TL;DR: The Centers for Medicare & Medicaid Services modified NCD 56 governing intraocular photography coverage, effective January 9, 2026. This policy does not list specific CPT codes, so your billing team needs to apply medical necessity criteria manually for each claim.
CMS updated the intraocular photography coverage policy under NCD 56, clarifying the diagnostic indications that qualify for Medicare reimbursement under Physicians' Services. The policy specifies covered conditions including macular degeneration, retinal neoplasms, choroid disturbances, diabetic retinopathy, glaucoma, multiple sclerosis, and other central nervous system abnormalities. No specific CPT or HCPCS codes are listed in this National Coverage Determination, which creates documentation and claim submission challenges your billing team should address now.

CMS Intraocular Photography Coverage Criteria and Medical Necessity Requirements 2026
NCD 56 is the National Coverage Determination governing Medicare coverage of intraocular photography under the Physicians' Services benefit category. The Centers for Medicare & Medicaid Services will pay for this procedure when an ophthalmologist uses it to diagnose or identify specific conditions — and only when it is "reasonable and necessary" for the individual patient.
That "reasonable and necessary" standard is the one you need to build your documentation around. CMS does not cover intraocular photography as a routine screening tool. It covers it as a diagnostic procedure tied to specific clinical indications.
What Qualifies as Medically Necessary Under NCD 56
The CMS intraocular photography coverage policy identifies the following diagnostic uses as covered:
| # | Covered Indication |
|---|---|
| 1 | Macular degeneration — documentation and diagnosis |
| 2 | Retinal neoplasms — identifying and characterizing neoplastic changes |
| 3 | Choroid disturbances — any choroidal pathology requiring photographic documentation |
| 4 | Diabetic retinopathy — staging and monitoring retinal changes from diabetes |
| 5 | Glaucoma — identifying optic nerve and retinal changes associated with glaucoma |
| 6 | Multiple sclerosis — identifying central nervous system abnormalities with ocular manifestations |
| 7 | Other central nervous system abnormalities — a catch-all that requires strong clinical justification in the medical record |
That last category is where claims go sideways. "Other CNS abnormalities" is broad, and CMS auditors will want to see documented clinical rationale explaining why intraocular photography was medically necessary for that specific patient. Document it clearly before you bill.
Prior Authorization and Billing Guidelines
The NCD 56 policy does not specify a prior authorization requirement at the national level. That said, your Medicare Administrative Contractor may have issued a Local Coverage Determination that adds prior auth requirements or tightens the covered indication list. Check with your MAC before assuming national NCD 56 coverage translates directly to your region.
The policy restricts payment to procedures performed by an ophthalmologist. If your practice has other providers performing intraocular photography — optometrists or technicians billing incident-to — review whether those claims meet the ophthalmologist-performer requirement under this coverage policy. If you're unsure how that applies to your specific billing setup, loop in your compliance officer before the January 9, 2026 effective date.
The "Reasonable and Necessary" Standard in Practice
CMS uses "reasonable and necessary" as a two-part test. The procedure must be appropriate for the diagnosis, and it must be appropriate for this patient at this time. That means a blanket order for intraocular photography on every diabetic patient doesn't automatically clear medical necessity. The documentation needs to show that this patient, at this visit, needed the imaging to guide clinical decision-making.
Train your clinical documentation staff on this distinction. A missing or vague diagnosis note is the fastest route to a claim denial under NCD 56.
Coverage Indications at a Glance
| Indication | Status | Relevant Codes | Notes |
|---|---|---|---|
| Macular degeneration | Covered | No specific codes listed in NCD 56 | Requires documented medical necessity for individual patient |
| Retinal neoplasms | Covered | No specific codes listed in NCD 56 | Ophthalmologist must perform procedure |
| Choroid disturbances | Covered | No specific codes listed in NCD 56 | Document specific choroidal pathology in the medical record |
| Diabetic retinopathy | Covered | No specific codes listed in NCD 56 | Staging and monitoring use both qualify; document clearly |
| Glaucoma | Covered | No specific codes listed in NCD 56 | Link photography to optic nerve or retinal assessment |
| Multiple sclerosis | Covered | No specific codes listed in NCD 56 | CNS indication — requires strong clinical documentation |
| Other CNS abnormalities | Covered (with justification) | No specific codes listed in NCD 56 | High audit risk; document clinical rationale explicitly |
| Routine screening (no diagnosis) | Not Covered | N/A | No covered indication without a qualifying diagnosis |
CMS Intraocular Photography Billing Guidelines and Action Items 2026
The absence of specific CPT or HCPCS codes in NCD 56 is the real operational challenge here. You can't just build a crosswalk table and call it done. Your team needs to know which codes you're currently using for intraocular photography and confirm each one is defensible under NCD 56's indications list.
| # | Action Item |
|---|---|
| 1 | Audit your intraocular photography charge capture now. Pull claims from the past 12 months where your practice billed for intraocular photography under Medicare. Identify every CPT or HCPCS code your team used. Confirm each claim had a covered diagnosis attached from the NCD 56 indications list. Do this before January 9, 2026. |
| 2 | Check your MAC for a Local Coverage Determination. NCD 56 sets national coverage rules, but your Medicare Administrative Contractor may have issued an LCD that adds criteria, restricts indications, or specifies covered codes. Search your MAC's LCD database for intraocular photography policies and reconcile any differences with your current billing guidelines. |
| 3 | Verify the ophthalmologist-performer requirement. The policy explicitly requires an ophthalmologist to perform the procedure. If your practice bills intraocular photography performed by other staff, review every claim type for compliance with this requirement. An incident-to claim that doesn't meet this standard is a claim denial waiting to happen. |
| 4 | Tighten your documentation templates. Every intraocular photography order and encounter note should explicitly tie the imaging to one of the covered indications. Generic notes like "retinal exam" aren't enough. Document the specific condition — macular degeneration, diabetic retinopathy, suspected CNS abnormality — and why photography was necessary for this patient at this encounter. |
| 5 | Flag "other CNS abnormalities" claims for secondary review. This is the highest-risk covered indication. Claims under this catch-all category invite scrutiny. Build a secondary review step into your workflow for any intraocular photography claim tied to CNS indications outside of multiple sclerosis. Your medical director should sign off on the clinical justification before these go to billing. |
| 6 | Confirm reimbursement rates with your MAC. NCD 56 doesn't address the fee schedule. CMS reimbursement for intraocular photography depends on the specific CPT code your practice uses and the Medicare Physician Fee Schedule rates for your locality. If you haven't confirmed current rates with your MAC, do it now. |
| Previous Version | Current Version |
|---|---|
| Coverage is considered experimental and investigational for all indications | Coverage is considered medically necessary when specific criteria are met |
| Prior authorization is not required | Prior authorization is required for initial treatment |
| Documentation must include clinical history | Documentation must include clinical history |
| Re-review every 24 months | Re-review every 12 months with updated clinical documentation |
CPT, HCPCS, and ICD-10 Codes for Intraocular Photography Under NCD 56
NCD 56 does not list specific CPT, HCPCS, or ICD-10 codes. This is unusual for a National Coverage Determination and creates real billing guidelines challenges for ophthalmology practices.
Because no codes are specified in the policy, your team must:
- Identify the CPT codes your practice currently uses for intraocular photography
- Confirm those codes map accurately to the diagnostic indications listed in NCD 56
- Check your MAC's LCD and coverage articles for any code-specific guidance
The table below reflects what the policy documents.
Covered CPT Codes (When Medical Necessity Criteria Are Met)
| Code | Type | Description |
|---|---|---|
| Not specified in NCD 56 | — | CMS does not enumerate CPT or HCPCS codes in this NCD. Contact your MAC for code-specific guidance. |
Key ICD-10-CM Diagnosis Codes
The NCD 56 policy does not list ICD-10-CM codes. The covered diagnostic indications described in the policy map to ICD-10 categories your coding team should identify. Those indications include macular degeneration, retinal neoplasms, choroid disturbances, diabetic retinopathy, glaucoma, multiple sclerosis, and other CNS abnormalities. Work with your coding team to build a crosswalk between those conditions and your active ICD-10-CM codes.
If you're not sure which codes your practice should be using for intraocular photography billing under NCD 56 — and that answer isn't obvious given the absence of code-level guidance in the NCD — talk to your billing consultant or compliance officer before submitting claims under this modified policy.
