AHA Coding Clinic® for ICD-10-CM and ICD-10-PCS - 2020 Quarter 4; New/Revised ICD-10-CM Codes
Intracranial Hypotension
A 35-year-old woman was admitted with a two-month history of headaches, occasionally accompanied by nausea, vomiting, and vertigo. The chronic daily headache is worse in the upright position, but gets better when lying down. She also had a negative history of lumbar puncture, trauma, or manipulation. Magnetic resonance imaging (MRI) showed meningeal enhancement. She was discharged with the diagnosis of positional headache due to spontaneous intracranial hypotension. What is the appropriate code assignment for positional headache due to spontaneous intracranial hypotension? ...

Article Overview
This Coding Clinic article covers ICD-10-CM guidance for intracranial hypotension and related nervous system disorders. It explains newly created and expanded diagnostic categories, discusses associated neurologic complications that may also need to be reported, and presents a clinical scenario involving positional headache in the setting of spontaneous intracranial hypotension. The article is relevant to coding professionals, CDI staff, and clinicians who document neurologic and cerebrospinal fluid leak-related conditions.
Why This Topic Matters
Intracranial hypotension can be overlooked, yet it may be documented with related neurologic complications and postprocedural conditions that affect diagnosis coding. This article helps readers understand the scope of the updated ICD-10-CM guidance and the kinds of clinical documentation that may be relevant when this condition is present.
Article Sections
-
ICD-10-CM code updates for intracranial hypotension
Introduces the updated diagnostic coding structure for intracranial hypotension and a related central nervous system disorder category. The section also notes additional codes created for postprocedural nervous system complications.
-
Associated conditions and clinical context
Describes the broader clinical context of intracranial hypotension, including common categories of causes and related neurologic conditions that may coexist. It also summarizes the general sequencing concept referenced in the tabular guidance.
-
Clinical example
Presents a patient scenario involving positional headache and spontaneous intracranial hypotension, followed by the code assignment discussed in the article.
