Provider Responsibilities, Documentation, and Prior Authorization
Document medical indication for billed SCODI CPT
Coverage for SCODI CPT codes requires a documented medical indication consistent with the policy criteria for the specific SCODI CPT code (92132 — anterior segment; 92133 — posterior/optic nerve; 92134 — posterior/retina; 92137 — posterior/retina including OCT angiography).
Obtain prior authorization for CPT 92133 when required
If the payer requires prior authorization for CPT 92133, obtain authorization and ensure the request includes one of the acceptable ICD-10-CM medical indications listed for optic nerve/orbit imaging.
Link retina SCODI (92134/92137) to listed ICD-10 indications
Use of retina SCODI codes 92134 and 92137 must be associated with one of the listed ICD-10 diagnoses in the retina section; the excerpt does not specify a separate prior authorization process for these codes but links coverage to the enumerated diagnoses.
Link CPT to listed ICD-10 indications for authorization/coverage
Claims for SCODI CPTs 92132, 92133, 92134, and 92137 must be linked to one of the enumerated ICD-10 indications in this policy; providers should document and submit the supporting diagnosis when requesting authorization or submitting claims.
Use SD‑OCT for CQ/HCQ baseline and annual monitoring; refer if unavailable
Spectral-domain OCT (SD-OCT) is required for baseline and annual monitoring of patients on chloroquine (CQ) or hydroxychloroquine (HCQ); providers without SD-OCT should refer beneficiaries to offices or centers that have SD-OCT available.
- Baseline and annual CQ/HCQ evaluation requires SD-OCT per policy (chunk 5).
- Refer patients to facilities with SD-OCT if unavailable in-office (chunk 8).
Include CPT-based interpretation and report documentation
Reference current CPT guidance when coding SCODI services and include the interpretation and report documentation with claims to support the billed procedure.
Document the specific listed ICD-10-CM diagnosis in the medical record
Medical records must document one of the ICD-10-CM diagnoses enumerated in the policy that corresponds to the SCODI procedure billed (e.g., the anterior segment codes for 92132 or optic nerve codes for 92133).
Support CPT 92133 with clinical documentation of listed optic nerve diagnoses
Clinical documentation should support one of the listed ICD-10-CM optic nerve/orbit diagnoses as the medical indication when reporting CPT 92133.
Submit exact listed ICD-10 code that matches the ocular condition
Submit the specific ICD-10 diagnosis code from the policy’s list that corresponds to the patient’s ocular condition (examples include proliferative diabetic retinopathy and retinal vascular occlusion codes) on the claim.
Document ICD-10 medical indication and note coverage is subject to plan/state rules
Providers must document the medical indication (specific ICD-10 diagnosis) supporting the billed SCODI CPT code; coverage decisions remain subject to the member’s coverage terms, exclusions, and state Medicaid provisions.
Avoid billing SCODI for advanced glaucoma damage or glaucoma screening
SCODI is not medically necessary for advanced glaucomatous damage or for screening for glaucoma; use of SCODI for these indications may lead to claim denial.
Denial risk: 92133 billed without listed optic nerve diagnoses
Billing CPT 92133 without one of the listed ICD-10-CM diagnosis codes for optic nerve/orbit indications may trigger denial when the payer expects a matching medical indication.
92133 claims may be denied if no appropriate optic nerve diagnosis is provided
Claims for CPT 92133 may be denied if submitted without an appropriate listed ICD-10-CM diagnosis indicating an optic nerve or visual pathway disorder (examples shown in the policy).
Support retina SCODI claims with a listed ICD-10 diagnosis
SCODI retina imaging claims must be supported by an appropriate ICD-10 diagnosis from the policy’s listed medical indications to be considered for coverage.
Coverage subject to plan terms and state Medicaid provisions
Claims are subject to the Health Plan’s coverage provisions, exclusions and limitations; state Medicaid provisions take precedence where applicable and can affect coverage determinations.
Background and Clinical Context
Scanning Computerized Ophthalmic Diagnostic Imaging (SCODI), which includes OCT and OCT angiography (OCTA), produces high-resolution cross-sectional and vascular flow images of anterior and posterior ocular structures. SCODI is used clinically to evaluate the cornea and anterior segment, the optic nerve and retinal nerve fiber layer, and the retina and choroid for conditions such as macular disease, retinal vascular occlusion, neoplasms, inflammatory and degenerative disorders. OCTA provides noninvasive visualization of retinal and choroidal vasculature but does not detect dye leakage; spectral-domain OCT (SD-OCT) is the preferred modality for baseline and annual monitoring of patients on chloroquine or hydroxychloroquine.
Definitions and Procedure Descriptions
Policy Updates and Revision History
Updated coding to include newly published ICD-10 codes for neovascular secondary angle closure glaucoma and thyroid orbitopathy; updated references (Approval Date: 10/2025).
Updated coding to include newly published ICD-10 codes for neovascular secondary angle closure glaucoma and thyroid orbitopathy; updated references (Date: 08/2025).
Approval of revisions including addition of CPT 92137 (posterior retinal SCODI including OCT angiography), revised CPT descriptors for 92132, 92133, and 92134, and removal of vitreous membranes/strands/degeneration from medical indications for posterior retina 92134 (Approval Date: 07/2025).
Added CPT 92137 (posterior retinal SCODI including OCT angiography) and removed vitreous membranes, strands and degeneration from medical indications for posterior retina 92134 (Date: 05/2025).
Recent policy updates include additions and descriptor revisions that affect prior authorization and coverage linkage. Notably, the document records multiple approval and update entries through 2025 reflecting changes to CPT descriptors and the addition of a new retina code. Providers and authorizations teams should note these updates when submitting requests and ensure the claim includes the listed ICD-10 indication mapped to the appropriate CPT.
The policy now lists four covered CPT codes with revised language: CPT 92132, CPT 92133, CPT 92134 (descriptor revised), and the newly added CPT 92137 for posterior retinal SCODI including OCT angiography. The updated code descriptors and the addition of 92137 should be used for claims and prior authorization requests where OCTA is performed.
The removal of vitreous membranes, strands and degeneration from the medically indicated diagnoses for posterior retina SCODI (CPT 92134) is recorded as a material change in the policy update history. After these edits, procedures performed solely for those vitreous findings are not listed as supported indications for posterior retina SCODI and should not be billed as such without another covered retina diagnosis.
