2025 ICD-10-CM code T50.0
Poisoning by, adverse effect of, and underdosing of mineralocorticoids and their antagonists.
Yes, modifiers can be applied to further specify the encounter (e.g., initial encounter, subsequent encounter, sequela).
Medical necessity is established by the underlying condition for which the mineralocorticoid or antagonist was prescribed.In cases of poisoning or adverse effects, the medical necessity relates to the treatment required to manage the resulting symptoms or complications.
Clinicians are responsible for correctly identifying, documenting, and coding the specific scenario related to mineralocorticoid use.This includes determining whether the case is an adverse effect, poisoning due to overdose or incorrect substance, or underdosing.Proper documentation should specify the substance involved, the route of administration (if applicable), and the clinical manifestations.If the scenario is an adverse effect, the specific nature of the effect should be documented and coded appropriately with an additional code.
- Injury, poisoning and certain other consequences of external causes (S00-T88)
- T50-T50.9: Poisoning by diuretics and other and unspecified drugs, medicaments and biological substances
In simple words: This code represents a condition related to mineralocorticoids, such as aldosterone, which regulate salt and water balance in the body.It covers situations like an overdose, taking the wrong medication, or not taking enough of the prescribed medication, and also includes any harmful side effects that may occur, even when taken correctly.
This code encompasses poisoning by, adverse effects of, and underdosing of mineralocorticoids and their antagonists.It includes adverse effects from correctly administered substances, poisoning due to overdose, poisoning from incorrect substances given or taken, and underdosing from unintentionally or intentionally taking less than the prescribed amount.
Example 1: A patient accidentally takes two doses of their prescribed fludrocortisone, resulting in symptoms of mineralocorticoid excess, such as high blood pressure and water retention., A patient experiences severe hyperkalemia (high potassium) due to inadequate spironolactone dosage. This is considered underdosing and should be coded as T50.0., A patient is prescribed eplerenone and subsequently develops gynecomastia (breast enlargement in males) as an adverse effect.While the adverse effect itself would be coded separately, the underlying cause related to the medication is captured with T50.0.
Documentation should clearly indicate the specific mineralocorticoid or antagonist involved, the circumstances of the event (accidental poisoning, intentional overdose, underdosing, adverse effect), the route of administration (if applicable), and the presenting signs and symptoms.In cases of adverse effects, the specific manifestation should be thoroughly documented.
** Excludes1: birth trauma (P10-P15), obstetric trauma (O70-O71).Excludes2: abuse and dependence of psychoactive substances (F10-F19), abuse of non-dependence-producing substances (F55.-), immunodeficiency due to drugs (D84.821), drug reaction and poisoning affecting newborn (P00-P96), pathological drug intoxication (inebriation) (F10-F19)
