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.

Eye code 92012. Most non-Medicare payers have higher allowables for E&M codes. In this example, our commercial payer allowable is higher for the E&M code than the Eye code, so you would bill 99213.

CONCLUSION All patients using chloroquine and its derivatives must be followed-up and documented since the beginning of the therapy until they reach a cumulative dose above 100 grams. The higher the cumulative dose, the more we must be concerned with patient follow-up. 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).

A 26-year-old black female presented in office for her annual comprehensive eye exam. Her medical history was significant for Plaquenil therapy spanning 12 years with a daily dose of 200mg twice daily. She presented with a best-corrected visual acuity of 20/20 OD and 20/20 OS. All preliminary testing revealed normal findings.
