Migraines are one of the most common neurological conditions affecting millions of individuals worldwide. For healthcare providers and medical coders, accurately documenting and coding migraine diagnoses is essential for appropriate treatment and reimbursement. At Allzone, we specialize in providing expert medical billing and coding services that help streamline processes and maximize revenue. In this blog, we’ll explore everything you need to know about the ICD-10 code for migraine, including coding guidelines, types, documentation tips, and frequently asked questions.
What is a Migraine?
A migraine is a neurological disorder characterized by intense, throbbing headaches often accompanied by symptoms like nausea, vomiting, and sensitivity to light and sound. Unlike common headaches, migraines may last hours or even days and can severely impact a person’s daily life.
Proper diagnosis and documentation are vital, not only for treatment but also for accurate medical coding using ICD-10-CM standards.
What is the ICD-10 Code for Migraine?
The primary ICD-10 code for migraine is:
G43. — Migraine
This parent category includes multiple sub-codes to specify the type and characteristics of the migraine. Accurate documentation allows medical coders to choose the correct sub-code from the following:
Common ICD-10 Codes for Migraine:
- G43.0 — Migraine without aura (common migraine)
- G43.1 — Migraine with aura (classic migraine)
- G43.3 — Hemiplegic migraine
- G43.5 — Persistent migraine aura without cerebral infarction
- G43.6 — Persistent migraine aura with cerebral infarction
- G43.7 — Chronic migraine without aura
- G43.8 — Other migraine
- G43.9 — Migraine, unspecified
Each of these categories can be further specified using additional digits to describe status migrainosus, intractability, and whether or not the patient is experiencing aura.
Why Accurate Migraine Coding Matters
Proper use of ICD-10 migraine codes ensures:
- Timely reimbursement from payers
- Appropriate treatment documentation
- Reduced claim denials and delays
- Better patient care coordination
- Accurate medical records and analytics
At Allzone, we help healthcare providers reduce administrative burdens by offering end-to-end medical billing and coding services that prioritize accuracy and compliance.
Documentation Tips for Coding Migraines
To ensure accurate code assignment, providers should document the following:
- Type of migraine (with or without aura, chronic, hemiplegic, etc.)
- Presence of status migrainosus
- Intractability (whether the migraine is resistant to treatment)
- Laterality (left, right, bilateral, or unspecified)
- Any underlying cause or contributing factors
For example, a chronic migraine without aura, intractable, would be coded as G43.711.

Migraine ICD-10 Coding Scenarios
Here are a few practical examples of how to use ICD-10 codes for migraine:
Scenario 1:
Diagnosis: Migraine without aura, intractable, without status migrainosus
Code: G43.019
Scenario 2:
Diagnosis: Chronic migraine without aura, intractable, with status migrainosus
Code: G43.711
Scenario 3:
Diagnosis: Hemiplegic migraine, not intractable, without status migrainosus
Code: G43.401
These codes must always be backed by proper clinical documentation.
Frequently Asked Questions (FAQs)
What is the general ICD-10 code for migraine?
The general code is G43.9 for “Migraine, unspecified.” However, it’s best practice to use a more specific code when possible.
How do I code a chronic migraine with aura?
Use code G43.111 if it’s intractable and G43.109 if not intractable.
What is status migrainosus?
It refers to a migraine attack that lasts more than 72 hours. This should be captured in the coding if documented, e.g., G43.011 (intractable with status migrainosus).
Can I use G43.9 for all migraine cases?
While G43.9 is acceptable for unspecified migraines, detailed documentation allows for more specific codes, which improves reimbursement and reduces audit risk.
What’s the difference between intractable and not intractable in coding?
Intractable migraines do not respond to standard treatments, while non-intractable migraines do. Coders should review documentation to assign the correct fifth digit.
