S52.025N
Nondisplaced fracture of olecranon process without intraarticular extension of left ulna, subsequent encounter for open fracture type IIIA, IIIB, or IIIC with nonunion
This code does not map to a risk-adjusting HCC in the loaded models.
Coding notes
Excludes 1 never coded together · Excludes 2 may co-exist
traumatic amputation of forearm (S58.-)
fracture at wrist and hand level (S62.-) periprosthetic fracture around internal prosthetic elbow joint (M97.4)
The appropriate 7th character is to be added to all codes from category S52

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