Note

A fracture not indicated as displaced or nondisplaced should be coded to displaced A fracture not indicated as open or closed should be coded to closed The open fracture designations are based on the Gustilo open fracture classification

Inherited from S80-S89Injuries to the knee and lower leg

Excludes 2

burns and corrosions (T20-T32) frostbite (T33-T34) injuries of ankle and foot, except fracture of ankle and malleolus (S90-S99) insect bite or sting, venomous (T63.4)

Inherited from chapter 19Injury, poisoning and certain other consequences of external causes

Excludes 2

birth trauma (P10-P15) obstetric trauma (O70-O71)

Use additional

code to identify any retained foreign body, if applicable (Z18.-)

Note

Use secondary code(s) from Chapter 20, External causes of morbidity, to indicate cause of injury. Codes within the T section that include the external cause do not require an additional external cause code The chapter uses the S-section for coding different types of injuries related to single body regions and the T-section to cover injuries to unspecified body regions as well as poisoning and certain other consequences of external causes. (T07-T88) Injury, poisoning and certain other consequences of external causes (T07-T88) (T20-T32) Burns and corrosions (T20-T32) Includes: burns (thermal) from electrical heating appliances burns (thermal) from electricity burns (thermal) from flame burns (thermal) from friction burns (thermal) from hot air and hot gases burns (thermal) from hot objects burns (thermal) from lightning burns (thermal) from radiation chemical burn [corrosion] (external) (internal) scalds Excludes2: erythema [dermatitis] ab igne (L59.0) radiation-related disorders of the skin and subcutaneous tissue (L55-L59) sunburn (L55.-)
