutiny: visual tests performed before the procedure and general anesthesia used during it. Both have specific medical necessity thresholds that, when not met with solid documentation, produce denials.
On the visual testing side, CMS has long held that certain pre-operative tests are bundled into the global cataract surgery period. The real issue is when separate billing for those tests is appropriate. A test ordered for an independent clinical purpose — one not directly tied to the surgical planning — can be billed separately. A test performed solely to prepare for or manage the surgical episode is bundled, period.
The general anesthesia question is more nuanced. Medicare's default for cataract surgery is topical, local, or regional anesthesia, sometimes paired with monitored anesthesia care (MAC). General anesthesia is considered medically necessary only when a specific documented clinical reason makes the standard approach unsafe or unworkable. Without that documentation, general anesthesia reimbursement is at risk.
Prior authorization is not typically required for routine Medicare cataract surgery, but that does not protect you from post-payment review. Medical necessity documentation is your defense. If your anesthesia team bills for general anesthesia without a clear clinical rationale in the record, expect audit exposure.
CMS Pre-Operative Visual Testing and Anesthesia: What Is Not Covered
CMS does not cover pre-operative visual tests when they are performed as routine pre-surgical workup without an independent clinical indication. If the only reason the test was ordered is that a cataract surgery is scheduled, it is bundled.
Similarly, general anesthesia for cataract surgery is not covered as a routine choice. The surgeon or anesthesiologist cannot simply prefer general anesthesia or document patient preference as the justification. CMS requires a clinical reason — a specific condition that makes local or regional anesthesia contraindicated or unsafe.
Common scenarios that do not support separate reimbursement for general anesthesia include patient anxiety alone, general preference for being "asleep," or surgeon convenience. These are the situations your documentation review should catch before claims go out.
Coverage Indications at a Glance
| Indication | Status | Relevant Codes | Notes |
|---|---|---|---|
| Pre-operative visual test with independent clinical indication | Covered | Policy does not list specific codes | Must document that the test was ordered for a reason separate from surgical planning |
| Pre-operative visual test performed solely for surgical preparation | Not Covered (Bundled) | Policy does not list specific codes | Considered part of the global cataract surgery package |
| General anesthesia with documented clinical contraindication to local/regional anesthesia | Covered | Policy does not list specific codes | Requires specific clinical rationale in the operative and anesthesia record |
| General anesthesia as routine choice without clinical contraindication | Not Covered | Policy does not list specific codes | Patient preference or surgeon convenience alone does not meet medical necessity |
| Monitored anesthesia care (MAC) during cataract surgery | Covered (standard) | Policy does not list specific codes | Standard anesthesia approach for Medicare cataract patients |
CMS Cataract Surgery Billing Guidelines and Action Items 2026
This is where the rubber meets the road. The effective date of May 15, 2026 gives your team a hard deadline. Work backwards from it.
| # | Action Item |
|---|---|
| 1 | Audit your pre-operative visual testing claims now. Pull cataract surgery claims from the last 12 months. Identify every pre-op visual test billed on or near the surgical date. Confirm each one has a documented independent clinical indication. If the record only references surgical planning, you have a vulnerability. |
| 2 | Review your anesthesia documentation protocol with your anesthesiology group. Before May 15, 2026, your anesthesia providers should be documenting the specific clinical reason for general anesthesia when MAC or local is the CMS default. A generic "patient requested" or "surgeon preference" note will not survive audit. |
| 3 | Check with your Medicare Administrative Contractor. This policy may be implemented through local coverage determination at the MAC level. Your MAC may have specific LCD guidance that supplements the CMS position. Contact your MAC or check their website for any LCD tied to cataract surgery visual testing and anesthesia. |
| 4 | Update your charge capture workflow for pre-op testing. Add a documentation checkpoint before pre-op visual tests are captured for billing. Your billing team should not release those charges without confirmation that the ordering provider documented an independent clinical reason. Build this into your workflow before May 15, 2026. |
| 5 | Brief your surgical coordinators and pre-op nursing staff. They often initiate the orders for pre-op testing. They need to understand that "cataract surgery scheduled" is not a sufficient clinical indication for separate billing. The documentation has to reflect why that specific test was needed for that specific patient. |
| 6 | Pull your general anesthesia cases for cataract surgery and flag any without documented contraindications. If your ASC or hospital outpatient department has been billing general anesthesia for cataract cases without a clear documented clinical reason, that exposure does not disappear after May 15 — it also applies to open claims and audit lookback periods. |
| 7 | Talk to your compliance officer if your volume is high. Cataract surgery is one of the highest-volume Medicare procedures in ophthalmology. If your practice or facility does significant cataract volume, the financial exposure from improper pre-op testing or anesthesia billing is real. If you are unsure how this policy applies to your specific billing mix, loop in your compliance officer before the effective date. |

CPT, HCPCS, and ICD-10 Codes for Cataract Surgery Visual Testing and Anesthesia Under This Policy
The policy source data does not list specific CPT, HCPCS, or ICD-10 codes. This is a gap worth flagging.
For cataract surgery billing, your team likely works with codes across several families — cataract extraction and lens insertion codes, pre-operative ophthalmologic testing codes, and anesthesia codes tied to the ocular surgery time-based billing. The policy's silence on specific codes does not mean the codes are unaffected. It means CMS is applying this coverage policy as a medical necessity and bundling rule, not a code-specific edit.
What to Do Without a Code List
Contact your MAC directly and ask for any associated LCD or billing article that lists the specific codes subject to these bundling and medical necessity rules. MACs often publish billing articles alongside national policies that give you the code-level detail CMS doesn't include at the national level.
Your ophthalmology-specific billing guidelines from your professional association (such as the American Academy of Ophthalmology) will also have crosswalks between the policy's clinical language and the CPT codes your team actually bills.
Do not assume that because CMS did not publish a code table with this policy, no codes are at risk. The bundling and medical necessity standards apply to the claims regardless.
A Note on Anesthesia Billing
Cataract surgery anesthesia billing follows the standard anesthesia time-unit model. If your anesthesia team bills general anesthesia using a code that implies a higher-complexity anesthetic service, and the documentation does not support medical necessity for that service level, the claim denial risk is real — both at the initial claim level and on audit.
