M1027 is reported., A patient with a history of tension headaches experiences a severe headache. An MRI is performed to assess for underlying conditions despite a likely primary headache diagnosis. M1027 is reported., A patient experiences a cluster headache. A head CT is performed as part of the initial evaluation, even though the symptoms point towards a primary headache disorder.
