No material clinical or coverage changes in this revision.
Coverage Criteria
Retisert / Yutiq (medical necessity)
Covered when ALL of the following are met:
Retisert is FDA‑approved for chronic non‑infectious posterior uveitis; Yutiq is approved for chronic noninfectious posterior uveitis and is deliverable in an office setting.
Policy requires failure of or intolerance to conventional therapy prior to implant.
Presence of active ocular or periocular infection is a contraindication and will trigger denial.
Glaucoma with cup‑to‑disc ratio >0.8 is a contraindication to Retisert/Yutiq.
Iluvien (medical necessity)
Covered when ALL of the following are met:
Iluvien is indicated for DME in patients previously treated with corticosteroids who tolerated them.
Documentation of prior corticosteroid treatment is required for Iluvien candidacy.
Absence of clinically significant IOP rise during prior steroid course is required per product labeling and policy.
Active ocular or periocular infection is a contraindication to Iluvien.
Iluvien therapy is not medically necessary for members with glaucoma with cup‑to‑disc ratio >0.8.
Indication evidence summaries
Clinical indications and evidence summaries present in the document:
Evidence supports implant use for chronic posterior noninfectious uveitis.
Trial evidence demonstrates durable visual benefit for selected DME patients.
Evidence summaries relevant to medical necessity
Clinical findings reported in the document that inform coverage considerations:
Supports consideration in chronic/refractory DME after prior therapies.
High cataract risk; lens status (phakic vs pseudophakic) is relevant to counseling and may affect payer guidance.
Monitoring and management of IOP are required post‑implantation.
Consistent stepwise use in practice; prior treatment history should be documented.
Off‑label uses are informational and generally lack robust evidence for coverage.
Evidence summary and described indications
Covered indications discussed or summarized in this portion of the policy (evidence background and product instructions):
Product summaries and FDA approvals are summarized; see appendices for device delivery and monitoring instructions.
These off‑label indications are discussed as background and not supported by robust prospective data.
Aetna considers fluocinolone acetonide intravitreal implant experimental and investigational for multiple indications where effectiveness has not been established. Examples listed include: anterior uveitis, central retinal vein occlusion, cystoid macular edema, diabetic retinal neurodegeneration, diffuse uveal melanocytic proliferation, inflammatory vitreoretinopathy, intermediate (pars planitis) uveitis, paraneoplastic visual syndromes, radiation-induced maculopathy, retinitis pigmentosa, serpiginous choroiditis, Sjögren’s syndrome–related keratopathy, sympathetic ophthalmia, uveitic glaucoma, and Vogt–Koyanagi–Harada disease/uveitis and combined approaches such as implant plus keratoprosthesis and silicone oil for uveitis-associated hypotony and keratopathy.
Iluvien is contraindicated in patients with ocular or periocular infections, those with glaucoma with a cup-to-disc ratio > 0.8, and individuals with known hypersensitivity to fluocinolone acetonide or product components. The labeling also warns that eyes with an absent or torn posterior lens capsule are at risk of implant migration into the anterior chamber, and patients should be monitored after injection for adverse events including cataract, increased intraocular pressure, endophthalmitis, and retinal detachment.
The National Institute for Health and Care Excellence (NICE) guidance limits use of fluocinolone acetonide intravitreal implant for chronic diabetic macular edema to eyes that are pseudophakic and when the manufacturer provides the implant under the agreed patient access scheme discount, indicating payers may restrict access for phakic eyes or require pricing arrangements.
For off‑label indications, the policy highlights that the available literature is limited—predominantly case reports, small retrospective case series, and single‑center studies—so definitive safety and effectiveness cannot be established and larger prospective trials are needed to inform coverage decisions.
Retisert, Yutiq and Iluvien share important contraindications that may trigger denial of coverage: active ocular or periocular infection and glaucoma with cup-to-disc ratio > 0.8. In addition, Iluvien’s labeling specifies risk of migration when the posterior lens capsule is absent or torn and lists known hypersensitivity to fluocinolone or components as a contraindication.
Use of intravitreal corticosteroid implants for diabetic macular edema may be off‑label for many corticosteroid products, and Iluvien is covered by this policy only for DME in patients who previously received a course of corticosteroids and did not experience a clinically significant rise in intraocular pressure. The document notes intravitreal triamcinolone and other steroids have transient effects and higher rates of cataract and glaucoma, supporting the need to consider prior steroid response when evaluating implant use.
Multiple off‑label uses of fluocinolone implants are reported only in small case series or single‑patient reports (for example, recurrent Irvine‑Gass CME, birdshot retinochoroiditis, and other rare inflammatory conditions), and these publications often emphasize limited sample size, retrospective design, and the need for validation in larger, controlled studies.
Off‑label indications summarized in the background (radiation‑induced maculopathy, paraneoplastic syndromes, Sjögren’s‑related keratopathy, RVO, CME, diabetic retinal neurodegeneration, retinitis pigmentosa, serpiginous choroiditis, JIA‑associated uveitis, etc.) are supported primarily by limited case reports and small retrospective series; the policy states that higher‑quality evidence is needed before these uses can be considered established.

Provider Actions and Requirements
Show prior corticosteroid exposure and steroid tolerability
Document prior corticosteroid treatment and that the patient did not have a clinically significant rise in intraocular pressure during that steroid course, as Iluvien is covered only for DME in patients previously treated with corticosteroids without a clinically significant IOP rise.
- Iluvien coverage requires prior corticosteroid course and absence of clinically significant IOP increase.
- Prior treatment history and response should be included in prior authorization requests.
Document lens status (phakic vs pseudophakic) for consideration
Indicate lens status in the record and prior authorization; guideline and labeling considerations note that use in pseudophakic eyes may be required or preferred (NICE recommendation for pseudophakic lens).
- NICE recommends use only in pseudophakic eyes for chronic DME when prior therapy response was inadequate.
- Iluvien labeling warns of implant migration when the posterior lens capsule is not intact.
Specify device, administration route, and monitoring in PA requests
Specify the implant product, route of administration, and monitoring plan (including IOP and endophthalmitis surveillance) in the prior authorization and procedure documentation; Retisert is surgically inserted while Yutiq and Iluvien are intravitreal injections.
- Retisert: surgically inserted implant into the posterior segment; lasts ~30 months.
- Yutiq and Iluvien: intravitreal injection; monitor for elevated IOP and endophthalmitis; last ~36 months.
Refer to policy history for review dates; no extra PA code rules in this section
Policy history and review dates are provided in the document; the extracted chunks do not state additional explicit prior authorization coding requirements beyond those listed in the CPT/HCPCS coding section.
- Last review: 01/05/2024; Effective date: 11/15/2005; Next review: 08/08/2024.
- No additional PA code requirements are specified in the referenced policy history chunk.
Document failure/intolerance of conventional therapy before implant
For Retisert and Yutiq coverage, document that the member did not respond to or was intolerant of conventional therapy (failed corticosteroid or immunosuppressive therapy).
- Coverage requires chronic non-infectious posterior uveitis and failure or intolerance of conventional treatment.
- Include prior therapy types (corticosteroids, immunosuppressive agents) and reason for failure or intolerance.
Step up to implants after inadequate response to prior DME therapies
For DME, prior therapies should be documented; implants have been evaluated after inadequate response to prior treatments (e.g., macular laser, anti‑VEGF), and NICE recommends use only after inadequate response to available therapies in pseudophakic eyes.
- FAME trials and guidance evaluate implants in patients with persistent DME despite prior therapies.
- NICE restricts use to pseudophakic eyes after inadequate response to available therapies.
Record prior intravitreal therapies and inadequate response
Document prior intravitreal therapy (anti‑VEGF and shorter‑acting steroid injections) and inadequate response, as many studies used fluocinolone implants after prior intravitreal treatments.
- Retrospective series report prior mean anti‑VEGF injections (~3.8) and steroid injections (~1.9) before FAc implant.
- Trials and real‑world reports commonly describe implants used after insufficient response to prior intravitreal therapy.
Include prior topical, intravitreal, and systemic treatments in the record
When requesting authorization, list prior topical steroids, anti‑VEGF agents, dexamethasone implants, or systemic immunosuppression if these were used, since literature commonly reports these therapies before considering fluocinolone implants.
- Case series and reports describe prior use of topical steroids, anti‑VEGF, dexamethasone implants, and systemic immunosuppression.
- Provide treatment dates, agents, response, and intolerance details.
No formal step therapy rules described in these sections
No step therapy requirements (formal mandated sequences) are specified in the cited chunks of this policy.
- The document provides evidence summaries and references but does not define mandatory step therapy protocols in the extracted sections.
Document diagnosis and prior steroid response matching ICD‑10 codes
Ensure the medical record supports the ICD‑10 diagnosis that meets selection criteria (e.g., chronic non‑infectious posterior uveitis for Retisert/Yutiq; DME with prior steroid tolerance for Iluvien).
- Include diagnostic documentation that matches listed ICD‑10 codes associated with covered indications.
- Tie the diagnosis to the documented prior treatments and responses.
Provide prior steroid course and steroid‑tolerability documentation
Include clinical documentation of the prior corticosteroid course and explicit evidence that the patient did not experience a clinically significant rise in intraocular pressure during that course; also document lens status and posterior capsule integrity given migration risk.
- Iluvien coverage requires prior steroid treatment without clinically significant IOP rise.
- Labeling cautions regarding posterior capsule defects and implant migration should be documented.
Document visual acuity and central macular thickness outcomes
When reporting outcomes or supporting continued use, include visual acuity measures (ETDRS letters or logMAR) and central/foveal macular thickness measurements as reported in clinical trials and series.
- FAME trials used ≥15‑letter ETDRS gains as primary outcomes; real‑world studies report BCVA changes and central foveal thickness.
- Include baseline and follow‑up measures and timepoints used.
Document device type, administration route, and follow‑up monitoring plan
Record the implant type placed (Retisert, Yutiq, or Iluvien), the route (surgical insertion for Retisert; intravitreal injection for Yutiq/Iluvien), and the monitoring plan for IOP and signs of endophthalmitis in the procedure and follow‑up notes.
- Retisert: surgically inserted; release profile and ~30‑month duration noted.
- Yutiq/Iluvien: injected intravitreally; monitor for elevated IOP and endophthalmitis; ~36‑month duration.
Do not bill/submit claims when active ocular infection or C/D >0.8 is present
Claims for Retisert or Yutiq will be denied for members with active ocular or periocular infections or glaucoma with a cup‑to‑disc ratio greater than 0.8; Iluvien is likewise contraindicated in these conditions.
- Active ocular or periocular infection is a contraindication to Retisert/Yutiq/Iluvien.
- Glaucoma with cup‑to‑disc ratio > 0.8 is a contraindication and may trigger denial.
Recognize Iluvien contraindications and migration risk to avoid denial
Iluvien is contraindicated in patients with ocular or periocular infections, glaucoma with cup‑to‑disc ratio >0.8, and known hypersensitivity; document these exclusions to avoid denial and note risk of implant migration if posterior capsule is absent or torn.
- Labeling states contraindications: ocular/periocular infection, glaucoma C/D >0.8, hypersensitivity to fluocinolone or components.
- Posterior capsule defects increase risk of anterior chamber migration and should be documented.
Expect payer restrictions (e.g., NICE recommends pseudophakic eyes only)
Be aware that external payers or guidance documents (e.g., NICE) may restrict use to pseudophakic eyes and to pricing/access arrangements; use outside those conditions may result in restricted coverage by some payers.
- NICE recommends use only in pseudophakic eyes and with manufacturer patient access scheme discount.
- Document rationale if treating a phakic eye or when access schemes do not apply.
Monitor and document IOP and endophthalmitis surveillance after insertion
Monitor and document follow‑up for elevated intraocular pressure and signs of endophthalmitis after implant insertion; failure to document monitoring or complications may trigger utilization review or denial of continued coverage.
- Labeling advises patients be monitored following Iluvien injection for elevated IOP and endophthalmitis.
- Appendix instructs monitoring after Yutiq implantation for elevated IOP and endophthalmitis.
No additional provider actions in the referenced policy history chunk
No provider actions are specified in the cited policy history chunk beyond the items already listed; review the full policy for any additional administrative steps.
- Policy history lists review dates but no extra provider action requirements in these chunks.
Background and Evidence Context
Uveitis is intraocular inflammation that can affect anterior, intermediate, posterior, or panuveitis compartments and is a significant cause of visual impairment. Corticosteroids are the mainstay of short‑term therapy and immunosuppressive agents are used for long‑term control. Retisert is a surgically inserted fluocinolone implant and Yutiq/Iluvien are injectable intravitreal implants; these sustained‑release devices were developed to provide prolonged corticosteroid delivery (months to years) to reduce recurrences and the need for adjunctive therapy in chronic posterior non‑infectious uveitis and certain cases of diabetic macular edema.
Posterior non-infectious uveitis
Definition and clinical relevance for coverage of Retisert/Yutiq:
This anatomic definition identifies the target population for Retisert and Yutiq.
Device delivery method differs (surgical insertion for Retisert; intravitreal injection for Yutiq) and monitoring for elevated IOP and endophthalmitis is required after placement.
