ICD-10 Code R51.9

R51.9 is a billable/specific ICD-10-CM code used for "headache, unspecified."

This code is used when a patient presents with a headache without specific diagnostic characteristics that would classify it under a more specific subtype.

Symptoms include generalized head pain that can vary in intensity, duration, and location, without accompanying diagnostic features.

For billing purposes, R51.9 is appropriate when the healthcare provider documents a headache without specifying the type.

Providers should record symptoms and any related factors or triggers while being mindful that more specific headache codes should be used if diagnostic criteria are met.

Other terms that are coded to R51.9 are “facial pain” and “chronic daily headache.”

Misclassification when more specific headache types can be clinically determined.

R51.9 is used for straightforward cases of unspecified headache, facilitating appropriate treatment and billing.
