Headache with orthostatic component, NEC

This code describes a headache that is significantly influenced by changes in body position, particularly when moving from a lying or sitting to a standing position (orthostasis). The headache typically worsens upon standing and improves upon lying down, and its etiology is not attributable to another specific, classified condition.

Use this code for patients presenting with headaches clearly exacerbated by orthostatic changes, where other causes like postural orthostatic tachycardia syndrome (POTS), cerebrospinal fluid (CSF) leaks, or medication side effects have been ruled out or are not the primary diagnosis. Documentation should explicitly link the headache to positional changes and note the absence of a more specific underlying cause.

• Ensure documentation specifies the orthostatic component of the headache.
• Do not use if a more specific cause for the orthostatic headache (e.g., CSF leak, POTS) has been identified and can be coded.
• Consider sequencing this code after any underlying conditions if they are contributing factors but not the direct cause of the orthostatic component.
