Summary & Overview
CPT 0330T: Tear Film Thickness Imaging and Interpretation
Headline: New CPT code 0330T defines tear film thickness imaging and interpretation
Lead: CPT code 0330T designates a diagnostic imaging service in which a provider measures tear film thickness using a specialized imaging device, interprets the results, and provides a formal report. The code standardizes billing for a targeted ocular surface diagnostic procedure that supports assessment and management of tear film abnormalities.
What the code represents and why it matters: CPT code 0330T formalizes reimbursement and administrative handling for a specialized ocular surface imaging and interpretation service. Nationally, standardized coding for tear film measurement helps align clinical documentation, supports coverage decisions, and improves consistency in claims processing for eye-care diagnostic services.
Key payers covered: This analysis covers major national payers including Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare.
Overview of reader takeaways: Readers will gain a concise understanding of the clinical purpose of CPT code 0330T, typical sites of service, and which national payers are relevant to coverage considerations. The publication summarizes benchmarking and policy-relevant context where available, notes common billing modifiers provided in the input, and identifies areas where input data was not available for inclusion (for example, associated taxonomies and ICD-10 diagnoses).
Billing Code Overview
CPT code 0330T describes a diagnostic imaging assessment in which the provider measures tear film thickness using a specially designed imaging device, interprets the captured data, and issues a report of findings. This service is a diagnostic imaging and interpretation procedure focused on ocular surface evaluation.
Service type: Diagnostic imaging with professional interpretation and report
Typical site of service: Ophthalmology clinic, optometry clinic, or outpatient imaging center
Clinical & Coding Specifications
Clinical Context
A 62-year-old patient presents to an ophthalmology clinic with complaints of chronic ocular irritation, fluctuating vision and a foreign-body sensation consistent with suspected dry eye disease. The ophthalmologist orders a specialized noninvasive imaging test that measures tear film thickness and stability. The procedure is performed in an outpatient ophthalmology clinic or an ambulatory surgical center using a dedicated tear film imaging device. A certified ophthalmic technician or imaging technologist positions the patient, acquires images or scans of the tear film, and captures device output. The provider (ophthalmologist or optometrist with interpretation privileges) reviews the imaging data, assesses tear film thickness and maps focal deficiencies, interprets objective metrics (for example tear thickness, tear meniscus height, and spatial variability), documents findings in the medical record, and issues a formal report with diagnostic impressions and comparisons to prior studies if available. Results are used to guide management such as artificial tear selection, punctal occlusion consideration, environmental or medication adjustments, or referral for further corneal surface evaluation. Typical site of service: outpatient ophthalmology clinic, specialty eye imaging center, or ambulatory surgical center; imaging and technical acquisition occur in the clinic, interpretation and report generation are performed by the billing provider.
Coding Specifications

TC | Technical component | When billing only the technical component (device, technician acquisition) without provider interpretation |
52 | Reduced services | If the imaging study is partially performed or limited due to patient tolerance |
53 | Discontinued procedure | If the imaging was started but terminated for patient safety or compliance reasons |
59 | Distinct procedural service | Data not available in the input. |
62 | Two surgeons | When two surgeons of different specialties are involved in the interpretation or combined procedure |
78 | Return to OR for related procedure during postoperative period | When a related operative procedure is required after initial imaging and falls within the global period |
80 | Assistant surgeon | When an assistant surgeon performs allowable portions of the service under direct supervision |
82 | Assistant surgeon (when qualified resident not available) | When a qualified resident is not available and an assistant provides services |
QX | CRNA service with modifier QX | Data not available in the input. |
