Drug-induced headache, not elsewhere classified
ICD-10 G44.4 is a billable code used to indicate a diagnosis of drug-induced headache, not elsewhere classified.
Drug-induced headaches are a type of headache disorder that occurs as a result of medication use. These headaches can arise from both overuse of medications intended to treat headaches, such as analgesics, and from the side effects of other medications. The pathophysiology involves alterations in neurotransmitter levels, particularly serotonin, which can lead to headache symptoms. Patients may experience a range of headache types, including tension-type headaches and migraines, depending on the medication involved. Common triggers include the abrupt withdrawal of medications, excessive use of pain relievers, and the introduction of new medications that may have headache as a side effect. Preventive treatments may include tapering off offending medications, switching to alternative therapies, and implementing lifestyle modifications. Accurate diagnosis and coding are essential to ensure appropriate treatment and management of these headaches, as they can significantly impact a patient's quality of life.
