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).

  • 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.

Clinical InformationClinical

  • Tooth Fracture

    broken tooth affecting any portion of tooth: root fracture, crown-root, broken tooth (crown fracture), chipped tooth. a crown fracture can involve the pulp. tooth fracture sequelae range in severity from cosmetic defects to tooth death. involvement of the pulp is a more important indicator of severity of tooth fracture than is the amount of the tooth affected.

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 S02.5XXAOverview

What is the ICD-10 code for fracture of tooth (traumatic), initial encounter for closed fracture?

The ICD-10-CM code for fracture of tooth (traumatic), initial encounter for closed fracture is S02.5XXA (sometimes written as S025XXA). It is billable on HIPAA-covered claims from October 1, 2026 through September 30, 2027.

Is S02.5XXA (Fracture of tooth (traumatic)) a billable code?

Yes. This is a billable ICD-10-CM code, specific enough to report fracture of tooth (traumatic), initial encounter for closed fracture on HIPAA-covered claims from October 1, 2026 through September 30, 2027.

What does the 7th character A in S02.5XXA mean?

The final character A marks the initial encounter: use it while the patient is receiving active treatment for fracture of tooth (traumatic), such as an emergency visit or first evaluation. In this category the CMS Tabular List defines A as "initial encounter for closed fracture".

What MS-DRG does S02.5XXA group to?

When fracture of tooth (traumatic), initial encounter for closed fracture is the principal diagnosis on an inpatient stay, it groups to MS-DRG 964, 965, 159, 158, 157, 963, with relative weights from 0.6890 to 2.6361 depending on complications. Higher weights mean higher Medicare reimbursement.

Can S02.5XXA be reported with K03.81?

Not as a rule. The Excludes1 note at S02.5, which applies to S02.5XXA, lists "cracked tooth (nontraumatic) (K03.81)". 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).
