ICD-10 Code H52.11: Myopia, right eye

Key Takeaways

ICD-10 Code H52.11 is the billable, laterality-specific code for myopia in the right eye, valid for FY 2026.

H52.1 (parent code) is non-billable; always use H52.11, H52.12, or H52.13 to specify laterality.

H52.11 maps to ICD-9-CM 367.1 and is commonly billed alongside routine eye exam CPT codes 92002, 92004, 92012, and 92014.

Pabau’s claims management software helps optometry and ophthalmology practices attach the correct laterality-specific diagnosis codes to every claim.

ICD-10 Code H52.11 is the billable, laterality-specific code for myopia in the right eye. It replaces the non-billable parent code H52.1, which payers reject because it doesn’t specify which eye is affected. This guide covers the H52.11 definition, laterality rules, related codes, documentation requirements, and the CPT codes billed alongside it in optometry and ophthalmology practices.

Myopia affects roughly 30% of the US population, and that figure is rising. Optometrists and ophthalmologists submitting claims under Chapter 7 (Diseases of the Eye and Adnexa, H00-H59) need to code with precision.

Under ICD-10-CM, laterality is not optional. Payers, including Medicare and commercial insurers, reject claims coded to the non-specific parent when a specific code exists. The guidance below is grounded in CMS ICD-10 coding requirements and reflects FY 2026 code validity.

ICD-10 Code H52.11: Definition and clinical description

ICD-10 Code H52.11 describes myopia of the right eye. Myopia, commonly called nearsightedness, is a refractive error in which the eyeball is too long or the cornea has too much curvature, causing light to focus in front of the retina rather than directly on it. The result: distant objects appear blurred while near objects remain clear.

H52.11 sits within the H52 category (Disorders of refraction and accommodation) under Block H49-H52 (Disorders of ocular muscles, binocular movement, accommodation, and refraction), itself part of Chapter 7 (H00-H59) of the WHO ICD-10 classification. The United States uses the ICD-10-CM clinical modification maintained by the CDC/NCHS ICD-10-CM coding tool.

The AAPC Codify ICD-10-CM lookup and other commercial tools confirm H52.11 as a valid, billable code for FY 2016 through FY 2026. No excludes notes or coding restrictions apply to H52.11 itself. It is also distinct from ICD-10-CM codes covering degenerative myopia (H44.2x series), which involve structural pathology rather than straightforward refractive error.

An optometry practice using claims management software can map H52.11 directly to right-eye myopia encounters and reduce the chance of a non-specific code error reaching the payer.

Laterality rules: When to use H52.11 vs H52.10, H52.12, and H52.13

ICD-10-CM introduced mandatory laterality in 2015. For myopia, this means you must report the eye (or eyes) affected. Submitting H52.1, the parent code, is never acceptable for a claim that requires a billable code. Payers return these as non-specific.

The laterality distinction matters beyond denial risk. Accurate laterality documentation supports continuity of care, particularly when a patient progresses from unilateral myopia to bilateral involvement over successive visits.

Coders frequently encounter exam notes that record findings for each eye separately. In those cases, H52.11 applies to the right eye and H52.12 to the left, both on the same claim if the patient has bilateral refractive errors documented individually.

Other codes in the H49-H52 block follow the same laterality pattern. H49.12, for fourth trochlear nerve palsy in the left eye, requires the same eye-specific documentation as H52.11.

Documentation requirements for H52.11

A claim submitted under H52.11 requires clinical documentation that explicitly identifies myopia in the right eye. Vague chart notes that record only “myopia” without laterality trigger audit flags, since the note doesn’t match the specificity the code requires.

• Visual acuity measurement: Distance visual acuity for the right eye, recorded with and without correction (e.g., OD 20/200 uncorrected, 20/20 corrected).
• Refraction data: Subjective or objective refraction results for the right eye, documented with sphere, cylinder, and axis values.
• Diagnostic impression: The provider’s assessment must explicitly note myopia in the right eye, not just a general refractive error.
• Laterality language: Phrases such as “right eye myopia,” “myopia OD,” or “myopia, right eye” in the assessment section are sufficient. Abbreviation “OD” (oculus dexter) is widely understood but spell it out in the diagnosis line to eliminate ambiguity.
• Severity or degree: Not required for H52.11 coding, but noting mild, moderate, or high myopia supports clinical context and payer review if prior authorization applies.

Practices that use structured patient record management systems with laterality-specific fields in their exam templates catch missing laterality before the claim reaches the billing team. A PERRLA eye exam template that separates OD and OS findings and prompts an explicit diagnosis statement for each eye is the most reliable preventive measure.

For practices managing a high volume of refraction encounters, the documentation workflow matters as much as the coding itself. Clinical documentation software that flags missing laterality fields before submission catches these errors earlier than a manual chart review.

The same specificity requirement applies elsewhere in ICD-10-CM. H40.9 and other eye codes require the same level of anatomical and laterality detail before a claim is billable.

CPT codes commonly billed with ICD-10 Code H52.11

H52.11 is a diagnosis code, not a procedure code. Every claim that uses H52.11 also needs one or more CPT procedure codes that describe what the provider did during the visit. The following CPT codes appear most frequently alongside myopia codes in optometry and ophthalmology billing.

Medicare and most commercial plans cover these ophthalmological service codes when myopia results in functional impairment or requires active management. Routine refraction, billed under 92015, isn’t covered by Medicare as a standalone benefit, though many commercial vision plans and supplemental insurance products do cover it.

Payers often split a medical eye exam from a routine vision exam, and each runs through a different benefit. That split determines how H52.11 is billed and where the claim goes. Practices managing this split benefit from digital intake forms that capture insurance details for both benefits at registration.

HCPCS vision materials codes, known as V-codes, may also appear on claims alongside H52.11 when eyeglasses or contact lenses are prescribed. These are billed through the vision benefit, not the medical benefit, and require separate handling. V2103, for a single-vision spherocylinder lens, is a common example billed this way.

Related ICD-10-CM codes in the H52 refraction category

Myopia is one of several refractive errors classified under H52. Knowing the surrounding codes helps coders select the most accurate option and avoid the most common substitution errors.

Astigmatism and myopia can be reported together on the same claim when both conditions are documented and treated in the same encounter. Payers don’t treat this as duplicate or unbundled billing, since the codes reflect separate refractive conditions.

If a patient has myopic astigmatism, code H52.11 for the right eye alongside the appropriate astigmatism code. List H52.11 as the primary diagnosis when myopia is the presenting reason for the visit.

Compliance management tools built into the EHR help practices apply these dual-coding conventions consistently, rather than relying on individual coder memory. That kind of automation is one of several time-saving practice features that cut manual review at growing practices.

Billing workflow tips for optometry and ophthalmology practices

Claims denial patterns for refraction codes are predictable, which makes them preventable. Three workflow steps address the majority of H52.11-related rejections.

• Template-level laterality prompts: Build laterality fields (OD/OS/OU) into every refraction exam template in your EHR or practice management system. If the template captures laterality at the point of documentation, the coder does not have to interpret chart notes after the fact.
• Benefit routing at registration: Identify whether the patient has a medical benefit, a vision benefit, or both before the visit. This determines whether H52.11 is billed to the medical carrier (for a medical eye exam) or the vision plan (for a routine exam).
• Payer-specific coverage verification: Prior authorization requirements for services billed with H52.11 vary by payer and plan. Check coverage before the encounter for new patients and annually for established patients whose plans may have changed.

The ICD-10 Data lookup confirms H52.1 as non-billable and directs coders to the laterality-specific child codes. Keeping a reference like this at the coding workstation helps newer staff avoid the parent-code error.

Patient compliance workflows built into the EHR can flag encounters where the exam note doesn’t match a billable laterality code before the claim is submitted. The same logic applies to codes like H50.9, where missing laterality causes the same kind of rejection.

Practice management software with specialty-specific templates is one of the most practical investments a growing practice can make. It also supports the broader revenue cycle, since clean claims move faster from submission to payment.

Conclusion

Most myopia coding errors trace back to incomplete documentation, not the billing step itself. When the clinical note clearly identifies right-eye myopia using laterality-specific language, H52.11 maps cleanly to the diagnosis, the CPT codes align, and the claim moves through without manual intervention.
