👁️ CPT 92060 — Sensorimotor Examination With Multiple Measurements of Ocular Deviation
Quick Reference
wRVU: 0.51 | Global Period: XXX | Assistant Payable: No | Bilateral Indicator: 2 Rule: The bilateral indicator of 2 means the RVU already assumes assessment of both eyes, so a 150% bilateral adjustment never applies and modifier -50 is not separately reimbursed.² The “(separate procedure)” parenthetical means it is bundled into any more comprehensive eye service performed the same session unless a distinct, medically necessary purpose is documented.³ PC/TC indicator 1 means both a professional (interpretation) and technical (testing) component exist, so -26/-TC apply when the physician and facility bill separately.
📋 Clinical Description
CPT 92060 describes a quantitative sensorimotor examination that goes beyond the basic ocular-motility check bundled into every comprehensive eye exam. Using prism bars, the Hess screen, or the Lancaster red-green test, the examiner measures the actual degree of ocular deviation in multiple positions of gaze and at multiple fixation distances, then correlates those findings with the patient’s subjective report of diplopia.⁴ This distinguishes it from the basic sensorimotor screen embedded in 92014 or 99215, which only documents whether motility is “full” or restricted without quantifying the deviation.
The test is most often ordered when a basic exam already flagged an abnormality and the physician needs objective, reproducible numbers to guide surgical planning, monitor a paretic muscle over time, or document progression of a restrictive process such as thyroid eye disease. Compared to sibling code 92065 (orthoptic/pleoptic training), which is therapeutic, 92060 is purely diagnostic. Compared to 92081 (visual field exam), which maps the visual field itself, 92060 specifically measures ocular alignment and motor function.
This procedure may be performed in the following clinical contexts:
- Preoperative strabismus workup — quantifying deviation in multiple gaze positions to plan muscle recession/resection amounts.
- Acute cranial nerve palsy — serial measurements to track resolution or worsening of a third, fourth, or sixth nerve palsy.
- Post-stroke diplopia evaluation — objective documentation of restrictive or paretic patterns following a cerebrovascular event.
- Thyroid eye disease monitoring — tracking progressive restrictive myopathy over serial visits.
- Post-traumatic orbital fracture follow-up — assessing entrapment-related motility restriction before or after repair.
🔬 Anatomical & Procedural Considerations
| Variant | Mechanism | Key Notes |
|---|---|---|
| Prism-based quantification | Prism bars are placed over the deviating eye until image fusion or neutralization is achieved, giving a prism-diopter measurement of deviation at distance and near. | This is the most common technique in general ophthalmology and is what most payers expect documented when 92060 is billed. |
| Hess screen testing | A red-green or projection Hess screen plots each eye’s field of fixation on a grid, comparing the two to isolate which specific muscle is under- or over-acting. | Especially useful in paretic strabismus to localize a single weak muscle rather than a global motility deficit. |
| Lancaster red-green test | Similar principle to the Hess screen using colored streak projectors, historically favored in neuro-ophthalmology practices for cranial nerve palsy localization. | Requires a darkened room and specialized equipment, so it is less commonly available in general community ophthalmology settings. |
Clinical Pearl
The “separate procedure” designation is the single biggest audit trigger for this code. If the sensorimotor exam is performed as a routine part of the same-day comprehensive eye exam or E/M visit with no distinct, separately documented indication, most payers will bundle it and deny separate payment — documentation needs to show why the quantitative test was medically necessary beyond the baseline exam.
✅ Procedure Includes
- Measurement of ocular deviation in primary gaze plus at least one secondary position (up, down, right, or left gaze).
- Testing at both distance and near fixation when clinically indicated.
- Use of prism bars, Hess screen, or Lancaster red-green test to obtain quantitative deviation values.
- Correlation of measured deviation with the patient’s subjective diplopia complaints.
- Physician interpretation of the measurement pattern to localize the affected muscle(s) or nerve.
- A written report summarizing findings and clinical impression.
❌ Excludes / Do Not Report Together
| Code | Description | Relationship |
|---|---|---|
| 92081 | Visual field examination, limited | Tests a different function (visual field mapping, not ocular motility); may be reported same day only with documentation showing distinct medical necessity for each. |
| 92065 | Orthoptic/pleoptic training | 92065 is therapeutic re-training, not diagnostic measurement; reporting both same-day requires clear separation of diagnostic versus therapeutic intent. |
| 92018 | Ophthalmoscopy, general, under anesthesia | Bundled under NCCI when performed as part of the same anesthetized exam session; 92060 is not separately payable in that context. |
| 99213 | Office/outpatient E/M, established patient, low complexity | The “separate procedure” language means 92060 is bundled into a same-day E/M unless modifier -25 is supported by a clearly distinct, medically necessary reason for the E/M service. |
Bundling Alert
Because 92060 carries a global period of XXX rather than a 0/10/90-day surgical package, there is no postoperative-period bundling risk in the traditional sense — the audit risk instead sits entirely on same-day bundling with E/M and other diagnostic tests. NCCI edits bundle 92060 with several E/M and telehealth-adjacent codes (99211, 99446-99452), and payers frequently deny it outright when billed alongside a routine comprehensive eye exam without a documented, separate clinical trigger.⁵

|---|---|
| Work RVU | 0.51 |
| Global Period | XXX (diagnostic test — global concept does not apply) |
| Bilateral Indicator | 2 — RVU already assumes bilateral testing |
| Assistant Surgeon | Not applicable (non-surgical) |

| PC/TC Split | 1 — professional and technical components both exist |
| Modifier -51 Exempt | No |
| Anesthesia | None required |
Bilateral Billing Rules
Because the code descriptor requires assessment of “multiple measurements of ocular deviation,” CMS treats the test as inherently bilateral, so the RVU already accounts for both eyes being evaluated in a single session. Appending modifier -50 or billing with -RT/-LT to double the unit count is inappropriate and will trigger a payment reduction or denial on audit. If only one eye genuinely requires testing due to monocular pathology, documentation should still support a single unit without a bilateral modifier.
🏷️ Modifier Reference
| Modifier | Name | When to Apply |
|---|---|---|
| -26 | Professional Component | Use when the physician’s interpretation and report are billed separately from a facility that owns the equipment and staff performing the technical portion. |
| -TC | Technical Component | Use when only the facility/technical portion (equipment, technician time) is billed, with the physician’s interpretation billed separately elsewhere. |
| -52 | Reduced Services | Appropriate when only a partial quantitative measurement was completed (e.g., primary gaze only, no secondary positions) due to patient limitations. |
| -59 | Distinct Service | Use to unbundle 92060 from another same-day procedure when both are medically necessary and separately documented, most often against NCCI-edited pairs. |
| -25 | Significant, Separately Identifiable E/M | Applied to the E/M code (not 92060 itself) when a significant, separately documented E/M service is performed the same day as the sensorimotor exam. |
| -RT | Right Side | Rarely applicable since the RVU assumes bilateral testing; only used with strong documentation that testing was truly unilateral and payer policy permits laterality reporting. |
| -LT | Left Side | Same limited applicability as -RT — confirm payer policy before use, since most will still expect a single global unit. |
| -51 | Multiple Procedures | Applies when 92060 is reported with other separately payable procedures in the same session subject to multiple-procedure reduction rules. |
🩺 Common ICD-10-CM Pairings
Primary Diagnosis Group
| ICD-10 | Description | HCC? | Notes |
|---|---|---|---|
| H49.21 | Sixth [abducent] nerve palsy, right eye | No | Classic indication for serial 92060 testing to track resolution of an acquired paretic strabismus. |
| H49.22 | Sixth [abducent] nerve palsy, left eye | No | Same clinical logic as H49.21, mirrored laterality. |
| H50.011 | Monocular esotropia, right eye | No | Comitant strabismus requiring quantitative deviation measurement for surgical planning. |
| H50.012 | Monocular esotropia, left eye | No | Mirrored laterality of H50.011. |
| H50.05 | Alternating esotropia | No | Supports 92060 when fixation preference alternates and both eyes need quantified deviation. |
Secondary Group
| ICD-10 | Description | HCC? | Notes |
|---|---|---|---|
| H53.2 | Diplopia | No | Frequently the presenting symptom that triggers the order for a quantitative sensorimotor exam. |
| H49.9 | Unspecified paralytic strabismus | No | Acceptable when a specific cranial nerve has not yet been identified, though specificity is preferred once known. |
Etiology / Complication
| ICD-10 | Description | HCC? | Notes |
|---|---|---|---|
| G52.7 | Disorders of multiple cranial nerves | No | Supports medical necessity when diplopia stems from a multi-nerve process rather than an isolated palsy. |
| I63.9 | Cerebral infarction, unspecified | Yes | Ties the ocular motility deficit to a stroke etiology; relevant for HCC capture when the stroke itself is separately documented as active. |
Coding Specificity Reminder
Always code to the laterality and specific cranial nerve or muscle involved when the documentation supports it — unspecified codes like H49.9 invite payer scrutiny and understate clinical complexity. When diplopia is the chief complaint but no strabismus diagnosis has been confirmed yet, H53.2 alone may be the only appropriate code until testing establishes the underlying motility disorder. Never default to a parent-level code when a fully specified child code is documented in the chart.
🏥 MS-DRG Considerations
CPT 92060 is a professional-fee diagnostic test and has no direct MS-DRG impact on the inpatient facility side, since MS-DRG assignment is driven by ICD-10-PCS procedure coding rather than CPT. In the rare inpatient encounter where a sensorimotor exam is performed profee-side (e.g., a hospitalized stroke patient with new diplopia), the professional charge is coded and billed independently of the facility’s DRG-bearing claim. The underlying diagnosis — such as I63.9 cerebral infarction — is what drives DRG and MDC assignment on the facility side, not the diagnostic eye test itself. Coders should ensure the profee claim and the facility claim are not conflated when this test occurs during an inpatient stay.
🔧 ICD-10-PCS Equivalents
There is no true ICD-10-PCS equivalent for this code. PCS Section 4 (Measurement and Monitoring) does not define a body system for ocular motility or extraocular muscle function, and diagnostic eye tests of this type are not represented in the PCS code set at all — PCS exists to capture inpatient facility procedures, and a bedside/office sensorimotor exam does not meet that threshold. If a PCS-coded inpatient procedure is performed in conjunction with the underlying condition (for example, cerebral angiography for a stroke workup), that would be coded separately under its own PCS root operation and is not a crosswalk from 92060.
Root Operation Comparison
- Not applicable — 92060 has no PCS crosswalk since it is a diagnostic measurement, not a procedure captured under any PCS root operation.
- If the underlying etiology requires an inpatient procedural workup (e.g., imaging for suspected aneurysm causing a nerve palsy), code that procedure independently using its own PCS logic rather than attempting to map it from 92060.
📝 Coding Examples
Example 1
Clinical Scenario: A 58-year-old presents to neuro-ophthalmology with new-onset horizontal diplopia worse at distance, three weeks after a right MCA stroke. The physician performs prism-bar measurements in primary, right, and left gaze at both distance and near, correlating findings with the patient’s diplopia. Measurements confirm a right lateral rectus underaction consistent with a partial sixth nerve palsy. A written report is generated documenting the deviation pattern and localization. No other procedure is performed this visit.
| Field | Code | Rationale |
|---|---|---|
| CPT | 92060 | Quantitative, multi-position prism measurement with interpretation and report fully meets the code descriptor. |
| PDx | H49.21 | Confirmed right sixth nerve palsy is the specific, laterality-documented diagnosis supporting medical necessity. |
Note
Because this stroke is recent and directly caused the palsy, linking I63.9 as a secondary diagnosis on the encounter (if still active per documentation) strengthens medical necessity and supports HCC capture on the facility/risk-adjustment side.
Example 2
Clinical Scenario: A 34-year-old established patient returns for a scheduled comprehensive eye exam. During the exam, the basic motility screen is normal, and no diplopia or restriction is reported or observed. The physician nonetheless orders a sensorimotor exam “for completeness” and bills it alongside the comprehensive exam code.
| Field | Code | Rationale |
|---|---|---|
| CPT 1 | 92014 | Comprehensive established-patient eye exam already includes a basic motility check. |
| CPT 2 | 92060 | Not separately billable — no documented abnormal finding or distinct clinical indication triggered the quantitative test. |
| PDx | — | No qualifying diagnosis exists to support medical necessity for the separate procedure. |
Warning
Example 3
Clinical Scenario: A 6-year-old is seen for preoperative strabismus evaluation prior to scheduled extraocular muscle surgery. The pediatric ophthalmologist performs Hess screen testing to quantify the degree of monocular esotropia in the left eye across multiple gaze positions, generating measurements used to calculate planned muscle recession amounts. A formal interpretation and report is placed in the chart.
| Field | Code | Rationale |
|---|---|---|
| CPT | 92060 | Hess screen quantification with interpretation and report performed specifically for surgical planning meets full code criteria. |
| PDx | H50.012 | Left monocular esotropia is the fully specified, laterality-documented diagnosis driving both the test and the planned surgery. |
Global period reminder
Since 92060 carries global period XXX, this preoperative test is not part of any 90-day surgical package and is separately payable from the strabismus surgery itself, provided it is performed and documented as a distinct diagnostic encounter rather than bundled same-day pre-op paperwork.
⚠️ Common Coding Pitfalls
- Pitfall 1: Billing 92060 as a routine add-on to every comprehensive eye exam regardless of findings — payers expect a documented abnormal motility finding or diplopia complaint driving the order.
- Pitfall 2: Appending modifier -50 or double-billing with -RT and -LT — the bilateral indicator of 2 means the code already reflects bilateral assessment in a single unit.
- Pitfall 3: Coding to unspecified diagnoses like H49.9 when the chart clearly documents which cranial nerve and side is affected — specificity is required when available.
- Pitfall 4: Failing to append -25 to the E/M code when both a significant E/M and 92060 are performed the same day, resulting in bundling denials that could have been avoided with proper modifier use.
- Pitfall 5: Confusing 92060 with the basic sensorimotor screen already bundled into 920x4 comprehensive exam codes — only the quantitative, prism/Hess/Lancaster-based test qualifies for separate reporting.
- Pitfall 6: Reporting -26/-TC incorrectly in an integrated setting where the same entity owns both the professional and technical components — no modifier should be appended when billing globally.
