Questions About K08.89Overview
Is K08.89 (Other specified disorders of teeth and supporting structures) a billable code?
Yes. This is a billable ICD-10-CM code, specific enough to report other specified disorders of teeth and supporting structures on HIPAA-covered claims from October 1, 2025 through September 30, 2026.
What MS-DRG does K08.89 group to?
When other specified disorders of teeth and supporting structures is the principal diagnosis on an inpatient stay, it groups to MS-DRG 157, 158, 159, with relative weights from 0.7085 to 1.7168 depending on complications. Higher weights mean higher Medicare reimbursement.
What is the ICD-9 equivalent of K08.89?
Under the General Equivalence Mappings, other specified disorders of teeth and supporting structures converts to ICD-9-CM 525.8 (dental disorder 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.
