S02 is a non-billable ICD-10-CM category code for fracture of skull and facial bones, so it cannot be submitted on claims. Use a more specific code from this category instead, such as S02.0XXA, S02.0XXB, S02.0XXD, and S02.0XXG.

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 S02: its own notes plus those printed at block S00-S09 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.

From Block S00-S09 Injuries to the head applies to 1,934 codes
  • injuries of ear
  • injuries of eye
  • injuries of face [any part]
  • injuries of gum
  • injuries of jaw
  • injuries of oral cavity
  • injuries of palate
  • injuries of periocular area
  • injuries of scalp
  • injuries of temporomandibular joint area
  • injuries of tongue
  • injuries of tooth

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.

From Block S00-S09 Injuries to the head applies to 1,934 codes
  • burns and corrosions (T20-T32)
  • effects of foreign body in ear (T16)
  • effects of foreign body in larynx (T17.3)
  • effects of foreign body in mouth NOS (T18.0)
  • effects of foreign body in nose (T17.0-T17.1)
  • effects of foreign body in pharynx (T17.2)
  • effects of foreign body on external eye (T15.-)
  • frostbite (T33-T34)
  • 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.-)

Code Also

A second code may be needed to fully describe the condition; the note gives no sequencing direction.

On S02 itself
  • any associated intracranial injury (S06.-)
From Block S00-S09 Injuries to the head applies to 1,934 codes
  • for any associated infection

Notes

General instructions on how these codes are used.

On S02 itself
  • A fracture not indicated as open or closed should be coded to closed
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 each code from category S02
Values for category S02 Skull, Spine and Pelvis Fracture Encounter
  • Ainitial encounter for closed fracture
  • Binitial encounter for open fracture
  • Dsubsequent encounter for fracture with routine healing
  • Gsubsequent encounter for fracture with delayed healing
  • Ksubsequent encounter for fracture with nonunion
  • Ssequela

Referenced in Other NotesGuidance

Instructional notes printed at other codes that name S02, its category, or a range that includes it.

Excludes1 1

These codes carry an Excludes1 note naming S02: they are not reported together with it, unless the two conditions are unrelated.

  • S01 Open wound of head
    open skull fracture (S02.- with 7th character B)

Code First 1

These codes say to code first a condition named in the note, and S02 is one of the conditions named.

Use Additional Code 1

These codes say to use an additional code from the note, and S02 is one of the codes named.

  • S07 Crushing injury of head
    skull fractures (S02.-)

Code Also 2

These codes say S02 may also be needed to fully describe the condition. The note gives no sequencing direction.

  • S04 Injury of cranial nerve
    skull fracture (S02.-)
  • S06 Intracranial injury
    skull fracture (S02.-)

Patient EducationClinical

Facial Injuries and Disorders

Face injuries and disorders can cause pain and affect how you look. In severe cases, they can affect sight, speech, breathing and your ability to swallow. Fractures (broken bones), especially in the bones of your nose, cheekbone and jaw, are common facial injuries.

Questions About S02Overview

What is the ICD-10 code for fracture of skull and facial bones?

S02 is the ICD-10-CM category for fracture of skull and facial bones, but it is a non-billable header: claims need a more specific code from this category, listed on this page.

Is S02 (Fracture of skull and facial bones) a billable code?

No. This is a category header that groups the codes for fracture of skull and facial bones, and headers cannot be submitted on claims. Claims for fracture of skull and facial bones need a more specific code from this category, such as S02.0XXA, S02.0XXB, and S02.0XXD.
