S82 is a non-billable ICD-10-CM category code for fracture of lower leg, including ankle, so it cannot be submitted on claims. Use a more specific code from this category instead, such as S82.001A, S82.001B, S82.001C, and S82.001D.

Coding GuidelinesGuidance

The principles of multiple coding of injuries should be followed in coding fractures. Fractures of specified sites are coded individually by site, to the level of detail furnished by medical record content.

A fracture not indicated as open or closed should be coded to closed. A fracture not indicated whether displaced or not displaced should be coded to displaced.

Initial vs. Subsequent Encounter for Fractures

Traumatic fractures are coded using the appropriate 7th character for initial encounter (A, B, C) while the patient is receiving active treatment for the fracture. The appropriate 7th character for initial encounter should also be assigned for a patient who delayed seeking treatment for the fracture or nonunion.

Fractures are coded using the appropriate 7th character for subsequent care for encounters after the patient has completed active treatment of the fracture and is receiving routine care for the fracture during the healing or recovery phase.

Care for complications of surgical treatment for fracture repairs during the healing or recovery phase should be coded with the appropriate complication codes.

Care of complications of fractures, such as malunion and nonunion, should be reported with the appropriate 7th character for subsequent care with nonunion (K, M, N) or subsequent care with malunion (P, Q, R).

The open fracture designations in the assignment of the 7th character for fractures of the forearm, femur and lower leg, including ankle are based on the Gustilo open fracture classification. When the Gustilo classification type is not specified for an open fracture, the 7th character for open fracture type I or II should be assigned (B, E, H, M, Q).

Instructional NotesGuidance

Instructions from the official ICD-10-CM Tabular List that apply to S82: its own notes plus those printed at block S80-S89 and Chapter 19. A note printed at a category, block or chapter applies to every code under it.

Includes

Further defines, or gives examples of, the content of the category.

  • fracture of malleolus

Excludes1

Not coded here: the excluded code is never reported together with this one, unless the two conditions are unrelated.

  • traumatic amputation of lower leg (S88.-)

Excludes2

Not included here: the excluded condition is not part of this code, but a patient may have both, so both codes may be reported.

On S82 itself
  • 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-)
From Block S80-S89 Injuries to the knee and lower leg applies to 4,680 codes
  • 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)
From Chapter 19 (S00-T88) Injury, poisoning and certain other consequences of external causes applies to 41,187 codes

Use Additional Code

Add a second code, after this one, to fully describe the condition.

From Chapter 19 (S00-T88) Injury, poisoning and certain other consequences of external causes applies to 41,187 codes
  • code to identify any retained foreign body, if applicable (Z18.-)

Notes

General instructions on how these codes are used.

On S82 itself
  • 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
From Chapter 19 (S00-T88) Injury, poisoning and certain other consequences of external causes applies to 41,187 codes
  • 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.

7th Character

Every code in the category takes a 7th character from the listed values, with the placeholder X filling any empty positions before it.

  • The appropriate 7th character is to be added to all codes from category S82
Values for category S82 Open Fracture Type Encounter
  • Ainitial encounter for closed fracture
  • Binitial encounter for open fracture type I or II
  • Cinitial encounter for open fracture type IIIA, IIIB, or IIIC
  • Dsubsequent encounter for closed fracture with routine healing
  • Esubsequent encounter for open fracture type I or II with routine healing
  • Fsubsequent encounter for open fracture type IIIA, IIIB, or IIIC with routine healing
  • Gsubsequent encounter for closed fracture with delayed healing
  • Hsubsequent encounter for open fracture type I or II with delayed healing
  • Jsubsequent encounter for open fracture type IIIA, IIIB, or IIIC with delayed healing
  • Ksubsequent encounter for closed fracture with nonunion
  • Msubsequent encounter for open fracture type I or II with nonunion
  • Nsubsequent encounter for open fracture type IIIA, IIIB, or IIIC with nonunion
  • Psubsequent encounter for closed fracture with malunion
  • Qsubsequent encounter for open fracture type I or II with malunion
  • Rsubsequent encounter for open fracture type IIIA, IIIB, or IIIC with malunion
  • Ssequela

Patient EducationClinical

Fractures

A fracture is a break in a bone. Fractures are usually caused by injuries. Since they can sometimes be serious, it's important to get medical care right away if you think you have a fracture.

Questions About S82Overview

What is the ICD-10 code for fracture of lower leg, including ankle?

S82 is the ICD-10-CM category for fracture of lower leg, including ankle, but it is a non-billable header: claims need a more specific code from this category, listed on this page.

Is S82 (Fracture of lower leg, including ankle) a billable code?

No. This is a category header that groups the codes for fracture of lower leg, including ankle, and headers cannot be submitted on claims. Claims for fracture of lower leg, including ankle need a more specific code from this category, such as S82.001A, S82.001B, and S82.001C.

Can S82 be reported with a code from S88?

Not as a rule. The Excludes1 note on S82 lists "traumatic amputation of lower leg (S88.-)". An Excludes1 note means the excluded code is never reported together with this one; the only exception is when the two conditions are unrelated to each other (Official Guidelines, Section I.A.12.a).
