Unspecified TMJ joint disorder, unspecified side

This code signifies a temporomandibular joint (TMJ) disorder where the specific type of dysfunction (e.g., arthralgia, ankylosis, derangement) is not documented, and the affected side (left, right, or bilateral) is also unknown. It represents a general diagnosis of TMJ pathology without further specification.

Use this code when the medical record indicates a TMJ disorder but lacks details regarding the specific nature of the disorder or the laterality. This is appropriate when documentation only states "TMJ disorder" or "TMD" without further elaboration on the clinical findings or affected side.

• Avoid using this code if documentation specifies the type of TMJ disorder (e.g., M26.62 for articular disc disorder) or the affected side.
• Query the provider for more specific documentation regarding the type of TMJ disorder and laterality whenever possible.
• This code should be a last resort when no further specificity can be obtained from the medical record.
