H33.003

🧬 ICD-10 CM H33.003 — Unspecified Retinal Detachment with Retinal Break, Bilateral

Billable Code Confirmed

ICD-10 CM H33.003 is a valid, billable 6-character ICD-10-CM code for FY2025. All six characters are present: H33 (category) + .0 (retinal detachment with break) + 0 (unspecified break type) + 3 (bilateral). No 7th character is required.

Non-Billable Parent Codes — Never Submit These

• ❌ H33.00 — 5-character header — missing laterality character

• ❌ H33.0 — 4-character header — missing break specification and laterality

  Always submit H33.003 (all 6 characters) when bilateral involvement with an unspecified break is documented.

Clinical Context: "Unspecified" Break vs. Specific Break

ICD-10 CM H33.003 indicates a rhegmatogenous retinal detachment (RRD)—meaning a detachment caused by fluid passing through a break in the retina. However, the 00 signifies the type or number of breaks (single, multiple, giant tear, or dialysis) is unspecified. If the operative report or exam specifies the nature of the break, a more specific code (like H33.013 for a single break, or H33.023 for multiple breaks) is strongly preferred over H33.003.

🔍 Code Description

ICD-10 CM H33.003 classifies a bilateral rhegmatogenous retinal detachment where the specific nature, quantity, or morphology of the causative retinal break(s) has not been specified in the medical record.²

A rhegmatogenous retinal detachment occurs when a full-thickness tear or break in the sensory retina allows liquefied vitreous to track into the subretinal space, separating the neurosensory retina from the underlying retinal pigment epithelium (RPE).

Bilateral presentation of an acute RRD at the exact same time is relatively rare and often associated with specific risk factors:

• Severe head or ocular trauma

• Syndromic conditions (e.g., Stickler syndrome, Marfan syndrome)

• Extreme bilateral high myopia

• Bilateral prior intraocular surgeries (aphakia/pseudophakia)

• Giant retinal tear (GRT) in the fellow eye

Note

Bilateral detachments often require simultaneous or rapidly sequential bilateral vitreo-retinal surgeries and are considered a major ophthalmologic surgical emergency to prevent irreversible bilateral blindness.

✅ Includes

The following clinical scenarios and terms map to H33.003 when bilateral:

• Bilateral rhegmatogenous retinal detachment (NOS)

• Bilateral primary retinal detachment with break

• Retinal detachment with hole/tear, bilateral (type unspecified)

❌ Excludes

Excludes1 — Cannot be coded together

The Excludes1 note dictates that the following conditions cannot be coded alongside H33.003. They represent different pathophysiologic mechanisms of retinal separation:1

• Serous retinal detachment (H33.2-) — Fluid accumulation without a break (e.g., exudative)

• Tractional retinal detachment (H33.4-) — Fibrovascular bands pulling the retina (e.g., advanced diabetic retinopathy)

• Retinal detachment with unspecified etiology (H33.5-)

Excludes2 — Can be coded together if both are present

• Diabetic retinopathy with traction retinal detachment (E08.35-, E09.35-, E10.35-, E11.35-, E13.35-)

• Note: If a patient has a combined traction-rhegmatogenous retinal detachment (TRD/RRD), you may code the diabetic tractional detachment alongside the rhegmatogenous code to capture the complex mixed etiology.

🛠️ CPT Procedural Crosswalk — wRVU & Assistant Payable Status

Surgical repair of a rhegmatogenous retinal detachment is highly complex. Below are the most common procedural CPT codes paired with H33.003.²

CPT Code	Description	wRVU (Facility)	Asst. Surgeon Payable?	Co-Surgeon Payable?
67108	Repair of retinal detachment; with vitrectomy, any method, including endolaser, cryotherapy, subretinal fluid drainage, scleral buckling, +/- lens removal	24.50	Yes (Indicator 2) — Justification required	No (Indicator 0)
67107	Repair of retinal detachment; scleral buckling (such as lamellar scleral dissection, imbrication or encircling procedure)	19.33	Yes (Indicator 2) — Justification required	No (Indicator 0)
67110	Repair of retinal detachment; by injection of air or other gas (e.g., pneumatic retinopexy)	10.75	No (Indicator 0)	No (Indicator 0)
67145	Prophylaxis of retinal detachment (e.g., retinal break, tear) without detachment, photocoagulation	6.00	No (Indicator 0)	No (Indicator 0)
76512	Ophthalmic ultrasound, diagnostic; B-scan	0.45	No (Indicator 0)	No (Indicator 0)

Note: wRVU values are estimates based on the standard CMS Physician Fee Schedule. Check current year exact values.

💊 Coding Scenarios

Scenario 1 — Simultaneous Bilateral Vitrectomy for RRD (OR Setting)

Clinical Vignette: A 28-year-old male with a history of severe myopia and previous ocular trauma presents to the ER with a “dark curtain” over his vision in both eyes that started 12 hours ago. Dilated fundus exam reveals bilateral “macula-off” rhegmatogenous retinal detachments. The specific type/number of retinal tears is obscured by mild vitreous hemorrhage, but subretinal fluid tracking from peripheral breaks is evident. He is taken emergently to the OR for simultaneous bilateral pars plana vitrectomy with endolaser, subretinal fluid drainage, and SF6 gas tamponade.

CPT / HCPCS:

• 67108-50 — Repair of retinal detachment with vitrectomy, bilateral (Note: Some payers require 67108-RT and 67108-LT-50 or -59; check payer preference for major bilateral surgeries)

• 0346T — OCT imaging of the retina during surgery (if utilized and documented)

ICD-10-CM:

• H33.003 — Unspecified retinal detachment with retinal break, bilateral (Bilateral code captures both eyes; “unspecified” used because the exact break count was obscured initially)

• H44.2A3 — Degenerative myopia with choroidal neovascularization/complications, bilateral (Capturing the high myopia risk factor)

Scenario 2 — ER Evaluation and B-Scan Diagnosis

Clinical Vignette: A 60-year-old female presents to the Emergency Department complaining of flashing lights and sudden severe vision loss in both eyes over the past 48 hours. Due to dense bilateral cataracts, the ER physician cannot visualize the retina with direct ophthalmoscopy. A bilateral B-scan ultrasound is performed, showing large V-shaped membranous elevations attaching at the optic nerve and ora serrata in both eyes, confirming bilateral rhegmatogenous retinal detachments. She is transferred to a tertiary care retinal center.

CPT / HCPCS:

• 99285 — Emergency department visit, high complexity

• 76512 — Ophthalmic ultrasound, B-scan, bilateral (modifier -26 if billing professional component only)

ICD-10-CM:

• H33.003 — Unspecified retinal detachment with retinal break, bilateral (Correct because the B-scan confirms RRD, but cannot specify the exact number or type of breaks)

• H25.813 — Combined forms of age-related cataract, bilateral (Explains the obscured view)

Scenario 3 — CDI Query: Specifying the Break

Clinical Vignette: The surgeon’s operative note lists the post-operative diagnosis as “Bilateral Rhegmatogenous Retinal Detachment.” In the body of the operative report, the surgeon details repairing a single horseshoe tear at 12 o’clock in the right eye, and multiple small atrophic holes in the superior quadrant of the left eye.

Action / Outcome:

If the coder simply codes from the header, they would select H33.003 (Unspecified break, bilateral). However, the body of the report specifies the breaks are different in each eye. A bilateral code cannot be used if the eyes are at different stages or have different subtypes.

Corrected ICD-10-CM Coding (Instead of H33.003):

• H33.011 — Retinal detachment with single break, right eye

• H33.022 — Retinal detachment with multiple breaks, left eye

⚠️ Coding Pitfalls and Tips

	Pitfall or Tip
❌	Do not default to H33.003 if breaks are specified: As shown in Scenario 3, if the physician documents a single break, multiple breaks, giant tear, or dialysis, you must use the codes from the H33.01-, H33.02-, H33.03-, or H33.04- families instead of H33.00-.
❌	Do not use a bilateral code if the break types differ between eyes: If the right eye has a single break and the left has multiple breaks, you must use two separate unilateral codes. H33.003 implies the exact same (unspecified) condition exists in both eyes.
❌	Do not code H33.003 for a simple retinal tear without detachment: If the patient only has a retinal break/tear (and no subretinal fluid/detachment), use the H33.3- series (Retinal breaks without detachment).
✅	Bill B-Scans appropriately: B-scan (76512) is standard when media opacities (hemorrhage, cataract) prevent direct visualization of the detachment.
✅	Use modifier 50 or RT/LT correctly for surgery: When a major vitreo-retinal procedure like 67108 is performed bilaterally, follow strict payer guidelines for bilateral modifier billing to avoid 50% denial of the second eye.
