    ICD-10-CM Code For Other Diseases Of Jaws: Group Overview

    The International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) code group M27 includes disorders of the jaws such as inflammatory conditions, ankylosis, and other nonneoplastic jaw diseases that affect form and function. These ICD-10-CM diagnosis codes are used to document clinical scenarios including infection, structural abnormality, or impaired jaw mobility, capturing disease severity and anatomic involvement. Accurate coding within the ICD-10-CM M27 group supports proper claim adjudication and complete clinical documentation for appropriate reimbursement.

    ICD-10-CM M27: Other Diseases Of Jaws Overview

    The ICD-10-CM M27 group covers disorders affecting the jaws, including inflammatory, developmental, and other nonneoplastic conditions that impair jaw function and structure. These diagnoses target the oral and maxillofacial region and can impact mastication, speech, and dental health. Accurate coding matters for appropriate reimbursement and for reflecting the clinical complexity of dental and maxillofacial care.

    When to Use

    Use codes from this group when a clinician documents a diagnosis involving the jaw that is not neoplastic, such as infection, ankylosis, or other structural jaw disorders. Assign the most specific code reflecting the anatomic site and clinical findings to accurately represent the patient's condition.

    Typical Clinical Scenarios

    • A young adult presents to the dental clinic after a baseball injury with acute pain, malocclusion, and visible deformity of the jaw; imaging reveals a displaced mandibular fracture involving the condylar process with impaired jaw function. A diagnosis from this group is assigned to describe the traumatic disruption and resultant jaw dysfunction requiring reduction and possible surgical fixation. Typical codes: M27.2, M27.3
    • An adolescent with long-standing difficulty with chewing and speech is evaluated in orthodontics for jaw growth abnormalities; examination and cephalometric radiographs demonstrate a congenital dentofacial anomaly with maxillomandibular malalignment contributing to malocclusion. A code from this group is used to capture the chronic developmental jaw disorder as part of pre-surgical planning and orthodontic management. Typical codes: M27.0, M27.1
    • An adult with a prior history of temporomandibular joint surgery develops persistent jaw pain, limited opening, and radiographic evidence of ankylosis or fibrous adhesion affecting mastication; this represents a post-procedural complication or other secondary jaw disorder requiring evaluation. A diagnosis from this group is assigned to document the complication and guide further treatment or rehabilitation. Typical codes: M27.61, M27.62, M27.69
