ICD-10: T38.99

ICD-10 code T38.99 pertains to "Poisoning by, adverse effect of and underdosing of other hormone antagonists." This code is part of the broader classification system used for coding various health conditions, specifically focusing on instances where patients experience negative effects from hormone antagonists, which are substances that block the action of hormones in the body.

Clinical Description

Definition

Hormone antagonists are medications that inhibit the effects of hormones. They are commonly used in the treatment of various conditions, including hormone-sensitive cancers, such as breast and prostate cancer, as well as in managing conditions like hyperthyroidism. The T38.99 code specifically addresses situations where patients may experience poisoning, adverse effects, or underdosing related to these medications.

Clinical Scenarios

1. Poisoning: This can occur when a patient ingests a harmful amount of a hormone antagonist, either accidentally or intentionally. Symptoms may vary widely depending on the specific antagonist involved and the amount ingested.

2. Adverse Effects: Patients may experience side effects from hormone antagonists, which can include nausea, fatigue, or more severe reactions such as liver dysfunction or cardiovascular issues. These effects can arise from normal therapeutic doses, indicating a need for careful monitoring.

3. Underdosing: This situation arises when a patient does not receive an adequate dose of a hormone antagonist, potentially due to medication errors, patient non-compliance, or issues with drug availability. Underdosing can lead to inadequate treatment of the underlying condition, resulting in disease progression.

Examples of Hormone Antagonists

• Tamoxifen: Used primarily in breast cancer treatment, it can lead to adverse effects such as thromboembolic events.
• Anastrozole: An aromatase inhibitor used in postmenopausal women with hormone receptor-positive breast cancer, which may cause joint pain and osteoporosis.
• Spironolactone: A diuretic that acts as an aldosterone antagonist, which can lead to hyperkalemia if overdosed.

Coding Guidelines

When coding for T38.99, it is essential to consider the following:
- Specificity: The code should be used when the specific cause of poisoning or adverse effect is not classified elsewhere. If a more specific code exists for the particular hormone antagonist involved, that code should be used instead.
