Crystal's Coder Hub👁️ CPT 92202 — Ophthalmoscopy, Extended; With Drawing of Optic Nerve or Macula, With Interpretation and Report, Unilateral or Bilateral
“Ophthalmoscopy, extended; with drawing of optic nerve or macula (eg, for glaucoma, macular pathology, tumor) with interpretation and report, unilateral or bilateral”
Quick Reference
wRVU: 0.53 | Global Period: 000 | Assistant Payable: No | Bilateral Indicator: 2
Rule: Bilateral indicator 2 means the fee schedule rate already reflects unilateral or bilateral performance — do not append modifiers -50, -RT, or -LT. The global period of 000 means only the day of service is bundled; no pre-op or post-op period applies. CPT 92202 replaced the deleted codes 92225 and 92226 effective January 1, 2018 — those legacy codes are no longer valid. Unlike 92201, CPT 92202 does not require scleral depression; it focuses on the posterior pole (optic nerve head and macula) rather than the peripheral retina, and it is the appropriate extended ophthalmoscopy code for glaucoma and macular pathology encounters.12
📋 Clinical Description
CPT 92202 describes an extended ophthalmoscopy focused on the posterior pole — specifically the optic nerve head and/or the macula — performed with a high-powered condensing lens (typically a 90D or 78D lens at the slit lamp, or a 20D lens with BIO for stereoscopic posterior pole assessment), resulting in a detailed, labeled drawing of the optic nerve or macula and a written interpretation and report.1 This is fundamentally different from 92201, which is reserved for scleral-depression-based peripheral retinal examination: 92202 targets the structures most critical to glaucoma monitoring (optic nerve head morphology, cup-to-disc ratio, neuroretinal rim contour, disc hemorrhages) and macular disease surveillance (drusen, geographic atrophy, choroidal neovascular membrane borders, pigment epithelial detachments).2 The required drawing must be a labeled, individualized anatomical schematic — not a generic template — documenting the specific findings observed in the patient’s optic nerve or macula on that date of service, allowing meaningful comparison across visits.3
The code applies equally to glaucoma monitoring and macular pathology evaluation, as long as the documented service includes an extended examination beyond routine ophthalmoscopy, a qualifying labeled drawing, and a separate written interpretation and report.4 In a busy glaucoma practice, 92202 is one of the most valuable and frequently under-billed codes: many physicians perform this level of service at every glaucoma monitoring visit by carefully drawing the optic nerve, documenting cup-to-disc ratio changes, and charting disc hemorrhages — yet fail to generate the formally required separate interpretation and report that makes the claim defensible at audit.2
This procedure may be performed in the following clinical contexts:
- Glaucoma progression monitoring — An established glaucoma patient presents for a monitoring visit; the physician performs meticulous stereoscopic optic nerve evaluation at the slit lamp with a 90D lens, documents cup-to-disc ratio, neuroretinal rim thinning at specific clock hours, and any new disc hemorrhages on a labeled optic nerve drawing, with a separate signed interpretation comparing findings to prior drawings.1
- Suspected glaucomatous optic neuropathy — A patient with elevated IOP, suspicious optic nerves, and borderline visual fields undergoes 92202 for detailed optic nerve head documentation to establish a structural baseline before initiating treatment.
- Neovascular AMD surveillance and mapping — In a patient with known exudative age-related macular degeneration receiving anti-VEGF injections, the extended macular examination documents the size and borders of the choroidal neovascular membrane, subretinal fluid extent, and pigment epithelial detachment morphology on a labeled macular drawing.3
- Posterior pole tumor characterization — A patient with a suspected choroidal melanoma or metastatic lesion at the posterior pole undergoes 92202 for detailed drawing and measurement documentation of lesion characteristics (height estimation, pigmentation, overlying subretinal fluid) to guide referral and biopsy decisions.
- Optic nerve head drusen evaluation — Extended ophthalmoscopy with a detailed optic nerve drawing documents the location and extent of optic disc drusen, distinguishing buried from superficial drusen and monitoring for associated complications such as peripapillary choroidal neovascularization.4
🔬 Anatomical & Procedural Considerations
| Variant | Mechanism | Key Notes |
|---|---|---|
| Slit Lamp Biomicroscopy with 90D or 78D Lens (Posterior Pole Focus) | A high-powered non-contact condensing lens held in front of the dilated pupil at the slit lamp converts the diverging rays into an inverted aerial image of the posterior pole. The 90D lens provides a wide field (approximately 80° diameter) covering both the optic nerve and macula simultaneously with excellent stereopsis. The 78D lens offers higher magnification with a slightly narrower field. The physician controls the slit beam angle and width to examine the neuroretinal rim in fine detail, identify hemorrhages, and assess cup morphology. | This is the most commonly used technique for 92202 in glaucoma practices. Pharmacologic dilation is preferred but not always required for posterior pole assessment with a 90D lens. The drawing created using this technique typically features both the optic nerve and fovea on a standardized posterior pole diagram with labeled clock-hour positions. Documentation must confirm the lens used, the dilation status, and that a labeled drawing was produced with a separate written interpretation.13 |
| Binocular Indirect Ophthalmoscopy (BIO) with 20D Lens for Posterior Pole | BIO can also be used to evaluate the posterior pole when a wider field survey is needed — for example, when assessing the relationship between a posterior pole tumor and the optic nerve and macula simultaneously. The 20D lens provides a 60°-65° field with moderate stereopsis. | BIO is less commonly used for isolated posterior pole evaluation compared to slit lamp biomicroscopy, but it is a valid technique for 92202 when documented. The key distinction from 92201 is that no scleral depression is performed — the examination targets the posterior segment structures visible without peripheral indentation. All other documentation requirements (labeled drawing, written interpretation, report) are identical to 92201.2 |
| Contact Lens Biomicroscopy (Goldmann 3-Mirror, Posterior Pole Lens) | A fundus contact lens applied with coupling gel to the anesthetized cornea provides the highest magnification and stereopsis for optic nerve and macular detail. The central mirror of the Goldmann 3-mirror lens covers the posterior pole; dedicated contact lenses like the Volk Area Centralis are optimized for macular imaging. | Contact lens biomicroscopy is the gold standard for evaluating fine macular structural detail (e.g., subtle epiretinal membrane contraction, lamellar macular holes, vitreoretinal traction patterns) that may not be captured adequately with a non-contact 90D lens approach. Document the specific lens used and that the examination produced findings sufficient to generate a labeled, individualized macular or optic nerve drawing.4 |
Clinical Pearl
The single most important documentation distinction between CPT 92202 and routine posterior segment examination bundled into a standard eye exam (92002–92014) is the labeled, individualized drawing and separate written interpretation and report.3 A glaucoma monitoring note that says “C/D 0.7 OU, stable” does not qualify for 92202 — but a note that includes a hand-drawn or EHR-generated labeled optic nerve schematic with clock-hour neuroretinal rim detail, documented disc hemorrhage location, and a separate signed physician interpretation analyzing progression compared to prior drawings does qualify. The drawing plus the report are the clinical and billing foundation of this code.2
✅ Procedure Includes
- Extended slit lamp or indirect ophthalmoscopic examination of the optic nerve head or macula — The complete posterior pole evaluation targeting the optic disc and/or macula beyond routine ophthalmoscopy is bundled; no separate exam component is billable alongside this service.1
- Pharmacologic mydriasis when required — Topical mydriatic agents used to dilate the pupil for adequate posterior pole visualization are integral to the procedure and are not separately reportable.
- Labeled drawing of the optic nerve or macula — The individualized, anatomically labeled schematic documenting the findings is a required, non-separately-billable component of the 92202 service.2
- Written physician interpretation and report — The formal signed written analysis comparing current findings to prior examinations, documenting progression or stability, and outlining clinical implications is a bundled, required deliverable of 92202.3
- Examination of both eyes when clinically indicated — CPT 92202 is reported once per encounter regardless of whether one or both eyes are examined; bilateral examination does not generate a second unit of service.4
- Contact lens application (when used) — Instillation of topical anesthetic and application of coupling gel for contact lens biomicroscopy, when used as the examination technique, is considered integral to the procedure.
❌ Excludes / Do Not Report Together
| Code | Description | Relationship |
|---|---|---|
| 92201 | Ophthalmoscopy, extended; with retinal drawing and scleral depression of peripheral retinal disease, with interpretation and report, unilateral or bilateral | 92201 and 92202 are mutually exclusive under NCCI — they cannot be reported together on the same date of service. If both a peripheral retinal lesion (requiring 92201) and an optic nerve or macular lesion (requiring 92202) are evaluated on the same day, only one extended ophthalmoscopy code may be reported. Select the code that reflects the primary clinical service performed. Modifier -59 will not override this NCCI bundle.23 |
| 92250 | Fundus photography with interpretation and report | CPT 92202 and 92250 are bundled under NCCI and cannot be reported together on the same date of service. The NCCI bundle between these two codes has a bundling indicator of 0, meaning they cannot be unbundled with any modifier. Do not add fundus photography to a 92202 claim on the same day.2 |
| 92004 | Ophthalmological services, new patient, comprehensive | Routine posterior pole examination during a standard new or established patient eye exam is bundled into the exam code. CPT 92202 is only separately reportable when the extended examination with drawing and report is a distinct, separately documented service. Append modifier -25 to the exam code when both are billed on the same day.1 |
| 92133 | Scanning computerized ophthalmic diagnostic imaging, anterior segment | OCT of the optic nerve (92133) is separately reportable when medically necessary and independently documented; however, both 92133/92134 and 92202 should not be reflexively billed together every visit. Each must have independent medical necessity documentation. Verify payer-specific bundling policies.4 |
Bundling Alert
The NCCI bundle between CPT 92201 and CPT 92202 is the most critical bundling rule for these codes — they are mutually exclusive and cannot be unbundled with any modifier on the same date of service.2 Similarly, the bundle between 92202 and 92250 (fundus photography) has a bundling indicator of 0, meaning no modifier will override it — if both appear on the same claim for the same date of service, one will be denied. In glaucoma practices that routinely perform both optic nerve drawing and OCT (92133) on the same visit, confirm payer-specific NCCI edit policies; some payers may bundle 92202 with 92133 and require strong documentation of independent medical necessity and modifier -59 to support separate billing.3

Bilateral Billing Rules
CPT 92202 carries bilateral indicator 2 — the Medicare Physician Fee Schedule rate for this code already accounts for unilateral or bilateral performance, and the payment amount is the same regardless of how many eyes are examined. Never append modifier -50, -RT, or -LT to 92202 — this applies to both Medicare and most commercial payers following Medicare billing guidelines. Report only one unit per encounter. Some commercial payers may deviate from this rule; always verify individual payer contracts, but absent specific payer instructions to the contrary, follow the bilateral indicator 2 rule and submit without a laterality modifier.12
🏷️ Modifier Reference
| Modifier | Name | When to Apply |
|---|---|---|
| -25 | Significant, Separately Identifiable E/M Service | Append -25 to the eye exam or E/M code (not to 92202) when a comprehensive or intermediate eye exam is billed on the same day and represents a significant, separately identifiable service beyond the decision to perform extended ophthalmoscopy. Both services must be independently documented with their own clinical content.1 |
| -59 | Distinct Procedural Service | Apply to 92202 when a payer-specific bundling edit would otherwise package it into another same-day diagnostic service (e.g., 92133/92134 OCT) and the services are genuinely distinct with separate documented medical necessity. Do not use -59 to override the NCCI 92201/92202 mutual exclusion or the 92202/92250 bundle — those have indicator 0 and cannot be overridden.23 |
| -52 | Reduced Services | Use if the extended posterior pole examination was initiated but only partially completed due to media opacity, patient cooperation issues, or other clinical factors preventing a complete exam and drawing. Document the reason for incomplete service in the record.4 |
| -53 | Discontinued Procedure | Apply if the procedure was initiated but terminated before any clinically useful examination or labeled drawing was produced due to a significant adverse event or patient emergency. |
| -GQ | Via Asynchronous Telecommunications | Used when extended ophthalmoscopy interpretation is provided via store-and-forward telehealth in applicable state/payer contexts. Verify telehealth eligibility for 92202 under current CMS and MAC policy. |
| -GT | Via Interactive Audio and Video | Applied when the service is delivered via real-time interactive telehealth. Confirm 92202 remains on the applicable telehealth-eligible procedure list for the date of service. |
Modifiers NOT applicable to 92202
🩺 Common ICD‑10‑CM Pairings
Primary Diagnosis Group
| ICD‑10 | Description | HCC? | Notes |
|---|---|---|---|
| H40.1111 | Primary open-angle glaucoma, right eye, mild stage | No | Most common pairing for 92202; used when detailed optic nerve drawing documents structural glaucomatous damage at the posterior pole. Always code to laterality and stage — codes range from H40.1111–H40.1134.1 |
| H40.1121 | Primary open-angle glaucoma, left eye, mild stage | No | Mirror code for the left eye; code both lateralities when bilateral POAG is documented, as no bilateral POAG code exists in ICD-10-CM. |
| H35.3190 | Nonexudative age-related macular degeneration, unspecified eye, unspecified stage | No | Use when AMD is documented but laterality and stage are not specified; always prefer a laterality- and stage-specific code (e.g., H35.3111 for right eye, early dry AMD) when documentation supports it.3 |
| H35.3211 | Exudative age-related macular degeneration, right eye, with active choroidal neovascularization | No | High-specificity pairing for patients receiving anti-VEGF treatment; the macular drawing documents CNV border location and subretinal fluid extent. |
| H47.311 | Drusen of optic disc, right eye | No | Optic disc drusen can mimic optic nerve edema; 92202 documents the buried vs. superficial drusen characteristics and any associated changes.4 |
Secondary Group
| ICD‑10 | Description | HCC? | Notes |
|---|---|---|---|
| H35.81 | Retinal edema | No | May accompany posterior pole tumors or AMD; code when edema is a documented finding driving the extended examination. Confirm edema is macular/posterior pole in location to support 92202. |
| D31.21 | Benign neoplasm of right retina | No | For posterior pole tumors (e.g., choroidal nevus near the optic disc or macula); 92202 is used to map the lesion’s proximity to the fovea and disc margin. |
Etiology / Complication
| ICD‑10 | Description | HCC? | Notes |
|---|---|---|---|
| H40.051 | Ocular hypertension, right eye | No | Pre-glaucomatous state; 92202 may be performed to document structural optic nerve baseline before a treatment decision is made.2 |
| H47.141 | Foster Kennedy syndrome, right eye | No | Rare; include when optic disc pathology is part of a broader neurological diagnosis that prompted the extended optic nerve drawing. Use only if clinically supported. |
Coding Specificity Reminder
Glaucoma ICD-10-CM codes require four levels of specificity: (1) glaucoma type, (2) laterality, (3) stage, and (4**) in some categories an additional character**. AMD codes similarly require laterality, type (dry vs. wet), and stage (early, intermediate, advanced, or indeterminate). Never default to an unspecified code if the physician’s documentation provides the laterality and clinical stage — payers and quality programs increasingly audit for specificity, and using unspecified codes when specific documentation exists is a documentation integrity issue. When both eyes are affected, ICD-10-CM has bilateral codes for some conditions (e.g.,H40.1131 for bilateral POAG severe stage) — use the bilateral code when it exists rather than listing two separate laterality codes.34
🏥 MS‑DRG Considerations
CPT 92202 is a Medicine/diagnostic ophthalmology service that does not independently drive MS-DRG assignment. Inpatient scenarios involving extended posterior pole ophthalmoscopy are uncommon, but may arise when a glaucoma patient is admitted for another condition and the ophthalmologist evaluates optic nerve status at bedside, or when a patient with a choroidal tumor is admitted for biopsy planning. In these contexts, the principal diagnosis (driving the admission) and any surgical ICD-10-PCS procedures determine DRG assignment — not the diagnostic ophthalmoscopy service. DRGs most commonly associated with posterior pole ophthalmic diagnoses fall under MDC 02 (Diseases and Disorders of the Eye), particularly DRG 124 (Other Disorders of the Eye with MCC), DRG 125 (with CC), and DRG 126 (without CC/MCC). For glaucoma-primary admissions, DRGs 124–126 again apply. Posterior pole tumor admissions with surgical intervention may fall under DRG 121 or 122. CPT 92202 on the professional claim does not affect the facility’s DRG assignment.14
🔧 ICD‑10‑PCS Equivalents
Note
CPT 92202 is a physician-performed diagnostic visualization procedure with no precise single ICD-10-PCS equivalent. ICD-10-PCS captures eye examination under Section 0 (Medical and Surgical) — Root Operation J (Inspection) and ocular measurement under Section 4 (Measurement and Monitoring). No PCS table specifically codes for “optic nerve drawing” or “macular ophthalmoscopy” as distinct root operations.
| PCS Code | Full Description | Modality |
|---|---|---|
| 08JXZZZ | Inspection of Eye, External Approach | Physician visual examination of the eye — closest PCS equivalent for ophthalmoscopy without a device |
| 08J0XZZ | Inspection of Right Eye, External Approach | Laterality-specific right eye inspection |
| 08J1XZZ | Inspection of Left Eye, External Approach | Laterality-specific left eye inspection |
| 4A07XVZ | Measurement of Eye, Ophthalmologic, External Approach | Broader ophthalmologic diagnostic measurement at the posterior pole |
PCS Character Analysis (using 08JXZZZ as primary example)
| Position | Character | Value | Definition |
|---|---|---|---|
| 1 | Section | 0 | Medical and Surgical — the primary PCS section for physician-performed diagnostic and therapeutic procedures on body parts. |
| 2 | Body System | 8 | Eye — encompasses all ocular structures including the optic nerve, retina, macula, and vitreous. |
| 3 | Root Operation | J | Inspection — visually and/or manually exploring a body part; accurately reflects the extended ophthalmoscopic examination of the optic nerve and macula. |
| 4 | Body Part | X | Eye — body part value X (Eye, unspecified) used when not distinguishing laterality; use 0 (Right Eye) or 1 (Left Eye) when laterality is specified. |
| 5 | Approach | X | External — the condensing lens and slit lamp illuminate and visualize the posterior segment through the dilated pupil without incision. |
| 6 | Device | Z | No Device — no implantable or permanently inserted device is used during diagnostic posterior pole ophthalmoscopy. |
| 7 | Qualifier | Z | No Qualifier — no additional specification required for the inspection procedure in the PCS table. |
Root Operation Comparison
- Inspection (J) vs. Measurement (0, Section 4): Use Inspection (08JXZZZ) when the clinical intent is physician visual examination and documentation of anatomic structures — this maps most directly to the clinical act of optic nerve head and macular evaluation in 92202. Use Measurement (4A07XVZ) when the intent is quantifying a specific physiological or structural parameter (e.g., IOP, corneal thickness).
- Section 0 (M&S Inspection) vs. Section B (Imaging): If a photograph or digital image is captured as part of the posterior pole evaluation (e.g., fundus photography), Section B (Imaging, Eye body system B80xx) codes would apply to the image acquisition. CPT 92202 itself is a real-time physician-performed examination, not an image capture service, so Section 0 Inspection is the closer functional PCS equivalent.
- ICD-10-PCS and 92202 in the inpatient setting: Diagnostic ophthalmoscopy codes in PCS are rarely reported on UB-04 facility claims unless the facility has a policy to capture diagnostic examination procedures in PCS. The physician’s extended ophthalmoscopy service is captured on the CMS-1500/professional claim using CPT 92202.
📝 Coding Examples
Example 1 — Glaucoma Monitoring Visit with Extended Optic Nerve Drawing
Clinical Scenario:
A 72-year-old established patient with bilateral primary open-angle glaucoma, moderate stage, returns for a scheduled glaucoma monitoring visit. The physician performs IOP measurement, visual field review, and an intermediate ophthalmological examination. Following the exam, the physician performs a dedicated extended posterior pole evaluation with a 90D lens at the slit lamp, carefully evaluating the optic nerve head in both eyes and documenting a new inferior notch and disc hemorrhage at the 6-o’clock position in the right eye not present on the prior drawing from six months ago. A detailed labeled optic nerve drawing is produced for each eye, with clock-hour neuroretinal rim annotations. The physician writes a separate signed interpretation and report identifying the new hemorrhage and notching as evidence of glaucomatous progression, and updates the management plan accordingly.
| Field | Code | Rationale |
|---|---|---|
| CPT 1 | 92012-25 | Intermediate established patient eye exam; modifier -25 on the exam code signals a significant, separately identifiable service beyond the decision to perform extended ophthalmoscopy. The exam included IOP, anterior segment, VF review, and general posterior survey with independent medical decision-making.1 |
| CPT 2 | 92202 | Extended ophthalmoscopy with optic nerve drawing and interpretation/report, bilateral. Single unit — bilateral indicator 2. No -50, -RT, or -LT. The new disc hemorrhage and notching findings documented on the drawing support the medical necessity for this service.2 |
| PDx | H40.1122 | Primary open-angle glaucoma, right eye, moderate stage — the laterality with new progression findings is coded as primary. |
Note
Modifier -25 must be on the exam code (92012), not on 92202. Both the exam note and the 92202 interpretation/report must exist as discrete, separately complete documents in the medical record. The labeled optic nerve drawing must be individualized and signed — a blank or carry-forward template drawing does not meet documentation requirements.3
Example 2 — Wet AMD Monitoring Between Anti-VEGF Injections
Clinical Scenario:
A 79-year-old established patient with exudative AMD in the right eye managed with intravitreal bevacizumab injections (last injection four weeks ago) presents for an interval monitoring visit. No injection is planned today. The physician performs an intermediate examination and then conducts a dedicated extended macular evaluation with a 90D lens, carefully documenting subretinal fluid distribution, pigment epithelial detachment borders, and areas of geographic atrophy on a labeled posterior pole/macular drawing. A written interpretation and report notes stable dry AMD in the left eye and modestly reduced subretinal fluid in the right eye compared to the prior drawing, supporting continuation of the current injection interval.
| Field | Code | Rationale |
|---|---|---|
| CPT 1 | 92012-25 | Intermediate established patient eye exam; -25 on the exam code. |
| CPT 2 | 92202 | Extended ophthalmoscopy, posterior pole (macular focus), with labeled macular drawing and written interpretation/report. Single unit; bilateral indicator 2 applies even though primarily the right eye is the focus — do not append -RT.24 |
| PDx | H35.3211 | Exudative age-related macular degeneration, right eye, with active choroidal neovascularization. |
Warning
Do NOT bill 92250 (fundus photography) on the same date as 92202 — NCCI edits bundle these two codes with indicator 0, meaning no modifier can override the edit. If fundus photography was also performed today, it cannot be separately reported alongside 92202. Choose the service that provides the greater clinical documentation value and bill only that one on this date.23
Example 3 — Choroidal Nevus Posterior Pole Surveillance, No Concurrent Exam
Clinical Scenario:
A 55-year-old established patient with a documented superior juxtapapillary choroidal nevus in the left eye returns specifically for a surveillance extended posterior pole examination as scheduled. No comprehensive eye exam is performed today. The physician performs dedicated BIO and slit lamp evaluation of the posterior pole, drawing the nevus borders in relation to the optic disc margin and fovea on a labeled posterior pole diagram. Lesion dimensions appear stable. A written interpretation and report documents no change in elevation, pigmentation, or associated subretinal fluid, and notes continued low-risk features. No other service is billed today.
| Field | Code | Rationale |
|---|---|---|
| CPT | 92202 | Extended ophthalmoscopy, drawing of posterior pole lesion (choroidal nevus near optic disc), interpretation/report. Single unit; no concurrent exam billed; no laterality modifiers.14 |
| PDx | D31.22 | Benign neoplasm of left retina — the established surveillance diagnosis driving today’s visit. |
Global period reminder
CPT 92202 carries a global period of 000, so there is no post-procedure period to navigate. If this patient subsequently requires a surgical or laser procedure for the lesion, the 92202 performed at this diagnostic visit is separately billable. If 92202 is performed on the same day as an intraocular procedure (e.g., intravitreal injection 67028), NCCI bundling applies — verify the bundling indicator and whether modifier -59 is appropriate based on payer guidance before billing both services on the same date.2
⚠️ Common Coding Pitfalls
- Pitfall 1 — Billing 92202 without a qualifying labeled drawing: The CPT descriptor requires a drawing. A thorough narrative description of optic nerve cupping or macular pathology — no matter how detailed — does not substitute for a labeled anatomical drawing. This is the #1 audit finding for both 92202 and 92201 and is non-negotiable for claim defensibility.3
- Pitfall 2 — Reporting 92202 and 92201 on the same date: NCCI bundles these codes as mutually exclusive (indicator 0), meaning they cannot be reported together on any date of service and cannot be unbundled with any modifier. If both a peripheral retinal and posterior pole extended examination are genuinely performed, select only one code per the primary clinical service and document accordingly.2
- Pitfall 3 — Reporting 92202 and 92250 on the same date: The NCCI bundle between 92202 and 92250 also carries indicator 0 — no modifier override is possible. Do not reflexively add fundus photography to every 92202 encounter. If both are performed, only one is reportable on that claim date.23
- Pitfall 4 — Appending -RT, -LT, or -50: The bilateral indicator of 2 makes these modifiers inappropriate for 92202. Applying laterality or bilateral modifiers results in claim edits and potential overpayment recovery. Report one unit, no modifier, regardless of laterality.1
- Pitfall 5 — Using a generic or carry-forward drawing template: A stock retinal diagram with no patient-specific markings, or a copy of the prior visit’s drawing without any updated annotations, does not meet the documentation requirements for 92202. Each encounter requires an individualized, current, labeled drawing reflecting the actual findings on that date of service.4
- Pitfall 6 — Failing to produce a separate written interpretation and report: The CPT descriptor explicitly requires “interpretation and report” as distinct elements. Notes that incorporate the extended ophthalmoscopy findings within the general exam narrative — without a separately identifiable physician interpretation section — may not satisfy this requirement at audit. The interpretation and report should be a discrete, signed physician statement that analyzes the drawing findings, compares them to prior studies, and outlines clinical conclusions.3
