The sequence of information to provide a complete status of the medical condition requires each additional character to build on the previous character placed before it. While the ICD 10 code for migraine, G43 indicates treatment for migraine in order to receive payment for the same, the coder has to add three additional characters to the basic code. Although migraines with aura are rarely accompanied by seizures in case of migraine seizure the reporting codes would be – G43.1 (Migraines with aura) and depending on the type of seizure, codes from either G40 (epilepsy) or R56.9 (unspecified convulsions). Thus a migraine without aura, caused due to an effect of nitroglycerine will be reported with two codes – G43.0 (migraine without aura) and T46.3x5A (adverse effect of coronary vasodilators). The following examples should help understand this better.ĭrugs like oral contraceptives and nitroglycerine can trigger migraines. Migraines may be associated with or cause additional conditions and these need to be reported with additional codes. Menstrual migraine, intractable, without status migrainosus Menstrual migraine, intractable, with status migrainosus Menstrual migraine, not intractable, without status migrainosus Menstrual migraine, not intractable, with status migrainosus Other migraine, intractable, without status migrainosus Other migraine, intractable, with status migrainosus Other migraine, not intractable, without status migrainosus Other migraine, not intractable, with status migrainosus This sixth character identifies migraine which has lasted more than 72 hours (1) or migraine which has lasted less than 72 hours (9).Ĭode G43.8 which specifies other migraine covers the following: CATEGORY Other than migraine variants under G43.A to G43.D, other migraine ICD 10 codes can also have a sixth character. 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.
