S82.023 - Displaced longitudinal fracture of unspecified patella

ICD-10-CM Chapter 19: Injury, poisoning and certain other consequences of external causes · S80-S89 Injuries to the knee and lower leg (S80-S89) · Subcategory of S82.02 · FY2027

Coding Guidance

S82.023 requires a 7th character. Report the code below that matches the documentation, for example A for initial encounter for closed fracture, B for initial encounter for open fracture type I or II, C for initial encounter for open fracture type IIIA, IIIB, or IIIC.

7th Character

The appropriate 7th character is to be added to all codes from category S82

Includes, Excludes and Coding Notes

IncludesFrom S82

Conditions this code covers.

  • fracture of malleolus
Excludes 1 — Not Coded HereFrom S82

Mutually exclusive: these conditions are never reported together with this code.

  • traumatic amputation of lower leg (S88.-)
Excludes 2 — Not Included HereFrom S82

Not part of this code; report both codes when the patient has both conditions.

  • fracture of foot, except ankle (S92.-)
  • periprosthetic fracture around internal prosthetic ankle joint (M97.2)
  • periprosthetic fracture around internal prosthetic implant of knee joint (M97.1-)
NotesFrom S82

Instructional notes from the ICD-10-CM tabular list.

  • 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
Excludes 2 — Not Included HereFrom S80-S89 Injuries to the knee and lower leg (S80-S89)

Not part of this code; report both codes when the patient has both conditions.

  • 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)
Excludes 2 — Not Included HereFrom Chapter S00-T88

Not part of this code; report both codes when the patient has both conditions.

  • birth trauma (P10-P15)
  • obstetric trauma (O70-O71)
Use Additional CodeFrom Chapter S00-T88

Add a secondary code to identify the associated condition or cause when it is documented.

  • code to identify any retained foreign body, if applicable (Z18.-)
NotesFrom Chapter S00-T88

Instructional notes from the ICD-10-CM tabular list.

  • 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.
