Her rheumatologist instructed her to undergo a baseline ocular examination prior to initiating Plaquenil (hydroxychloroquine, Sanofi-Aventis) therapy. Toxic maculopathy associated with chloroquine use was first documented in the literature five decades ago.1 In the United States, Plaquenil––an analog to chloroquine––is used to treat a variety of conditions, including rheumatoid arthritis, lupus and several distinct inflammatory disorders. Although the incidence of macular toxicity is infrequent with Plaquenil use (at a dosage of 200mg or 400mg q.d.), its visual impact can be devastating.

Short description Adverse effect of systemic anti-infect/parasit, init The 2020 edition of ICD-10-CM T37.8X5A became effective on October 1, 2019. ICD-10-CM codes are to be used and reported at their highest number of characters available. A 3-character code is to be used only if it is not further subdivided. A code is invalid if it has not been coded to the full number of characters required for that code, including the 7 th character, if applicable. Every October, new ICD-10-CM codes are announced to take full effect January 1 of the following year. The code changes for 2019 have been compiled by PECAA into a list of 2019 optometry coding guidelines —keep an eye out for the upcoming 2020 code changes. Initially, central visual acuity may be unaffected, but the patient may notice related paracentral scotomas that often interfere with reading. The associated classic retinal toxicity is described as a bull’s eye maculopathy (ring of depigmented retinal pigment epithelium that spares the foveal area).

Plaquenil-Induced Toxic Maculopathy - Decision-Maker PLUS. The Ultimate Guide to Optometry Billing and Coding.. ICD-10 Code for Completion of Plaquenil Treatment - American.. 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 medication diagnosis as the primary diagnosis since that is the reason for the testing. Marie Stamper, CMM Ward Eye Center, FL Answer Plaquenil hydroxychloroquine is a drug used to treat malaria, lupus erythematous, ormost commonlyrheumatoid arthritis. A potential side effect of the drug is ocular change that can affect the patients vision; the patient should be monitored regularly to check for these changes. 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.
