2025 ICD-10-CM code M27.0
(Active) Effective Date: N/A Revision Date: N/A Musculoskeletal System - Dentofacial anomalies [including malocclusion] and other disorders of jaw Diseases of the musculoskeletal system and connective tissue (M00-M99) Feed
Developmental disorders of the jaws, including malformations of the upper and lower jaw bones.
Modifiers may be applied depending on the circumstances of the encounter and the procedures performed, in accordance with standard coding practices.
The medical necessity for treatment varies depending on the severity and symptoms of the jaw disorder.Treatment might be necessary to address functional impairments (such as difficulty breathing or eating) or significant cosmetic concerns.
Oral and Maxillofacial Surgeons, Dentists, Orthodontists may be involved in diagnosis and treatment depending on the severity and specific presentation of the jaw anomaly.
In simple words: This code describes birth defects affecting the shape and growth of the upper or lower jaw bones.These may show up as dents or bumps on the jaw, and sometimes cause sores that hurt. Doctors use exams and X-rays to diagnose this.
M27.0, Developmental disorders of jaws, encompasses congenital malformations and dysplasias affecting the development of the maxilla (upper jaw) and/or mandible (lower jaw).These can manifest as depressions, protrusions, or other irregularities in the bone structure.The condition may or may not be symptomatic; however, if ulceration develops due to trauma near the affected area, it can cause pain and discomfort. Diagnosis relies on oral examination and imaging studies (X-rays, CT scans).
Example 1: A newborn infant presents with a visibly small mandible (micrognathia), requiring assessment for potential breathing difficulties and feeding challenges.M27.0 would be used to code the developmental jaw anomaly. Further codes might be necessary to describe associated conditions., A child is diagnosed with a bony protrusion (exostosis) on their mandible, causing no symptoms but noted during a routine dental examination.The code M27.0 accurately represents the developmental jaw disorder., An adult experiences an ulcerated area near a pre-existing bony depression on their maxilla, resulting in pain and discomfort. The code M27.0 would be utilized to represent the jaw anomaly, and additional codes would document the ulceration and its associated symptoms.
Detailed clinical history, including family history of jaw anomalies. Comprehensive oral examination notes.Radiographic images (X-rays, CT scans) demonstrating the jaw malformation.Documentation of any associated symptoms or complications, such as ulceration, pain, or feeding difficulties.
** Further investigation may be necessary to identify underlying genetic or syndromic causes.The severity of the anomaly and presence or absence of associated symptoms will influence the clinical management and treatment decisions.Appropriate documentation is essential for accurate coding and reimbursement.
