M26.221
ICD-10-CMThis code signifies a malocclusion where the posterior teeth do not meet when the jaws are closed, leaving a gap between the upper and lower molars and premolars. This open bite specifically occurs in the back of the mouth, affecting the chewing surfaces. It indicates a vertical discrepancy in the posterior dental arch.
Use this code when documentation clearly states an "open posterior bite" or "posterior open occlusal relationship." This condition is often identified during orthodontic evaluations or general dental examinations. Supporting documentation should include clinical notes detailing the lack of posterior tooth contact upon occlusion.
