Q& a: Coding Headaches For Patients With Hypertension
Q: If a physician orders a consultation for a patient who is experiencing a headache due to hypertension, which ICD-10-CM codes would be assigned? Would hypertension be coded since headache is a common sign and symptom of hypertension, or would both the headache and hypertension be coded?
A: This will depend on the specifics in the physicians documentation. If the physician treats the headache directly, then you would want to report, along with the hypertension code, the specific type of headache, such as:
- R51, daily chronic headache
- G44.52, new daily persistent headache
If the physician treats only the hypertension, such as adjusting current hypertension drug dosage, expecting that the headache will go away once the hypertension is brought back under control, then you would not need to report it separately.

Migraine With Brainstem Aura
Migraine with brainstem aura is a subtype of migraine with aura in which symptoms clearly originate from the brainstem, but no motor weakness. When motor symptoms are present, the subtype is coded as 1.2.3 Hemiplegic migraine. Originally the terms basilar artery migraine or basilar migraine were used but, since involvement of the basilar artery is unlikely, the term migraine with brainstem aura is preferred in ICHD-3 beta. There are typical aura symptoms in addition to the brainstem symptoms during most attacks. Many patients who have attacks with brainstem aura also report other attacks with typical aura and should be coded for both 1.2.1 Migraine with typical aura and 1.2.2 Migraine with brainstem aura. Many of the symptoms like dysarthria, vertigo, tinnitus, hypacusis, diplopia, ataxia and decreased level of consciousness may occur with anxiety and hyperventilation, and therefore are subject to misinterpretation. Serious episodes of migraine with brainstem aura can lead to stroke, coma, and death. Using triptans and other vasoconstrictors as abortive treatments for migraine with brainstem aura is contraindicated. Abortive treatments for migraine with brainstem aura address vasodilation and restoration of normal blood flow to the vertebrobasilar territory to restore normal brainstem function.

How Are Migraines Diagnosed
To make a diagnosis, your health care provider will
- Take your medical history
- Ask about your symptoms
- Do a physical and neurological exam
An important part of diagnosing migraines is to rule out other medical conditions which could be causing the symptoms. So you may also have blood tests, an MRI or CT scan, or other tests.
Body Location Diagnosis Entry Screen

Coding Migraine in ICD-10-CM
Neurology billing, primary care billing, and emergency room billing are about to become a bit more complicated when patients present with a migraine. Coding Migraine in ICD-10-CM presents a number of challenges to medical coders and billers. The new methodology will require even greater specificity when it comes to assigning codes to healthcare claims, and will have to be supported by the available documentation. When a patient presents with a migraine that needs to be translated into ICD-10 diagnosis code, a total of six characters are needed to reach the greatest degree of specificity in order to create a clean healthcare claim. Migraines fall under the G40-G47 subset of ICD-10-CM codes, Episodic and paroxysmal disorders. By understanding the underlying logic of how ICD-10 is arranged, it is expected that less time will be spent cross-referencing the alphabetic and numeric indices.
Migraine is a neurological disease characterized by recurrent moderate to severe headaches often in association with a number of autonomic nervous system symptoms. Typically the headache affects one half of the head, associated symptoms may include nausea, vomiting, and sensitivity to light, sound, or smell.
Types of Migraine are as follows:
Under ICD-10 methodology, diseases of the nervous system are described by the codes contained between G00 and G99.
There are 44 codes dedicated to ICD-10, describing various types of migraines like:
What Are The Symptoms Of Migraines
There are four different phases of migraines. You may not always go through every phase each time you have a migraine.
- Prodome. This phase starts up to 24 hours before you get the migraine. You have early signs and symptoms, such as food cravings, unexplained mood changes, uncontrollable yawning, fluid retention, and increased urination.
- Aura. If you have this phase, you might see flashing or bright lights or zig-zag lines. You may have muscle weakness or feel like you are being touched or grabbed. An aura can happen just before or during a migraine.
- Headache. A migraine usually starts gradually and then becomes more severe. It typically causes throbbing or pulsing pain, which is often on one side of your head. But sometimes you can have a migraine without a headache. Other migraine symptoms may include
- Increased sensitivity to light, noise, and odors
- Nausea and vomiting
- Worsened pain when you move, cough, or sneeze
Migraines are more common in the morning people often wake up with them. Some people have migraines at predictable times, such as before menstruation or on weekends following a stressful week of work.

Organization Of Migraine Subtypes
The ICHD-3 beta classification includes 6 main subtypes of migraine , most of which are further subdivided. Overall ICHD-3 beta distinguishes 29 migraine subtypes. The following table outlines the main subtypes and their ICHD-1, -2, -3 beta and ICD-10 codes.

New Codes For Headache
The updated code most affecting chiropractic providers for the upcoming year is R51 Headache, which has been deleted and replaced.
Code R51 was the diagnosis code used for headache, with the following approximate synonyms:
-
Cervicogenic headache
There will be two new codes to replace R51:
-
R51.0 Headache with orthostatic component, not elsewhere classified
-
R51.9 Headache, unspecified
**To avoid denial, claims need to be coded to the highest level of specificity.
Orthostatic headache is a condition in which a person develops a headache while vertical, and the headache is relieved when horizontal. Previously, it was often misdiagnosed as different primary headache disorders such as migraine or tension headaches.– Wikipedia
Based on this clarification, the common headache code replacing R51 would be R51.9 headache, unspecified, which would include all the synonyms noted above.
These codes have been modified in the Document Plus software for use on the Clinical Exam and Daily Note Forms.

Used less frequently, but well within the scope of neuromusculoskeletal coding for chiropractors, there are some additions for temporomandibular joint issues. Chiropractors do treat TMJ conditions, which include codes for TMJ disorders M26.601 through M26.603 and sprain and strain of the jaw M26.621 through M26.629 and M26.31 to M26.639. The new additions specifically address arthritis and arthropathy for TMJ:
M26.641 Arthritis of right temporomandibular joint
M26.642 Arthritis of left temporomandibular joint
M26.643 Arthritis of bilateral temporomandibular joint
M26.649 Arthritis of unspecified temporomandibular joint

Electronic medical record data showed migraine is associated with a systematic increase in morbidity across the spectrum of the International Classification of Diseases, Tenth Revision , according to a recently published study in The Journal of Headache and Pain.
Electronic medical record data showed migraine is associated with a systematic increase in morbidity across the entire spectrum of the International Classification of Diseases, Tenth Revision , according to a recently published study in The Journal of Headache and Pain.
Researchers set out to determine overall morbidity and phenotypic diseasome for migraine by analyzing the EMRs of migraineurs who attended Terveystalo, a private healthcare provider in Finland. The retrospective register study included around 17,600 patients with diagnosed migraine between January 2012 and December 2017.
According to the researchers, this study marked the first untargeted approach to investigate the whole ICD-10 coded diseaseome and phenotypic disease networks in migraine patients and is the first study to include a matched cohort population for comparison when constructing PDNs.
Patients were matched with a 1-to-1, age- and gender-matched control population without migraine. The average age of the migraine cohort was 38.9 years, and females accounted for 78.9% of the group.

Acephalgic migraine is a neurological syndrome. It is a variant of migraine in which the patient may experience aura symptoms such as scintillating scotoma, nausea, , hemiparesis and other migraine symptoms but does not experience headache. Acephalgic migraine is also referred to as amigrainous migraine, ocular migraine, ophthalmic migraine or optical migraine, the last three of which are misnomers.
People with acephalgic migraine are more likely than the general population to develop classical migraine with headache.
The prevention and treatment of acephalgic migraine is broadly the same as for classical migraine. However, because of the absence of “headache”, diagnosis of acephalic migraine is apt to be significantly delayed and the risk of misdiagnosis significantly increased.
Visual snow might be a form of acephalgic migraine.
If symptoms are primarily visual, it may be necessary to consult an optometrist or ophthalmologist to rule out potential eye disease before considering this diagnosis.

How Are Migraines Treated
There is no cure for migraines. Treatment focuses on relieving symptoms and preventing additional attacks.
There are different types of medicines to relieve symptoms. They include triptan drugs, ergotamine drugs, and pain relievers. The sooner you take the medicine, the more effective it is.
There are also other things you can do to feel better:
- Resting with your eyes closed in a quiet, darkened room
- Placing a cool cloth or ice pack on your forehead
- Drinking fluids
There are some lifestyle changes you can make to prevent migraines:
- Stress management strategies, such as exercise, relaxation techniques, and biofeedback, may reduce the number and severity of migraines. Biofeedback uses electronic devices to teach you to control certain body functions, such as your heartbeat, blood pressure, and muscle tension.
- Make a log of what seems to trigger your migraines. You can learn what you need to avoid, such as certain foods and medicines. It also help you figure out what you should do, such as establishing a consistent sleep schedule and eating regular meals.
- Hormone therapy may help some women whose migraines seem to be linked to their menstrual cycle
- If you have obesity, losing weight may also be helpful
If you have frequent or severe migraines, you may need to take medicines to prevent further attacks. Talk with your health care provider about which drug would be right for you.

Headache Icd 10 Codes And Guideline:
Most of the commonly used codes for headache comes under categories G43 and G44 which can be found in chapter 6 in ICD-10 CM manual.
- Below are the new codes for headache to be used from October 1st 2020
R51.0 Headache with orthostatic component, NEC
R51.9 Unspecified headache
For both the above codes, migraine is in excludes 2. So, as per the guideline we can code excludes 2 code also if documented in the medical record. But if we see G43 category codes, there is R51.9 in excludes 1. Hence migraine and R51.9 should not be coded together. You need to code only migraine as it is more specified.
- As per ICD coding guidelines routine signs and symptoms of a definitive diagnosis should not be coded separately. Hence if headache is mentioned in the medical record and if it is a common symptom of the diagnosis which we are coding ,remember to avoid coding unspecified headache R51.9
- Menstrual/Pre-menstrual headache should be coded as migraine, menstrual.
Codes and descriptions are given in the below table:
ICD-10 Code |
We will review few examples of headache:
Headache ICD 10 Example 1:
ICD 10 codes for this scenario would be:
- G00.9 Bacterial meningitis
- J44.9- COPD
- I10 Hypertension
Note : Here we do not need to code unspecified headache R51.9 as this is a symptom of meningitis.
Headache ICD 10 Example 2:
CT head was performed and diagnosed migraine with aura.
ICD codes for this scenario would be:
- G43.109 Migraine with aura
Headache ICD 10 Example 3:
- G43.829.
