Telogen effluvium

This code describes a form of non-scarring hair loss characterized by excessive shedding of resting (telogen) hairs. It typically presents as diffuse thinning of the scalp hair, often occurring several months after a significant physiological or psychological stressor.

Use this code when documentation clearly indicates a diagnosis of telogen effluvium, often following events such as childbirth, severe illness, surgery, significant weight loss, or medication changes. Supporting documentation should include a history of diffuse hair shedding and a clinical assessment ruling out other causes of alopecia.

• Differentiate from other forms of alopecia; ensure the documentation specifies "telogen effluvium."
• Consider coding any underlying cause or precipitating factor if known and documented (e.g., postpartum state, specific medication adverse effect).
• Avoid using this code for general hair loss or unspecified alopecia; specificity is key.
