Short description
Age-related nuclear cataract right eye — senile/age-related opacification of the lens nucleus in the right eye causing visual impairment; code H25.11 when documentation specifies nuclear cataract and right laterality.
Full description
Definition
Age-related nuclear cataract is a degenerative opacity of the central (nuclear) portion of the lens that typically progresses with aging and produces decreased distance vision, glare, and color desaturation. H25.11 is the ICD-10-CM code for age-related nuclear cataract, right eye and is a billable/specific code when laterality and subtype (nuclear) are documented.
Clinical features to document
- Symptoms: progressive blurred distance vision, increased glare/halos, difficulty with night driving, faded colors.
- Exam findings: decreased best-corrected visual acuity, lens nuclear sclerosis on slit-lamp exam, red reflex changes.
- Diagnostics: visual acuity, slit-lamp biomicroscopy, dilated fundus exam, ocular history (impact on activities of daily living).
- Treatment: conservative measures (lighting, refractive correction) or cataract extraction with intraocular lens when visual function is impaired and patient elects surgery.
HCC and risk adjustment
HCC status
- H25.11 is not an HCC. Age-related cataract is an acute/chronic ocular diagnosis but does not map to CMS chronic condition HCC categories used for prospective risk adjustment. Code chronic systemic conditions (for example, diabetes with ophthalmic manifestations) separately when present.
wRVU and RVU information
Key point
- Diagnosis codes do not carry wRVU or RVU values. Physician work RVUs and total RVUs are assigned to CPT procedure and evaluation codes (for example, cataract surgery CPTs, ophthalmic preoperative visits, and postoperative global services). Select CPTs that reflect the actual services performed; those CPTs determine wRVU capture and reimbursement.
Variations laterality and related ICD-10 codes
Related H25 codes
| Code | Description |
|---|---|
| H25.10 | Age-related nuclear cataract unspecified eye |
| H25.11 | Age-related nuclear cataract right eye |
| H25.12 | Age-related nuclear cataract left eye |
| H25.13 | Age-related nuclear cataract bilateral |
| H25.8 | Other age-related cataract |
| H25.9 | Age-related cataract unspecified |
Coding guidance
- Use the laterality-specific code when the chart documents right, left, or bilateral. If the record lacks laterality, use the unspecified-eye code. If the cataract subtype is different (cortical, posterior subcapsular, mixed), use the appropriate H25 subcode.
Sample CPT and ICD-10-CM codes commonly used with H25.11
| Type | Code | Description |
|---|---|---|
| ICD-10-CM | H25.11 | Age-related nuclear cataract right eye |
| ICD-10-CM | H25.12 | Age-related nuclear cataract left eye |
| CPT | 66984 | Extracapsular cataract removal with insertion of intraocular lens (standard) |
| CPT | 66982 | Complex cataract surgery (e.g., with complications) |
| CPT | 92002 / 92004 | Ophthalmological new patient exam (office/clinic) |
| CPT | 92012 / 92014 | Ophthalmological established patient exam |
| HCPCS | V2780 | Intraocular lens (example device coding varies by lens type) |
Notes
- Choose the CPT that matches the documented surgical technique and complexity. Preoperative and postoperative visits are often bundled into the global surgical package; verify global period rules and modifier use for separate E/M billing. Confirm device-specific HCPCS when billing for premium or toric IOLs.
DRG and inpatient grouping
MS-DRG considerations
- cataract surgery is typically an outpatient procedure; inpatient DRG grouping is uncommon for routine cataract extraction. If inpatient admission occurs for ocular surgery with complications, facility grouping depends on principal diagnosis, procedures, and presence of major complications or comorbidities.
Documentation and sequencing guidance checklist
- Explicit diagnosis: document “age-related nuclear cataract, right eye” to support H25.11.
- Specify subtype and laterality: nuclear vs cortical vs posterior subcapsular; right/left/bilateral.
- Document functional impact: visual acuity, effect on driving/reading, failed conservative measures.
- Document surgical decision-making: indication for cataract extraction, informed consent, planned IOL type (monofocal, toric, multifocal).
- Record perioperative details: laterality, technique, complications, and postoperative visual outcomes.
- If systemic disease affects eye: code systemic conditions (e.g., diabetes mellitus with ophthalmic complications) separately.
Clinical pearls
- Presentation: nuclear cataracts often cause early loss of distance vision and improved near vision (second sight) initially, then progressive decline and glare sensitivity.
- Surgical timing: base decision on functional impairment and patient goals rather than lens appearance alone.
- IOL selection: document lens choice and medical necessity for premium lenses; device coding may require HCPCS and documentation of patient consent and counseling.
Billing pitfalls to avoid
- Not documenting laterality or subtype — leads to unspecified codes and potential denials.
- Billing separate E/M during global period without modifier — postoperative visits included in global surgical package unless a separate, unrelated E/M is clearly documented and modifier -25 is justified.
- Omitting device coding — premium IOLs require appropriate HCPCS and patient cost-sharing documentation.
- Failing to code comorbid ocular/systemic conditions that affect management or risk.
Example documentation template for charting
Assessment
- Primary: Age-related nuclear cataract, right eye — ICD-10: H25.11.
- Symptoms: Progressive decreased distance vision OD for [duration]; glare and difficulty driving at night.
- Exam: BCVA OD [value]; slit-lamp: nuclear sclerosis grade [value]; red reflex diminished OD.
- Impact: Difficulty driving and reading street signs; refractive correction no longer adequate.
Plan
- Discuss cataract extraction with intraocular lens implantation OD; patient counseled on risks/benefits and IOL options (monofocal vs toric vs multifocal).
- Order preoperative testing and schedule surgery; document laterality and planned CPT (e.g., 66984).
- Postoperative follow-up at day 1, week 1, and month 1; document any complications.
Quick reference cheat-sheet
- Primary diagnosis code: H25.11 for age-related nuclear cataract right eye.
- If left eye: H25.12; bilateral: H25.13; unspecified: H25.10.
- Surgery CPT examples: 66984 standard cataract extraction with IOL; 66982 complex cases.
- Diagnosis codes do not carry RVUs; select CPTs for wRVU capture.
