Pattern of Retinopathy: Although the locus of toxic damage is parafoveal in many eyes, Asian patients often show an extramacular pattern of damage. Dose: We recommend a maximum daily HCQ use of 5.0 mg/kg real weight, which correlates better with risk than ideal weight.

Abstract. Background The American Academy of Ophthalmology recommendations on screening for chloroquine CQ and hydroxychloroquine HCQ retinopathy are revised in light of new information about the prevalence of toxicity, risk factors, fundus distribution, and effectiveness of screening tools. The study findings revealed that when hydroxychloroquine was used at doses 5mg /kg, the risk of retinopathy was 1% in the first 5 yrs. 2% in 10 yrs. 20 % after 20 yrs. There was a dose response, such that those receiving doses greater that 5 mg / kg had the greatest risk of retinal toxicity. Risk of Toxicity: The risk of toxicity is dependent on daily dose and duration of use. There are no similar demographic data for CQ, but dose comparisons in older literature suggest using 2.3 mg/kg real weight.

Initial evaluation for macular degeneration related to central vision loss or has experienced such loss resulting in vision measured at or below 20/70. Limitations Question What is the best way to code for Plaquenil toxicity observation first, if the patient was referred by the family doctor for a baseline exam prior to the start of treatment; second, if the patient returns six months after the start of treatment to assess ocular changes; and, third, if the patient returns six months later and shows adverse ocular changes? Answer When billing Plaquenil examinations, or any other high risk medication exams, it is appropriate to bill the systemic disease or any ocular manifestations as the primary diagnosis since many payers may not reimburse for the high-risk medication diagnosis as a stand-alone diagnosis. Testing services performed should have the high-risk.
