About coding freezing

The ICD-10-CM code for freezing is T69.9 (Effect of reduced temperature, unspecified).

Within T69, choose T69.9 (Effect of reduced temperature, unspecified) only when documentation doesn't support a more specific option: Immersion hand and foot (T69.0), Chilblains (T69.1) and other specified effects of reduced temperature (T69.8).

Codes in this range require a 7th character: A for initial encounter, D for subsequent encounter and S for sequela. Use placeholder "X" characters to fill any empty positions before the 7th character.

Use an additional code to identify source of exposure: Exposure to excessive cold of man-made origin (W93) and Exposure to excessive cold of natural origin (X31).
