In simple words: This code covers situations related to glucocorticoid medications, including taking too much, taking too little, or experiencing negative side effects.

This code encompasses poisoning by, adverse effects of, and underdosing of glucocorticoids and their synthetic analogues. It includes adverse effects from correctly administered substances, poisoning due to overdoses, and poisoning from incorrect administration. For adverse effects, the code should be used in conjunction with a code specifying the nature of the adverse effect.

Example 1: A patient is admitted to the hospital with an overdose of prednisone, a synthetic glucocorticoid. Code T38.0X1A would be used for the initial encounter., A patient experiences Cushing's syndrome as an adverse effect of long-term prednisone use. Code T38.0X5A is used, along with a code for Cushing's syndrome., A patient on long-term glucocorticoid therapy accidentally takes less medication than prescribed and experiences symptoms of adrenal insufficiency. T38.0X6 is applied, along with a code for adrenal insufficiency.

Documentation should clearly specify the type of glucocorticoid or synthetic analogue involved, the route of administration (if applicable), the circumstances surrounding the poisoning or underdosing, and the resulting signs and symptoms. For adverse effects, the specific nature of the adverse effect must be documented. If the poisoning or adverse effect is accidental, it should be clearly documented as such.
