Adverse effect of drugs affecting uric acid metabolism, subs

This code signifies a patient experiencing an unintended and undesirable reaction to a medication that specifically impacts their uric acid levels or metabolism. This adverse effect is not due to poisoning or overdose, but rather a side effect occurring during appropriate drug use.

This code is appropriate for documenting follow-up care for a patient who previously experienced an adverse effect from a drug affecting uric acid, such as a diuretic causing hyperuricemia or allopurinol causing a rash. It should be used for subsequent visits related to monitoring, managing, or resolving this specific adverse drug reaction.

• Always sequence this code after the primary diagnosis indicating the nature of the adverse effect (e.g., hyperuricemia).
• Requires an additional code from T36-T50 to identify the specific drug causing the adverse effect.
• The 7th character "D" indicates a subsequent encounter, meaning the patient is receiving routine care during the healing or recovery phase.
