Adverse effect of glucocort/synth analog, init

This code identifies an unintended and harmful reaction to glucocorticoid medications or their synthetic counterparts when the patient is first presenting for treatment of this adverse effect. These reactions are not due to overdose or poisoning, but rather the body's negative response to a correctly administered therapeutic dose.

Apply this code when a patient experiences an adverse reaction to corticosteroids (e.g., prednisone, dexamethasone) or similar synthetic drugs, and this is the initial encounter for managing that specific adverse effect. Examples include new onset steroid-induced hyperglycemia, Cushingoid features, or psychiatric disturbances directly attributable to glucocorticoid therapy.

• Always sequence this code first, followed by codes for the specific manifestation of the adverse effect.
• Ensure documentation clearly states the reaction is an adverse effect, not poisoning or underdosing.
• Verify the encounter is indeed the "initial encounter" for the adverse effect, not a subsequent visit.
