Question  Correct  Explanation

6   1       )  1 Diabetic macular edema: Swelling of the retina in diabetes mellitus due to leaking of fluid

                        from blood vessels within the macula. The macula is the central portion of the retina, a small

                         area rich in cones, the specialized nerve endings that detect color and upon which

                        daytime vision depends.

    6      2  )   1 Diabetic retinopathy is defined as retinal changes occurring in long-term diabetes and

                        characterized by punctate hemorrhages, microaneurysms, and sharply defined waxy

                        exudates.

    6      3  )   3 ICD-9 code 327.53*, Sleep related bruxism, involves the grinding or clenching of teeth

                        during sleep. 

                       

    6      4  )   2 REM is the acronym for Rapid Eye Movement, the periodic jerky movement of the eyes

                        band called REM - Jeff).

    6      5  )   4 What three codes are used to report polysomnography?

                        CPT codes 95808, 95810 or 95811 to report these tests.

    6      9  )   4 Delayed sleep-phase syndrome (DSPS) 327.31, is a chronic sleep disorder in which the

                        patient's internal body clock is not in sync with the morning-rise / evening-sleep pattern of

                        the majority of adults. A growing body of evidence suggests that the problem is genetic.

                        DSPS patients may have a severely reduced reaction to the re-setting effect of light on the

                        body clock.
