2025 ICD-10-CM code T44.7

Poisoning by, adverse effect of, or underdosing of beta-adrenoreceptor antagonists.

Consult the official ICD-10-CM coding guidelines for complete instructions on using this code. Pay special attention to the rules for poisoning, adverse effects, and underdosing and the requirement for additional codes to describe the manifestations of poisoning.

Modifiers may be applicable depending on the circumstances of the encounter (e.g., place of service, type of service). Refer to the CPT and HCPCS modifier guidelines for appropriate usage.

Medical necessity for coding T44.7 is established when a patient presents with symptoms directly attributable to beta-blocker ingestion, either accidental or intentional, and requires medical intervention.Documentation must support a clear causal link between the medication and the adverse event.

The clinical responsibility for coding T44.7 falls on the physician or qualified healthcare provider documenting the patient's encounter.They must accurately assess the patient's symptoms and determine if the symptoms are related to beta-blocker use.

IMPORTANT Additional codes may be necessary to specify the adverse effect experienced (e.g., bradycardia, hypotension, bronchospasm).If the poisoning is due to intentional self-harm, consider additional codes from Chapter 20 (External causes of morbidity).

In simple words: This code is used when someone experiences a problem due to taking too much, too little, or having a bad reaction to a beta-blocker medication, such as a medicine for high blood pressure or heart problems.

This ICD-10-CM code classifies poisoning, adverse effects, or underdosing resulting from beta-adrenoreceptor antagonist medications.Beta-blockers are used to treat various conditions, including hypertension, angina, and arrhythmias.This code encompasses accidental or intentional ingestion, overdose, or underdosing leading to adverse reactions.Specific adverse effects should be coded separately. The seventh character (A, D, or S) indicates the encounter (initial, subsequent, or sequela).

Example 1: A 65-year-old male patient presents to the emergency department with bradycardia, hypotension, and dizziness after accidentally ingesting a double dose of his metoprolol (a beta-blocker) medication., A 40-year-old female patient reports experiencing shortness of breath and wheezing after starting a new prescription for propranolol (a beta-blocker). This is an adverse reaction requiring further investigation and treatment., A 70-year-old female patient was found unresponsive.Toxicology screening revealed elevated levels of atenolol (a beta-blocker), indicating an overdose due to intentional self-harm.

Detailed documentation should include: patient demographics, medication history (including name, dosage, frequency, and route of administration of the beta-blocker),presentation of symptoms, physical examination findings, laboratory test results (e.g., serum drug levels), diagnostic procedures performed, treatment provided, and the physician's assessment linking the symptoms to the beta-blocker use.

** The seventh character (A, D, or S) should be appended based on the encounter context.Always cross-reference with other relevant codes, such as codes for specific adverse effects and codes for external causes, to ensure complete and accurate coding.
