Compare key differences between these codes to ensure accurate selection

CodeDescriptionWhen to UseKey Documentation
H25.03Age-related nuclear cataract, bilateralUse when documenting bilateral age-related nuclear cataracts with appropriate clinical findings.
  • LOCS III grading ≥3.0
  • Glare testing ≥5.0 log units
  • BCVA ≤20/40 OU
H26.33Drug-induced cataract, bilateralUse when cataracts are linked to drug use, such as long-term steroid use.
  • Medication list showing ≥1 year of glucocorticoids
  • Absence of other risk factors

Clinical Decision Support

Always review the patient's clinical documentation thoroughly. When in doubt, choose the more specific code and ensure documentation supports it.

Key Information: ICD-10 code for bilateral cataracts

Essential facts and insights about Bilateral Cataracts

The ICD-10 code for bilateral age-related nuclear cataracts is H25.03, while H26.33 is used for drug-induced cases.

Primary ICD-10-CM Codes for cataracts bilateral

Age-related nuclear cataract, bilateral
Non-billable Code

Decision Criteria

clinical Criteria

  • Presence of bilateral nuclear cataracts with significant visual impairment.

Applicable To

  • Bilateral age-related nuclear cataracts

Excludes

Clinical Validation Requirements

  • LOCS III grading ≥3.0
  • Glare testing ≥5.0 log units
  • BCVA ≤20/40 OU

Code-Specific Risks

  • Ensure bilateral status is documented; otherwise, use unilateral codes.

Coding Notes

  • Ensure to update the code from bilateral to unilateral after the first eye surgery.

Ancillary Codes

Additional codes that should be used in conjunction with the main diagnosis codes when applicable.

Cataract extraction status

Z98.41
Use after cataract surgery to indicate the status of the treated eye.

Differential Codes

Alternative codes to consider when ruling out similar conditions to the primary diagnosis.

Age-related cortical cataract, bilateral

H25.13
Use when cataracts are primarily cortical rather than nuclear.

Unspecified cataract

H26.9
Use only when the type of cataract is not specified.

Documentation & Coding Risks

Avoid these common documentation and coding issues when documenting Bilateral Cataracts to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code H25.03.

Impact

Clinical: Misrepresents patient's current clinical status., Regulatory: Non-compliance with coding guidelines., Financial: Potential for claim denials.

Mitigation Strategy

Review and update codes post-surgery.

Impact

Reimbursement: May lead to claim denials or reduced payments., Compliance: Non-compliance with specificity requirements., Data Quality: Reduces accuracy of clinical data.

Mitigation Strategy

Use specific bilateral codes like H25.03 or H26.33 based on etiology.

Impact

Incorrect use of -50 modifier for bilateral procedures.

Mitigation Strategy

Use RT/LT modifiers as per CMS guidelines.

Documentation errors, coding pitfalls, and audit risks are interconnected aspects of medical coding and billing. Addressing all three areas helps ensure accurate coding, optimal reimbursement, and regulatory compliance.

Documentation Templates for Bilateral Cataracts

Use these documentation templates to ensure complete and accurate documentation for Bilateral Cataracts. These templates include all required elements for proper coding and billing.

Bilateral Cataract Surgery

Specialty: Ophthalmology

Required Elements

  • Visual acuity measurements
  • Slit lamp findings
  • Functional impact on ADLs
  • Surgical plan

Example Documentation

Visual Acuity: 20/70 OD, 20/80 OS. Slit Lamp: 3+ nuclear sclerotic changes OU. Plan: Phacoemulsification OU planned sequentially.

Examples: Poor vs. Good Documentation

Poor Documentation Example
Cataracts present bilaterally.
Good Documentation Example
Best-corrected visual acuity 20/50 OU interfering with driving and reading.
Explanation
The good example provides specific visual acuity and functional impact, supporting medical necessity.
