Migraines are one of the most common neurological conditions affecting millions of individuals worldwide. For healthcare providers and medical coders, accurately documenting and assigning migraine ICD 10 codes is essential for proper treatment and reimbursement. At Allzone, we specialize in providing expert medical billing and coding services that help streamline processes and maximize revenue. In this comprehensive guide, we’ll explore everything you need to know about the ICD 10 code for migraine, including coding guidelines, types, documentation tips, and FAQs.
What is a Migraine?
A migraine is a neurological disorder characterized by intense, throbbing headaches often accompanied by nausea, vomiting, and sensitivity to light or sound. Unlike common headaches, migraines can last hours or days, severely impacting daily life.
For accurate billing and clinical documentation, providers must assign the correct ICD 10 migraine code that reflects the type, severity, and associated symptoms.
What is the ICD-10 Code for Migraine?
The primary migraine ICD10 category is:
G43 — Migraine
This diagnostic category contains several subcodes to specify the exact type of migraine. Proper documentation helps coders choose the correct migraine ICD 10 code from the following commonly used subcategories.
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 ICD 10 (chronic migraine without aura)
-
G43.8 — Other migraine
-
G43.9 — ICD 10 migraine unspecified
-
Each category may include additional digits to indicate intractability or status migrainosus. For example, G43.711 represents chronic migraine without aura, intractable, with status migrainosus.
Why Accurate Migraine Coding Matters
Using the correct ICD 10 migraines codes ensures:
-
-
Faster reimbursement
-
Accurate clinical documentation
-
Fewer claim denials
-
Better patient outcomes
-
Strong compliance with payer guidelines
-
Allzone supports healthcare providers with precise neurological coding and complete migraine documentation to avoid payer rejections.
Documentation Tips for Accurate Migraine ICD-10 Coding
To ensure accurate code assignment, clinical notes should include:
-
Type of migraine (with or without aura, chronic, hemiplegic, etc.)
-
Presence of status migrainosus
-
Intractability (intractable vs. not intractable)
-
Laterality
-
Severity, triggers, or contributing factors
Example:
A provider documents chronic migraine without aura, intractable, with status migrainosus → code G43.711.

Migraine ICD-10 Coding Scenarios
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 examples highlight the importance of correct migraine ICD 10 code selection based on clinical detail.
Frequently Asked Questions (FAQs)
1. What is the general ICD-10 code for migraine?
The general code is G43.9, which is ICD 10 migraine unspecified.
2. How do I code a chronic migraine with aura?
Use the correct chronic migraine ICD 10 subcode, such as G43.111 (intractable) or G43.109 (not intractable).
3. What is status migrainosus?
It refers to a migraine attack lasting longer than 72 hours. Example: G43.011 (intractable with status migrainosus).
4. Can I use G43.9 for all migraines?
It is allowed, but more specific codes improve reimbursement accuracy and reduce audit risk.
5. What’s the difference between intractable and not intractable?
Intractable migraines don’t respond to standard treatment; non-intractable migraines do. Documentation must clarify this for correct coding.
6. How does Allzone help with migraine coding?
Allzone provides expert coding audits, claim review support, and accurate assignment of ICD 10 migraine codes to reduce rejections.
