2026 ICD-10-CM Diagnosis Code S02Fracture of skull and facial bones
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).

Tabular List NotesGuidance

Code Also
- any associated intracranial injury S06
7th Character Note
- The appropriate 7th character is to be added to each code from category S02
7th Character
- A - initial encounter for closed fracture
- B - initial encounter for open fracture
- D - subsequent encounter for fracture with routine healing
- G - subsequent encounter for fracture with delayed healing
- K - subsequent encounter for fracture with nonunion
- S - sequela
- A fracture not indicated as open or closed should be coded to closed
A "code also" note instructs that two codes may be required to fully describe a condition, but this note does not provide sequencing direction.
Certain ICD-10-CM categories have applicable 7th characters. The applicable 7th character is required for all codes within the category, or as the notes in the Tabular List instruct. The 7th character must always be the 7th character in the data field. If a code that requires a 7th character is not 6 characters, a placeholder X must be used to fill in the empty characters.
Indicates that a seventh character is to be assigned to codes in a subcategory.
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
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.
