AHA Coding Clinic® for ICD-10-CM and ICD-10-PCS - 2021 Issue 4; ICD-10-CM New/Revised Codes
Cervicogenic Headache
A new code (G44.86) was created to specifically capture cervicogenic headache (CGH). A CGH is a type of secondary headache that results from referred pain from the neck that can be due to a variety of conditions. When the associated cervical condition is known and documented, the condition should also be reported as instructed by the “code also” note found at this new code. Pain caused by a CGH typically begins in the neck and the back of the head and radiates towards the front of the head. People with these types of headaches usually...

Article Overview
This article covers the coding and documentation context for cervicogenic headache, including why a new diagnosis code was created, the types of cervical conditions that may be associated with it, and how related conditions may be documented in conjunction with the headache diagnosis. It is relevant to coding professionals, billers, and clinicians who document headache complaints tied to cervical pathology. The article also includes a brief case-based example illustrating the general topic of code assignment without serving as a comprehensive coding reference.
Why This Topic Matters
Cervicogenic headache can be confused with other headache types and may involve underlying cervical diagnoses that affect documentation and coding. Clear recognition of the topic helps support accurate medical record abstraction and diagnosis reporting.
