What This Code Means

Temporary hair loss that occurs when hair follicles prematurely shift from the growth phase to the resting phase, often triggered by stress, illness, or medication.

Coding Tips

• •Document the triggering event (stress, surgery, illness, medication) in the medical record when possible to support clinical decision-making
• •This condition is typically reversible; note the timeline of hair loss onset to help distinguish from other alopecia types
