In simple words: This is an eye exam where the doctor checks how clearly your child can see using an eye chart with letters of different sizes. It's done for both eyes.

This code represents a screening test for visual acuity using graduated stimuli (e.g., Snellen chart) to obtain a quantitative measurement in both eyes. It is typically used in pediatric settings.

Example 1: A 5-year-old child has a routine well-child visit with their pediatrician. As part of the visit, the pediatrician performs a visual acuity screening using a Snellen chart to check for any potential vision problems., A 3-year-old child is referred to their pediatrician by their preschool teacher who has noticed the child squinting and having difficulty seeing objects on the board. The pediatrician uses a Snellen chart to quantitatively assess their visual acuity., A 6-year-old child is scheduled for a sports physical before participating in soccer. The physician performs a visual acuity screening using a Snellen chart, as it's required by the sports league.

The documentation should include the type of screening test used (e.g., Snellen chart), the visual acuity measurements for each eye, and any observations or findings related to the child's vision.

** While some payers may bundle this code with preventive visits, it is important to always report 99173 to accurately document the service provided. Some Medicaid payers require reporting this code even if it is not separately reimbursed.
