2026 ICD-10-CM Diagnosis Code S02.80XGFracture of other specified skull and facial bones, unspecified side, subsequent encounter for fracture with delayed healing
S02.80XG is a billable ICD-10-CM diagnosis code for fracture of other specified skull and facial bones, unspecified side, subsequent encounter for fracture with delayed healing. The 7th character G reports a subsequent encounter for a fracture that is healing more slowly than expected. It is valid on HIPAA claims for fiscal year 2026 (October 1, 2025 through September 30, 2026) and groups to MS-DRG 559 through 561. The code is exempt from POA reporting. In AHRQ's Clinical Classifications Software (CCSR), this diagnosis falls under Fracture of head and neck, subsequent encounter.

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).

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 S02.80XGOverview
Is S02.80XG a billable code?
Yes. This is a billable ICD-10-CM code, specific enough to report fracture of other specified skull and facial bones, unspecified side, subsequent encounter for fracture with delayed healing on HIPAA-covered claims from October 1, 2025 through September 30, 2026.
What does the 7th character G in S02.80XG mean?
The final character G reports a subsequent encounter where the fracture of other specified skull and facial bones, unspecified side is healing more slowly than expected.
What MS-DRG does S02.80XG group to?
When fracture of other specified skull and facial bones, unspecified side, subsequent encounter for fracture with delayed healing is the principal diagnosis on an inpatient stay, it groups to MS-DRG 559, 560, 561, with relative weights from 0.8039 to 1.8649 depending on complications. Higher weights mean higher Medicare reimbursement.
Is S02.80XG exempt from POA reporting?
Yes. CMS lists this code among those exempt from present on admission reporting, so hospitals do not assign a POA indicator for fracture of other specified skull and facial bones, unspecified side, subsequent encounter for fracture with delayed healing on inpatient claims.
What is the ICD-9 equivalent of S02.80XG?
Under the General Equivalence Mappings, fracture of other specified skull and facial bones, unspecified side, subsequent encounter for fracture with delayed healing converts to ICD-9-CM V54.19 (aftrce traum fx bone NEC). The mapping is approximate, so confirm the match fits the documentation.
Footnotes
[1] Not chronic - A diagnosis code that does not fit the criteria for chronic condition (duration, ongoing medical treatment, and limitations) is considered not chronic. Some codes designated as not chronic are acute conditions. Other diagnosis codes that indicate a possible chronic condition, but for which the duration of the illness is not specified in the code description (i.e., we do not know the condition has lasted 12 months or longer) also are considered not chronic.
