⚕️CPT Code 92222: Fluorescein angiography (including multiframe imaging) with interpretation and report

Code Description

CPT 92222 describes the diagnostic procedure known as Fluorescein Angiography (FA). This code encompasses the injection of fluorescein dye (intravenous), the capture of multiframe images of the retina and choroid as the dye circulates, and the professional interpretation and report of the findings.

This procedure is critical for evaluating the vascular integrity of the retina and choroid. It is commonly used to diagnose and manage conditions such as diabetic retinopathy, age-related macular degeneration (AMD), retinal vein occlusions, and ocular tumors. The code includes both the technical component (imaging) and the professional component (interpretation) when performed globally.^{AMA CPT 2024}

Note: 92222 is a CPT procedure code. Metrics such as wRVU and Assistant Payable status apply to procedural coding. HCC risk adjustment applies only to diagnosis codes (ICD-10-CM).

Hierarchical Condition Category (HCC)

HCC Status: Not Applicable
Reasoning: HCC (Hierarchical Condition Category) models are used for risk adjustment based on patient diagnoses (ICD-10-CM), not procedures.
Related Diagnosis Impact: While the procedure itself does not generate HCC risk, the underlying diagnosis driving the necessity of 92222 (e.g., E11.319 Type 2 diabetes with diabetic retinopathy) carries significant HCC weight for Medicare Advantage risk adjustment. Accurate linkage of the procedure to the chronic condition is vital for risk profiling.^{CMS HCC Model Documentation}

Financial & Billing Metrics

Metric	Value	Notes
wRVU	1.06	Work Relative Value Unit (2024 Medicare Physician Fee Schedule Non-Facility). Facility wRVU is typically lower (0.37).
Total RVU (Non-Fac)	1.99	Includes Work, Practice Expense, and Malpractice components in office setting.
Total RVU (Fac)	0.79	Includes Work, Practice Expense, and Malpractice components in facility setting.
Assistant Payable	No	Assistant at Surgery Indicator: 2 (Payment not allowed for assistant surgeon).
Global Period	0 Days	Diagnostic procedure; no post-operative period. E/M services may be billed separately if significant (Modifier 25).
Facility Pricing	Yes	Performed in Hospital Outpatient Departments (HOPD) and ASCs.
Non-Facility Pricing	Yes	Commonly performed in office-based imaging suites.

Official Coding Guidelines

Includes

Intravenous injection of fluorescein dye.
Multiframe imaging (serial photography) of the retina/choroid.
Interpretation of the angiographic findings.
Written report generated by the physician.
Unilateral or bilateral (see modifiers).

Excludes / Parenthetical Notes

Indocyanine Green (ICG): If ICG angiography is performed, report 92227 instead of or in addition to 92222 (if both are medically necessary and distinct).
Optical Coherence Tomography (OCT): Do not report 92228 (OCT) with 92222 unless performed on different dates or distinct clinical indications supported by documentation.
External Photography: 92285 (External ocular photography) is generally bundled or distinct depending on payer policy; often not billed with FA for the same session.
Remote Imaging: 92229 (Imaging for detection/monitoring) is distinct from FA.^{AMA CPT 2024}

Modifiers

-26: Professional Component (If only the interpretation is performed, e.g., images taken elsewhere).
-TC: Technical Component (If only the imaging is performed, e.g., technician captures images, physician interprets later).
-50: Bilateral Procedure (If performed on both eyes during the same session).
-RT / -LT: Right Eye / Left Eye (Required by most payers if not using -50).
-59: Distinct Procedural Service (If performed with another unrelated procedure on the same day).
-25: Significant, Separately Identifiable Evaluation and Management Service (If an E/M visit occurs on the same day as the FA).

MS-DRG and APC Assignment

MS-DRG (Inpatient): Not Applicable
- Reasoning: MS-DRGs are assigned based on ICD-10-PCS procedure codes for inpatient hospital stays. 92222 is a CPT code used for physician/outpatient billing.
- Inpatient Equivalent: If performed inpatient, hospital coding will use ICD-10-PCS (e.g., Nuclear Medicine Imaging of Eye).
APC (Outpatient): Applicable
- System: Ambulatory Payment Classification (APC) under the Hospital Outpatient Prospective Payment System (OPPS).
- Status Indicator: Typically Status Indicator S (Significant Procedure, not reduced when multiple) or Q2/Q3 depending on specific year packaging rules.
- Associated APC: Often maps to APC 5503 (Level 3 Minor Procedures) or specific Imaging APCs depending on the current year’s OPPS final rule.^{CMS OPPS Final Rule}

Code Tree (Hierarchy)

The following hierarchy illustrates the placement of 92222 within the CPT structure:

Section: Medicine
- Subsection: Ophthalmology
  - Category: Diagnostic Imaging
    - Subcategory: Angiography
      - Code: 92222 (Fluorescein angiography)
      - Code: 92227 (Indocyanine green angiography)

Coding Examples

Example 1: Diabetic Retinopathy Evaluation

Scenario: A patient with Type 2 Diabetes presents for worsening vision. The physician suspects diabetic macular edema. Fluorescein angiography is performed on both eyes to assess leakage.
CPT Code: 92222-50
ICD-10-CM: E11.319 (Type 2 diabetes mellitus with unspecified diabetic retinopathy with macular edema)
Rationale: Bilateral procedure requires modifier 50. The diagnosis supports medical necessity.^{AAO Coding Expert}

Example 2: Professional Component Only

Scenario: A patient undergoes fluorescein angiography at a hospital outpatient department. The images are sent to the private ophthalmologist for interpretation and report only.
CPT Code: 92222-26
ICD-10-CM: H35.352 (Cystoid macular degeneration, left eye)
Rationale: Modifier 26 indicates only the professional component (interpretation) is being billed by the physician.^{AAO Coding Expert}

Example 3: Exclusion Scenario (OCT Same Day)

Scenario: The physician performs FA and OCT on the same day for the same condition (AMD).
CPT Code: 92222 and 92228 (With Modifier 59 if payer requires distinct separation).
ICD-10-CM: H35.30 (Unspecified macular degeneration)
Rationale: While often performed together, some payers bundle OCT with FA. Documentation must support the medical necessity of both distinct diagnostic tests. Modifier 59 may be needed to bypass NCCI edits.^{CMS NCCI Policy Manual}

Clinical Documentation Improvement (CDI) Tips

Medical Necessity: Document the specific clinical question being answered by the FA (e.g., “rule out choroidal neovascularization,” “assess leakage”).
Interpretation: A separate, signed report detailing the findings (e.g., transit times, leakage areas, ischemia) is required to bill 92222. The images alone are insufficient.
Laterality: Clearly specify which eye(s) were imaged. If bilateral, ensure modifier -50 is applied correctly according to payer preference (some prefer -RT/-LT on two lines).
Dye Administration: Document the type and amount of dye used, and any adverse reactions, to support the technical component.^{AAO Coding Expert}

92227: Indocyanine green angiography (ICG)
92228: Optical coherence tomography (OCT)
92229: Imaging for detection/monitoring of retinal disease
