2019 ICD-10-CM Diagnosis Code M27.2

Inflammatory conditions of jaws

    2016 2017 2018 2019 Billable/Specific Code
  • M27.2 is a billable/specific ICD-10-CM code that can be used to indicate a diagnosis for reimbursement purposes.
  • The 2019 edition of ICD-10-CM M27.2 became effective on October 1, 2018.
  • This is the American ICD-10-CM version of M27.2 - other international versions of ICD-10 M27.2 may differ.
Applicable To
  • Osteitis of jaw(s)
  • Osteomyelitis (neonatal) jaw(s)
  • Osteoradionecrosis jaw(s)
  • Periostitis jaw(s)
  • Sequestrum of jaw bone

Certain conditions have both an underlying etiology and multiple body system manifestations due to the underlying etiology. For such conditions the ICD-10-CM has a coding convention that requires the underlying condition be sequenced first followed by the manifestation. Wherever such a combination exists there is a "use additional code" note at the etiology code, and a "code first" note at the manifestation code. These instructional notes indicate the proper sequencing order of the codes, etiology followed by manifestation. In most cases the manifestation codes will have in the code title, "in diseases classified elsewhere." Codes with this title are a component of the etiology/manifestation convention. The code title indicates that it is a manifestation code. "In diseases classified elsewhere" codes are never permitted to be used as first listed or principle diagnosis codes. They must be used in conjunction with an underlying condition code and they must be listed following the underlying condition.

Type 2 Excludes Help
A type 2 excludes note represents "not included here". A type 2 excludes note indicates that the condition excluded is not part of the condition it is excluded from but a patient may have both conditions at the same time. When a type 2 excludes note appears under a code it is acceptable to use both the code (M27.2) and the excluded code together.
