About coding Frozen
The ICD-10-CM code for Frozen is T69.9 (Effect of reduced temperature, unspecified). The official index lists 2 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on T69.9.
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).
