Any of the following terms in the documentation are considered as intractable – pharmacologically resistant, poorly controlled, refractory (medically) and treatment resistant. Periodic headache syndromes in child or adultĪ fifth character in migraine codes differentiates between not intractable (0) and intractable (1). Persistent migraine aura with cerebral infarction Persistent migraine aura without cerebral infarction Falling under the block ‘Diseases of the nervous system’ (G00 to G99) subset ‘episodic and paroxysmal disorders’ (G40 to G47) of ICD 10 codes, migraines come under the code G43 with 12 sub categories as under: CATEGORY Requiring better specificity and supported documentation, ICD 10 migraine coding is a challenging proposition for both coders and billers. In case of those suffering from the problem, there are medicines which can help relieve the symptoms and the pain.Ĭoding for Migraines, has become more complicated under ICD 10. Fortunately, migraine problems can be prevented by medicines. It is a fairly common problem with around twelve percent of the US population suffering from it. Migraines are recurring in nature with women more likely to suffer from them than men. The neurotransmitter changes in the brain and surrounding tissue, affected by the blood flow, may create warning signals, before the actual pain begins. This pulsating and unilateral headache results due to neurotransmitter changes and abnormal activity along the nerve pathways in the brain. These symptoms usually occur in children and teenagers. However, it is important to know that other than painful headaches, this neurological disorder can also manifest other symptoms like cyclic vomiting, abdominal pain, visual aura, vertigo, confusion, dysarthria and hemiplegia. Headaches of this type can and usually are accompanied by feelings of nausea, extra sensitivity to sound or lights and/or vomiting. Migraines can be triggered due to various reasons including hormonal changes in women, stress, skipped meals, loud noises, lack of sleep, bright lights, withdrawal from caffeine and cigarettes, amongst others. A common neurological disorder, migraine ends up giving the patient a terrible headache. However, since the diagnostic criteria for 1.3 Chronic migraine subsume a ttacks of all types, sub type s or subforms, additional coding is unnecessary for episodic subtypes of migraine. For example, a patient who has frequent attacks with aura but also some attacks without aura should be coded as 1.2 Migraine with aura and 1.1 Migraine without aura. When a patient fulfils criteria for more than one type, subtype or subform of migraine, all should be diagnosed and coded. Pr odromal and postdromal symptoms include hyperactivity, hypoactivity, depression, craving s for particular foods, repetitive yawning, fatigue and neck stiffness and /or pain. Some patients also experience a pr odromal phase, occurring hours or days before the headache, and /or a postdromal phase following headache resolution. 1.2 Migraine with aura is primarily characterized by the transient focal neurological symptoms that usually precede or sometimes accompany the headache. 1.1 Migraine without aura is a clinical syndrome characterized by headache with specific features and associated symptoms. In GBD2015, it was ranked third – highest cause of disability worldwide in both males and females under the age of 50 years. In the Global Burden of Disease S tudy 2010 (GBD2010), it was ranked as the third most prevalent disorder in the world. Many e pidemiological studies have documented its high prevalence and socio-economic and personal impacts. Migraine is a common disabling primary headache disorder. When pre-existing migraine is made significantly worse ( usually meaning a two-fold or greater increase in frequency and/or severity ) in close temporal relation to such a causative disorder, both the initial migraine diagnosis and the secondary headache diagnos i s should be given, provided that there is good evidence that the disorder can cause headache.
