H16.299 - Other keratoconjunctivitis, unspecified eye
| ICD-10: | H16.299 |
| Short Description: | Other keratoconjunctivitis, unspecified eye |
| Long Description: | Other keratoconjunctivitis, unspecified eye |
| Status: | Valid for Submission |
| Version: | ICD-10-CM 2022 |
| Code Classification: |
H16.299 is a billable ICD-10 code used to specify a medical diagnosis of other keratoconjunctivitis, unspecified eye. The code is valid during the fiscal year 2022 from October 01, 2021 through September 30, 2022 for the submission of HIPAA-covered transactions.
This code might also be used to specify conditions or terms like atopic keratoconjunctivitis, conjunctivitis caused by drug, dendriform epithelial keratoconjunctivitis, diffuse inflammation of orbit, diffuse stromal keratoconjunctivitis , disease due to moraxella, etc.
Unspecified diagnosis codes like H16.299 are acceptable when clinical information is unknown or not available about a particular condition. Although a more specific code is preferable, unspecified codes should be used when such codes most accurately reflect what is known about a patient's condition. Specific diagnosis codes should not be used if not supported by the patient's medical record.
Approximate Synonyms
The following clinical terms are approximate synonyms or lay terms that might be used to identify the correct diagnosis code:
- Atopic keratoconjunctivitis
- Conjunctivitis caused by drug
- Dendriform epithelial keratoconjunctivitis
- Diffuse inflammation of orbit
- Diffuse stromal keratoconjunctivitis
- Disease due to Moraxella
- Drug-induced disorder of cornea
- Drug-induced keratoconjunctivitis
- Drug-induced mucositis
- Keratoconjunctivitis due to Moraxella bovis
- Keratoconjunctivitis nodosa
- Microsporidia keratoconjunctivitis
- Superior limbic keratoconjunctivitis
- Toxic keratoconjunctivitis
- Toxic keratoconjunctivitis
- Vernal conjunctivitis
- Vernal keratoconjunctivitis
Diagnostic Related Groups - MS-DRG Mapping
The is diagnosis code is grouped in the following groups for version MS-DRG V39.0 What are Diagnostic Related Groups?
The Diagnostic Related Groups (DRGs) are a patient classification scheme which provides a means of relating the type of patients a hospital treats. The DRGs divides all possible principal diagnoses into mutually exclusive principal diagnosis areas referred to as Major Diagnostic Categories (MDC). applicable from 10/01/2021 through 09/30/2022.
| MS-DRG | MS-DRG Title | MCD | Relative Weight |
|---|---|---|---|
| 124 | OTHER DISORDERS OF THE EYE WITH MCC | 02 | 1.3988 |
| 125 | OTHER DISORDERS OF THE EYE WITHOUT MCC | 02 | 0.8354 |
The relative weight of a diagnostic related group determines the reimbursement rate based on the severity of a patient's illness and the associated cost of care during hospitalization.
Convert to ICD-9 Code
The General Equivalency Mapping (GEM) crosswalk indicates an approximate mapping between the ICD-10 code H16.299 its ICD-9 equivalent. The approximate mapping means there is not an exact match between the ICD-10 code and the ICD-9 code and the mapped code is not a precise representation of the original code.
Patient Education
Corneal Disorders
Your cornea is the outermost layer of your eye. It is clear and shaped like a dome. The cornea helps to shield the rest of the eye from germs, dust, and other harmful matter. It also helps your eye to focus. If you wear contact lenses, they float on top of your corneas.
Problems with the cornea include
- Refractive errors
- Allergies
- Infections
- Injuries
- Dystrophies - conditions in which parts of the cornea lose clarity due to a buildup of cloudy material
Treatments of corneal disorders include medicines, corneal transplantation, and corneal laser surgery.

Pink Eye
Conjunctivitis is the medical name for pink eye. It involves inflammation of the outer layer of the eye and inside of the eyelid. It can cause swelling, itching, burning, discharge, and redness. Causes include
- Bacterial or viral infection
- Allergies
- Substances that cause irritation
- Contact lens products, eye drops, or eye ointments
Pink eye usually does not affect vision. Infectious pink eye can easily spread from one person to another. The infection will clear in most cases without medical care, but bacterial pink eye needs treatment with antibiotic eye drops or ointment.
