H52.0-Primary Range

Disorders of refraction and accommodation

Emmetropia is categorized under disorders of refraction, representing the normal refractive state.

Encounter for examination of eyes and vision

Used for routine eye exams where emmetropia might be documented.

Key Information: ICD-10 code for emmetropia

Essential facts and insights about Emmetropia

The ICD-10 code for emmetropia is H52.0-, representing the normal refractive state.

Primary ICD-10-CM Code for emmetropia

Emmetropia
Non-billable Code

Decision Criteria

clinical Criteria

  • Visual acuity 20/20 and plano refraction

coding Criteria

  • Do not use as primary code for routine exams

Applicable To

  • Normal refractive state

Excludes

Clinical Validation Requirements

  • Visual acuity 20/20
  • Cycloplegic refraction confirms plano
  • Corneal topography shows neutral spherical equivalent

Code-Specific Risks

  • Incorrectly coding as a primary diagnosis for routine exams.

Coding Notes

  • Emmetropia is rarely coded unless specifically relevant to the clinical encounter.

Ancillary Codes

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

Encounter for examination of eyes and vision without abnormal findings

Z01.00
Use for routine exams confirming emmetropia without active management.

Post-procedural status

Z98.89
Use for documenting post-surgical emmetropia.

Differential Codes

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

Myopia

H52.1-
Presence of refractive error: -3.00 DS OU

Hyperopia

H52.0-
Presence of refractive error: +2.50 DS OU

Astigmatism

H52.20-
Corneal topography shows 2.5D cylinder

Documentation & Coding Risks

Avoid these common documentation and coding issues when documenting Emmetropia to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code H52.0-.

Impact

Clinical: May lead to misinterpretation of patient status., Regulatory: Non-compliance with documentation standards., Financial: Potential for denied claims due to insufficient documentation.

Mitigation Strategy

Include specific visual acuity and refraction results.

Impact

Reimbursement: May lead to denied claims if used incorrectly., Compliance: Non-compliance with coding guidelines., Data Quality: Inaccurate representation of patient data.

Mitigation Strategy

Use Z01.00 unless emmetropia is an explicit outcome.

Impact

Incorrectly coding routine exams as emmetropia.

Mitigation Strategy

Use Z01.00 for routine exams unless emmetropia is specifically documented.

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.

Frequently Asked Questions

Common questions about ICD-10 coding for Emmetropia, with expert answers to help guide accurate code selection and documentation.

Documentation Templates for Emmetropia

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

Post-LASIK emmetropia confirmation

Specialty: Ophthalmology

Required Elements

  • Visual Acuity
  • Refraction
  • Corneal Topography

Example Documentation

Visual Acuity: UCVA 20/20 OD, 20/20 OS Refraction: Plano OU Corneal Topography: Central Ks 43.25D OD, 43.00D OS; no irregular astigmatism Assessment: Successful emmetropia (H52.03) post refractive lens exchange (Z98.89)

Examples: Poor vs. Good Documentation

Poor Documentation Example
Vision normal
Good Documentation Example
Post-LASIK emmetropia confirmed: UCVA 20/20 OU, manifest refraction +0.00 DS OU, corneal topography central 0.5mm zone within ±0.25D
Explanation
The good example provides specific clinical findings supporting the diagnosis.
