Summary & Overview
CPT 0606T: Remote OCT Retinal Image Review and Interpretation, 30-Day
CPT code 0606T represents a 30‑day interval service: the provider’s review, interpretation, and reporting of patient‑initiated remote optical coherence tomography (OCT) retinal images. As remote retinal imaging and tele‑ophthalmology expand, this code standardizes billing for periodic professional interpretation tied to patient‑initiated submissions. Nationally, adoption affects both outpatient ophthalmology practices and telehealth services that manage chronic retinal conditions.
Key payers addressed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Coverage policies and payment rates for this CPT code influence clinical workflows, remote monitoring programs, and vendor-supported imaging platforms.
Readers will learn what the code covers, the typical service and site of service, and which major payers are relevant to coverage discussions. The publication provides benchmarks for how the code is used, summarizes recent policy updates where available, and places the code in clinical context for remote retinal monitoring programs. Data not available in the input for associated taxonomies, ICD‑10 diagnoses, and specific related codes are noted where applicable.
Billing Code Overview
CPT code 0606T is reported for each 30‑day period when a provider reviews and interprets patient‑initiated, remote optical coherence tomography (OCT) retinal images and prepares a report. This code covers the professional interpretation and reporting of remotely transmitted OCT retinal imaging initiated by the patient.
-
Service type: Remote image review and interpretation of OCT retinal images, patient‑initiated
-
Typical site of service: Remote/telehealth‑enabled review (provider office or remote work setting receiving patient‑initiated images)

Clinical & Coding Specifications
Clinical Context
A 68-year-old patient with known neovascular age-related macular degeneration (AMD) at home uses a patient-operated, remote optical coherence tomography (OCT) device to capture retinal scans weekly. Images are transmitted electronically to the treating ophthalmologist. Once every 30-day period the clinician reviews the patient-initiated OCT images, interprets retinal fluid or neovascular activity, documents findings and treatment recommendations in the chart, and prepares a formal report for the referring provider and the patient. Typical workflow steps include image receipt and quality check by clinic staff, clinician review and comparison to prior imaging, documentation of interpretation and management plan, and secure transmission of the report to the patient and referring clinician. Typical site of service is an outpatient ophthalmology clinic, telehealth/remote monitoring service, or hospital outpatient department depending on provider setting. Common scenarios include monitoring response to intravitreal injection therapy, early detection of recurrence in previously treated AMD, and surveillance of diabetic macular edema in patients with barriers to frequent in-person visits.
Coding Specifications
| Modifier | Description | When to Use |
|---|---|---|
22 | Increased procedural service | Use when the interpretation and report required substantially greater work or complexity than typical for the 30‑day review period. |
23 | Unusual anesthesia | Rarely applicable; use only if unrelated anesthesia was required during imaging capture and documentation meets criteria. |
52 | Reduced services | Use when the clinician provides a reduced intensity of review/report compared with full service for the 30‑day period. |
53 | Discontinued procedure | Use if the remote monitoring review process was started but discontinued due to patient factors before a complete interpretation/report could be produced. |
54 | Surgical care only | Not typically applicable; use if another clinician provides the interpretation/report separate from surgical care responsibilities. |
55 | Postoperative management only | Use if the reviewer is only providing postoperative remote OCT monitoring and not initial surgical care. |
56 | Preoperative management only | Use if the clinician only provided preoperative remote OCT interpretation separate from intraoperative care. |
62 | Two surgeons | Use when two surgeons of different specialties are required to provide the interpretation/report and both meet documentation requirements. |
AS | Ambulatory surgical center | Use when the billing is associated with services performed under the facility taxonomy of an ambulatory surgical center. |
CQ | Service furnished using communication technology | Use to indicate remote patient monitoring/interpretation performed using asynchronous telehealth/remote imaging technology when applicable. |
QK | Medical direction of certified registered nurse anesthetist (CRNA) | Not typically applicable; include only in rare scenarios involving CRNA direction during related procedures. |
QX | CRNA service with medical direction | Not typically applicable; include only if CRNA is involved and meets coding criteria. |
QY | Medical direction of one CRNA by an anesthesiologist | Not typically applicable to remote OCT review. |
SH | Assistant at surgery, hospital setting | Rarely applicable; use only if an assistant performed tasks directly related to the interpretation workflow in the hospital. |
| Taxonomy Code | Specialty | Notes |
|---|---|---|
207W00000X | Ophthalmology | Most common specialty performing remote OCT interpretation and reporting. |
207K00000X | Retina Specialist (Ophthalmology) | Retina subspecialists frequently interpret OCT for AMD and diabetic macular edema. |
363L00000X | Telehealth Services | Providers specializing in telehealth-based remote image interpretation and monitoring. |
207P00000X | Optometry | In some practices optometrists may review images and prepare reports under scope of practice and local regulations. |
