H18.51-H18.519Primary Range

Fuchs' endothelial dystrophy

This range includes codes for Fuchs dystrophy with specification for laterality.

Fuchs' heterochromic cyclitis

This code is for a related but distinct condition involving chronic anterior uveitis.

CodeDescriptionWhen to UseKey Documentation
H18.511Fuchs' endothelial dystrophy, right eyeUse when Fuchs dystrophy is confirmed in the right eye with clinical findings.
  • Specular microscopy showing guttae
  • Endothelial cell count <1000 cells/mm²
H18.513Fuchs' endothelial dystrophy, bilateralUse when Fuchs dystrophy is confirmed in both eyes.
  • Bilateral guttae on slit lamp exam
  • Morning blurring resolving by midday

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 Fuchs dystrophy

Essential facts and insights about Fuchs Dystrophy

The ICD-10 code for Fuchs dystrophy is H18.51-, with specific codes for laterality: H18.511 for right eye, H18.512 for left eye, and H18.513 for bilateral.

Billable Code

Decision Criteria

clinical Criteria

  • Presence of guttae and reduced endothelial cell count

Applicable To

  • Fuchs' dystrophy affecting the right eye

Excludes

  • Fuchs' heterochromic cyclitis (H20.819)

Clinical Validation Requirements

  • Specular microscopy showing guttae
  • Endothelial cell count <1000 cells/mm²

Code-Specific Risks

  • Incorrect laterality documentation

Coding Notes

  • Ensure laterality is documented to avoid unspecified coding.

Ancillary Codes

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

Corneal edema

H18.22
Use when corneal edema is present with pachymetry >640 µm.

Age-related cataract

H25.1
Use when cataracts are present and related to the condition.

Differential Codes

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

Other hereditary corneal dystrophies

H18.59
Use when Fuchs cannot be confirmed and other dystrophies are suspected.

Bullous keratopathy

H18.23
Use if pseudophakic/aphakic etiology is confirmed.

Documentation & Coding Risks

Avoid these common documentation and coding issues when documenting Fuchs Dystrophy to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code H18.511.

Impact

Clinical: Inaccurate treatment planning, Regulatory: Non-compliance with coding standards, Financial: Potential claim denials

Mitigation Strategy

Use documentation templates, Regular training on coding updates

Impact

Reimbursement: May lead to claim denials due to lack of specificity., Compliance: Non-compliance with coding guidelines., Data Quality: Reduces accuracy of clinical data.

Mitigation Strategy

Always specify laterality using H18.51- codes.

Impact

Failure to document laterality can lead to audits.

Mitigation Strategy

Implement mandatory fields in EHR for laterality.

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.

Ophthalmology Progress Note

Specialty: Ophthalmology

Required Elements

  • Subjective symptoms
  • Objective findings
  • Assessment
  • Plan

Example Documentation

**Subjective**: Reports morning blurring worsening over 6 months. **Objective**: VA: 20/40 OD, 20/50 OS. Slit Lamp: Central guttae OD, OS. Pachymetry: 650 µm OD. **Assessment**: Stage II Fuchs dystrophy OU. **Plan**: Hypertonic saline.

Examples: Poor vs. Good Documentation

Poor Documentation Example
Patient has Fuchs dystrophy.
Good Documentation Example
Stage II Fuchs endothelial corneal dystrophy OU with non-confluent central guttae, pachymetry 590 µm OU, glare testing positive bilaterally.
Explanation
The good example provides specific findings and laterality, enhancing clinical detail and coding accuracy.
