Ophthalmology and Optometry Coding Alert

Question: What are the differences among the "review of systems" levels for the E/M codes?

Answer: Three ROS levels contribute to the level of history selected for an E/M service.
 
ROS progresses from "problem-pertinent" to "extended" and "complete." CPT has identified 14 elements of a system review: constitutional systems (e.g., fever, weight loss); eyes; ears, nose, mouth and throat; cardiovascular; respiratory; gastrointestinal; genitourinary; musculoskeletal; integumentary (i.e., skin or breast); neurological; psychiatric; endocrine; hematologic/
lymphatic; and allergic/immunologic.

In a problem-pertinent ROS, the ophthalmologist asks questions about the system directly related to the problem identified in the history of present illness (HPI).

ROS for "eyes" includes the date of the patient's last eye exam; when the patient was last checked for glaucoma (if over 50); current eye infections or injury; eyeglasses; contact lenses; current eye discharge or excessive tearing; pain; and visual disturbances or spots/floaters.

Some of these may be part of the presenting problem. However, if the ophthalmologist reviews the eyes beyond the presenting problem (e.g., "patient has worn contact lenses for the last five years"), then the additional information may be counted in the ROS.

When the ophthalmologist asks about a limited number of additional systems, he meets the criteria for an extended ROS. Important: Documentation must include positive responses and pertinent negatives for two to nine systems, according to the 1995 and 1997 Documentation Guidelines for E/M Services.

A complete ROS requires inquiring about the system(s) directly related to the problem(s), plus all other body systems. The ophthalmologist must review at least 10 organ systems and individually document those systems with positive responses and pertinent negatives. Tip: For the remaining systems, he can use a notation to indicate that all other systems are negative. Without such a notation, he must individually document at least 10 systems.
