D5923 is the CDT code for an interim ocular prosthesis — a temporary artificial eye, used for a limited period (typically during early healing after eye removal) before the definitive (permanent) ocular prosthesis is made. It maintains the socket's shape and supports tissue during healing, and provides an interim appearance, while the eye area heals and stabilizes. It's the temporary counterpart of the definitive ocular prosthesis (D5916).
What D5923 means
D5923 covers an ocular prosthesis, interim. "D" is dental, "59" places it in the maxillofacial prosthetics area, and "23" is this interim ocular prosthesis. An 'ocular prosthesis' is an artificial eye. 'Interim' means temporary — for a limited period, to be replaced by a definitive (permanent) one. So D5923 is a temporary artificial eye used during the healing/transitional phase.
So it's a provisional artificial eye, worn during early healing before the permanent ocular prosthesis is made.
After an eye is removed (enucleation/evisceration — e.g., for cancer, trauma, or a blind painful eye), the socket needs time to heal and the swelling to resolve before a final, well-fitting artificial eye can be made. During this early healing period (weeks to a few months), an interim ocular prosthesis is used. It serves several purposes: maintains the socket — keeps the socket/conjunctival space open and shaped (so it doesn't contract or lose its form), supporting proper healing for the eventual definitive prosthesis; supports the tissues — helps the eyelids and socket tissues heal in good position; provides interim appearance — gives the patient an acceptable temporary eye appearance during healing (better than an empty socket or a clear conformer alone); and bridges to the definitive prosthesis — once healing is complete and the socket is stable, the definitive (custom, fully-matched) ocular prosthesis (D5916) is made. (A 'conformer' — a clear/temporary shaped shell — is often placed right after surgery; the interim ocular prosthesis is a step that may provide a more eye-like temporary appearance during healing.) So D5923 is the temporary artificial eye for the healing phase, distinct from the definitive one (D5916). It's part of the staged rehabilitation after eye loss. Coverage is by report/medical necessity (reconstructive/medical). This code is in the maxillofacial prosthetics area. Documentation supports the claim.
When it's typically used
D5923 is reported for an interim ocular prosthesis — a temporary artificial eye used during the early healing period after eye removal, before the definitive ocular prosthesis is made. It maintains and shapes the socket, supports tissue healing, and provides an interim appearance, bridging to the definitive prosthesis (D5916) once the socket has healed and stabilized.
How much does D5923 cost?
An interim ocular prosthesis's cost reflects a temporary artificial eye (provisional — less elaborate than the definitive, custom-matched one) — typically less than the definitive ocular prosthesis (D5916). Sample fee-schedule values place it below the definitive eye (in the several-hundred-dollars range), varying by region/setting. It's typically a reconstructive (medical) benefit. Verify coverage with the relevant plan.
Is D5923 covered by insurance?
Coverage for an interim ocular prosthesis is usually a reconstructive/medical benefit (part of the staged rehabilitation after eye loss), determined by report and medical necessity. Documentation of the eye removal, the healing phase, and the need for an interim prosthesis (before the definitive one) supports the claim. Coordination with medical coverage is often needed. Verifying how the interim and definitive prostheses are covered helps.
Why an interim eye during healing
The socket must heal before the final eye, and understanding this clarifies the code.
Understanding the healing phase clarifies D5923. After an eye is surgically removed, the socket (and surrounding tissues) need time to heal and settle: swelling resolves — there's initial post-surgical swelling that gradually subsides over weeks; socket stabilizes — the socket's shape and the tissues take time to heal and reach a stable, final form; and only then can a definitive eye be fitted — a permanent, precisely-fitting, fully-matched ocular prosthesis (D5916) should be made on a healed, stable socket (making it too early would mean it soon wouldn't fit well as healing continues).
So there's a gap between surgery and the definitive prosthesis — and during that gap, an interim ocular prosthesis (D5923) is used. It bridges the healing period: providing a temporary eye while the socket heals, so the patient isn't left with an empty socket or only a clear conformer during this time, and the definitive prosthesis is appropriately timed afterward. This is analogous to using interim/provisional restorations elsewhere in dentistry while definitive ones await proper conditions. So an interim eye bridges the healing phase before the definitive one. Understanding this helps patients see that after an eye is surgically removed the socket (and surrounding tissues) need time to heal and settle — swelling resolves (there being initial post-surgical swelling that gradually subsides over weeks), socket stabilizes (the socket's shape and the tissues taking time to heal and reach a stable final form), and only then can a definitive eye be fitted (a permanent, precisely-fitting, fully-matched ocular prosthesis/D5916 should be made on a healed stable socket, making it too early meaning it soon wouldn't fit well as healing continues) — so there being a gap between surgery and the definitive prosthesis and during that gap an interim ocular prosthesis being used (bridging the healing period, providing a temporary eye while the socket heals so the patient isn't left with an empty socket or only a clear conformer during this time, and the definitive prosthesis being appropriately timed afterward), analogous to using interim/provisional restorations elsewhere in dentistry while definitive ones await proper conditions.
What the interim prosthesis does
It shapes the socket and gives an appearance, and understanding this clarifies its role.
Understanding its functions clarifies D5923. The interim ocular prosthesis serves several roles during healing: maintains/shapes the socket — it keeps the socket and conjunctival fornices (the pockets of the socket) open and properly shaped, preventing socket contraction or collapse; a well-maintained socket is important so the definitive prosthesis will fit well (a contracted socket would compromise the final result); supports tissue healing — it helps the eyelids and socket tissues heal in their proper positions (supporting the lids so they retain good form/function); provides interim appearance — it gives the patient an acceptable, more eye-like temporary appearance during the weeks/months of healing (more cosmetically acceptable than an empty socket or a plain clear conformer), which matters for the patient's comfort and confidence while waiting; and conditions for the definitive — by maintaining the socket and tissues in good shape, it sets up the best conditions for fitting the definitive prosthesis.
So the interim prosthesis isn't just a placeholder for appearance — it actively maintains the socket/tissues to ensure a good definitive result, while also restoring an interim appearance. D5923 provides this during the healing phase. So the interim eye maintains the socket and provides appearance. Understanding this helps patients see that the interim ocular prosthesis serves several roles during healing — maintains/shapes the socket (keeping the socket and conjunctival fornices/the pockets of the socket open and properly shaped, preventing socket contraction or collapse, a well-maintained socket being important so the definitive prosthesis will fit well since a contracted socket would compromise the final result), supports tissue healing (helping the eyelids and socket tissues heal in their proper positions, supporting the lids so they retain good form/function), provides interim appearance (giving the patient an acceptable more eye-like temporary appearance during the weeks/months of healing, more cosmetically acceptable than an empty socket or a plain clear conformer, mattering for the patient's comfort and confidence while waiting), and conditions for the definitive (by maintaining the socket and tissues in good shape setting up the best conditions for fitting the definitive prosthesis) — so the interim prosthesis not being just a placeholder for appearance but actively maintaining the socket/tissues to ensure a good definitive result while also restoring an interim appearance.
Interim vs definitive ocular prosthesis
Temporary healing aid vs permanent matched eye, and understanding this clarifies the distinction.
Understanding the distinction clarifies D5923. The interim and definitive ocular prostheses are two stages: interim ocular prosthesis (D5923, this code) — temporary; used during the early healing phase; focuses on maintaining/shaping the socket and providing an acceptable interim appearance; not the fully-refined, permanently-matched eye (it's provisional, serving the healing period); and definitive ocular prosthesis (D5916) — permanent; made once the socket has healed and stabilized; precisely fitted to the final socket and meticulously matched to the fellow eye (iris, sclera, vessels) for the best long-term appearance; the lasting artificial eye.
So the interim one (D5923) is the temporary, healing-phase eye, and the definitive one (D5916) is the permanent, fully-matched eye made afterward. The patient typically progresses from surgery → (conformer/interim prosthesis during healing) → definitive prosthesis once healed. This staging ensures the definitive eye is made under optimal conditions (a healed, stable, well-maintained socket) for the best fit and appearance. D5923 is specifically the interim stage. So D5923 is the temporary stage before the definitive ocular prosthesis. Understanding this helps patients see that the interim and definitive ocular prostheses are two stages — interim ocular prosthesis (D5923, this code, temporary, used during the early healing phase, focusing on maintaining/shaping the socket and providing an acceptable interim appearance, not the fully-refined permanently-matched eye since it's provisional serving the healing period) and definitive ocular prosthesis (D5916, permanent, made once the socket has healed and stabilized, precisely fitted to the final socket and meticulously matched to the fellow eye/iris, sclera, vessels for the best long-term appearance, the lasting artificial eye) — so the interim one being the temporary healing-phase eye and the definitive one the permanent fully-matched eye made afterward, the patient typically progressing from surgery → conformer/interim prosthesis during healing → definitive prosthesis once healed, this staging ensuring the definitive eye is made under optimal conditions (a healed, stable, well-maintained socket) for the best fit and appearance, D5923 specifically being the interim stage.
Where D5923 fits in the codes
D5923 is the interim ocular code, and understanding this clarifies the coding.
Understanding where D5923 sits clarifies the coding. D5923 is among the maxillofacial prosthetics codes (D5900s), specifically the eye-related prosthesis codes, as the interim ocular version: D5916 (ocular prosthesis — definitive artificial eye), D5923 (ocular prosthesis, interim, this code — temporary artificial eye), D5915 (orbital prosthesis — eye plus surrounding structures), D5928 (orbital prosthesis, replacement). Alongside are the other facial-feature prostheses (nasal D5913, auricular D5914, facial D5919) and the moulages (D5911/D5912).
So D5923 is precisely: an ocular prosthesis, interim (a temporary artificial eye for the healing phase). Its definitive counterpart is D5916 (the permanent ocular prosthesis it leads to). It's distinguished from D5916 by being interim/temporary (vs the definitive eye), and from the orbital prostheses (D5915/D5928) by being an eye-only prosthesis (intact lids/socket). The prosthodontist/ocularist codes D5923 for the temporary eye during healing. So D5923 is the interim ocular prosthesis among the codes. Understanding this helps patients see that D5923 is among the maxillofacial prosthetics codes (D5900s), specifically the eye-related prosthesis codes, as the interim ocular version — D5916 (ocular prosthesis, definitive artificial eye), D5923 (ocular prosthesis, interim, this code, temporary artificial eye), D5915 (orbital prosthesis, eye plus surrounding structures), D5928 (orbital prosthesis, replacement) — alongside the other facial-feature prostheses (nasal D5913, auricular D5914, facial D5919) and the moulages (D5911/D5912) — so D5923 is precisely an ocular prosthesis, interim (a temporary artificial eye for the healing phase), its definitive counterpart being D5916 (the permanent ocular prosthesis it leads to), distinguished from D5916 by being interim/temporary (vs the definitive eye) and from the orbital prostheses (D5915/D5928) by being an eye-only prosthesis (intact lids/socket), the prosthodontist/ocularist coding D5923 for the temporary eye during healing.
Frequently asked questions
- What is the D5923 dental code?
- It's an interim ocular prosthesis — a temporary artificial eye used for a limited period (typically during early healing after eye removal) before the definitive (permanent) artificial eye is made. It maintains and shapes the socket, supports tissue healing, and provides an interim appearance while the eye area heals and stabilizes. It's the temporary counterpart of the definitive ocular prosthesis (D5916).
- Why is a temporary eye needed first?
- After an eye is removed, the socket needs weeks to months to heal, with swelling subsiding and the tissues settling into their final form. A permanent, precisely-matched artificial eye should be made on a healed, stable socket — making it too early would mean it soon wouldn't fit. So an interim prosthesis bridges the healing period before the definitive eye is made.
- What does the interim prosthesis do?
- It maintains and shapes the socket (preventing it from contracting or collapsing, so the definitive eye will fit well), supports the eyelids and tissues in good position during healing, and provides an acceptable temporary eye-like appearance (better than an empty socket or a plain clear conformer) — which matters for the patient's comfort and confidence while waiting for the permanent prosthesis.
- How is it different from the definitive ocular prosthesis (D5916)?
- The interim one (D5923) is temporary — used during healing, focused on maintaining the socket and providing an interim appearance. The definitive one (D5916) is permanent — made after the socket has healed and stabilized, precisely fitted and meticulously matched to the fellow eye for the best long-term result. So D5923 is the healing-phase eye; D5916 is the final, fully-matched eye made afterward.
- How long is an interim eye worn?
- Typically through the early healing period after eye removal — often weeks to a few months — until the swelling has resolved and the socket has stabilized enough to make the definitive prosthesis. The exact timing depends on individual healing. Your prosthodontist/ocularist (with the surgical team) determines when the socket is ready for the permanent artificial eye.
- Is it covered, and what does it cost?
- Cost reflects a temporary (provisional) artificial eye — typically less than the definitive ocular prosthesis (often in the several-hundred-dollars range), varying by region/setting. It's typically a reconstructive (medical) benefit, determined by report/medical necessity. Documentation of the eye removal and healing phase helps. Coordination with medical coverage is often needed. Verify your coverage.
