Code Description

ICD-10 N94.3 is a billable code used to indicate a diagnosis of premenstrual tension syndrome.

Key Diagnostic Point:

Premenstrual tension syndrome (PMTS) is a condition characterized by a range of physical and emotional symptoms that occur in the luteal phase of the menstrual cycle, typically resolving with the onset of menstruation. Symptoms may include mood swings, irritability, anxiety, depression, fatigue, and physical symptoms such as bloating, breast tenderness, and headaches. The severity of symptoms can vary significantly among individuals, and while some may experience mild discomfort, others may find their daily functioning severely impaired. The exact etiology of PMTS is not fully understood, but it is believed to involve hormonal fluctuations, particularly involving estrogen and progesterone, as well as neurotransmitter changes. Diagnosis is primarily clinical, based on symptom tracking and exclusion of other conditions. Treatment options may include lifestyle modifications, dietary changes, pharmacological interventions such as antidepressants or hormonal therapies, and cognitive-behavioral therapy. Accurate coding is essential for appropriate management and reimbursement, as PMTS can significantly impact a woman's quality of life and overall reproductive health.
