Quick Answers
What is ICD-10 code H52.03, and is it billable?
H52.03 is the ICD-10-CM diagnosis code for bilateral hypermetropia, the clinical term for farsightedness affecting both eyes. It is a complete, billable code valid for HIPAA-covered transactions, so you do not need to add further characters. Do not report the category header H52.0 on a claim, since that header is not billable on its own.
Why do H52.03 claims get denied?
The most common avoidable denial is a laterality mismatch: reporting H52.00 (unspecified eye) when the chart documents both eyes and supports H52.03 (bilateral). Payers increasingly treat unspecified laterality as a signal the chart was not fully reviewed. Other frequent causes are refraction billed to a payer that does not cover it, or the claim routed to the wrong plan
How does refraction and plan routing affect getting H52.03 paid?
H52.03 almost always pairs with the refractive-state determination reported under CPT 92015, and many payers, including Medicare in most situations, treat refraction as a non-covered service that is the patient’s financial responsibility. A refractive error like bilateral hypermetropia frequently belongs on the patient’s vision plan rather than their medical plan, and misrouting it to the medical carrier causes silent denials. Getting the medical-versus-vision split right is a meaningful share of monthly collections.
H52.03 is the ICD-10-CM diagnosis code for bilateral hypermetropia, the clinical term for farsightedness affecting both eyes. It is a valid, billable code for HIPAA-covered transactions. The coding is simple. Getting it paid cleanly is where ophthalmology practices lose money.
Most code-lookup pages stop at that definition. If you bill for an ophthalmology practice, the definition was never your problem. The denials are. This guide covers what the lookup sites skip: the laterality error that triggers rejections, the refraction service that surprises patients, and the plan-routing decision that quietly drains revenue.
What ICD-10 Code H52.03 Means
Hypermetropia, also called hyperopia or farsightedness, is a refractive error where the eye focuses images behind the retina instead of on it. Distant objects are usually clearer than near ones. H52.03 specifies that the condition is present in both eyes.
The code sits in Chapter 7 of ICD-10-CM (Diseases of the eye and adnexa), under category H52, Disorders of refraction and accommodation.
Is H52.03 billable?
Yes. H52.03 is a complete, billable code valid for HIPAA-covered transactions. You do not need to add further characters, and you should not report the category header H52.0 on a claim, because that header is not billable on its own.
The H52.0 Laterality Family and the Denial It Causes
H52.03 is one of four members in the hypermetropia family, and choosing the wrong one is the single most common avoidable denial in this code set:
- H52.00, hypermetropia, unspecified eye
- H52.01, hypermetropia, right eye
- H52.02, hypermetropia, left eye
- H52.03, hypermetropia, bilateral
Why “unspecified eye” gets your claim flagged
When a coder is moving fast, H52.00 is the path of least resistance. It is also the code most likely to draw a denial or a documentation request. Payers increasingly treat unspecified laterality codes as a signal that the chart was not fully reviewed, especially when the encounter clearly documents both eyes. A refraction performed on both eyes supports H52.03, not H52.00. Reporting “unspecified” when the record supports “bilateral” is not a shortcut. It is a rejected claim and a rework cycle.
The fix is procedural, not clinical: laterality should be pulled from the documented exam on every claim, and “unspecified” should be reserved for the rare case where the record genuinely does not state it.
If laterality denials are showing up in your ophthalmology aging report, the problem is usually the billing workflow, not the codes.

Getting H52.03 Paid: Documentation and Pairing
What the chart must support
To defend H52.03, the encounter should document the refractive finding in both eyes. Diagnosis codes ride on the strength of the note. If the exam supports bilateral, the claim should say bilateral, and the documentation should back it without the coder having to guess.
Refraction and the coverage surprise (CPT 92015)
H52.03 rarely appears alone. It almost always pairs with the refractive-state determination reported under CPT 92015. Here is the part that catches practices off guard: many payers, including Medicare in most situations, treat refraction as a non-covered service that is the patient’s financial responsibility. If the front desk does not flag this before the visit, the practice either writes off the charge or sends a surprise bill. Neither outcome is acceptable. A clean workflow collects for refraction at the point of service where the payer allows it, with the appropriate patient notice on file.
Medical plan versus vision plan routing
A refractive error like bilateral hypermetropia frequently belongs on the patient’s vision plan rather than their medical plan, and the correct destination depends on the payer, the plan, and the reason for the visit. Misrouting H52.03 to the medical carrier when it should have gone to the vision plan is a silent leak: the claim denies, nobody catches it, and the revenue never arrives. For practices running both medical eye care and routine vision services, getting this split right is a meaningful share of monthly collections.
Frequently asked questions
Medicare may accept H52.03 as a diagnosis, but the associated refraction (CPT 92015) is generally not a covered Medicare benefit and is billed to the patient. Coverage of any related diagnostic testing depends on medical necessity and the specific contractor.
Yes. It can stand as the primary diagnosis for a refractive-error encounter. Whether it should be primary on a given claim depends on the reason for the visit and any other conditions documented in the chart.
Hypermetropia (H52.0x) is farsightedness. Myopia (H52.1x) is nearsightedness. They are separate categories, so confirm the documented diagnosis before selecting the family and the laterality.
The usual causes are laterality mismatches (reporting unspecified when the chart supports bilateral), refraction billed to a payer that does not cover it, or the claim routed to the wrong plan. If you are also coding diagnostic imaging during these visits, our breakdown of CPT code 92134 covers the documentation those services require.
Bilateral hypermetropia is easy to code and easy to underbill.
