Eye exam codes follow a different set of documentation rules than E/M codes. They require specific exam elements, like ophthalmoscopy and external eye exam, plus a note on whether the visit is for a new or existing diagnostic treatment plan.
E/M codes, by contrast, follow the standard history, exam, and medical decision-making rules used across all specialties. The right choice depends on which set of requirements the visit actually meets, and some payers reimburse one type higher than the other.
Picking the wrong code family for the documentation on file is one of the most common ophthalmology billing errors.
