ICD-9-CM V58.69 is a billable medical code that can be used to indicate a diagnosis on a reimbursement claim, however, V58.69 should only be used for claims with a date of service on or before September 30, 2015. For claims with a date of service on or after October 1, 2015, use an equivalent ICD-10-CM code or codes. The diagnosis coding depends on whether the patient is now taking Plaquenil. For your primary diagnosis, if the patient has completed his course of treatment of the drug, use V67.51 Follow-up examination; following completed treatment with high risk medications, not elsewhere classified. Testing services performed should have the high-risk medication diagnosis as the primary diagnosis since that is the reason for the testing..

ICD-10 is also much more specific than ICD-9. ICD-10 will now have codes for severity of diseases/problems and also for location. In ICD-10, we will code H25.11 for a nuclear sclerotic cataract in the right eye, H25.12 for a nuclear sclerotic cataract in the left eye, and H25.13 for a nuclear sclerotic cataract in both eyes. The diagnosis codes depend on whether the patient is now taking Plaquenil. If the patient has used the drug in the past but is no longer using it, code V67.51. You may need to conduct several checks after medication has discontinued to make sure latent toxicity doesn't appear.
