Headache

This code signifies the symptom of headache, a common complaint characterized by pain in the head or face. It represents an unspecified headache, where the underlying cause or specific type of headache has not been determined or documented.

Use this code when the medical record documents a headache without further specificity regarding its etiology, type (e.g., migraine, tension), or location. It is appropriate for initial encounters where a definitive diagnosis is pending or when the headache is a transient, isolated symptom.

• Avoid using this code if a more specific headache diagnosis (e.g., migraine, tension headache) is documented.
• Always query the provider for more specific documentation if only "headache" is noted, to allow for more precise coding.
• This code should generally be considered a symptom code and may require an additional code for the underlying condition if known.
