Summary & Overview

HCPCS G2195: Pediatric Occipital Headache Head Imaging

HCPCS Level II code G2195 denotes diagnostic imaging services intended for pediatric patients presenting with occipital headache where clinical indications support head imaging. Nationally, this code standardizes reporting for a specific indication — occipital headache in children — helping payers and providers align on when imaging is documented for that clinical presentation. Consistent use supports appropriate utilization tracking and clinical documentation for pediatrics-focused imaging decisions.

Key payers included in coverage considerations are Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise briefing on the clinical context for the code, typical sites where the service is delivered, and the common modifiers associated with billing for this service. The publication also outlines what to expect from payer interactions and documentation expectations tied to this indication.

This summary provides national-level context rather than state-specific rules. It aims to help billing professionals, radiology departments, and payer policy teams understand the purpose of G2195, where it is typically used, and the administrative elements that commonly accompany claims for pediatric occipital headache imaging. Data not available in the input will be noted where applicable in downstream sections.

Billing Code Overview

HCPCS Level II code G2195 identifies imaging services ordered for patients with clinical indications for imaging of the head: occipital headache in children. This code is used when a clinician documents clinical signs or symptoms that justify diagnostic imaging focused on the occipital region of the head in pediatric patients.

Service type: Diagnostic head imaging for occipital headache in pediatric patients
Typical site of service: Hospital outpatient imaging centers, emergency departments, and pediatric radiology clinics

Clinical & Coding Specifications

Clinical Context

A 9-year-old child presents to the pediatric emergency department with a 24-hour history of progressive occipital headache after a minor fall during playground play. The child is alert, has intermittent vomiting, and reports neck stiffness. Vital signs are stable but pain is rated 7/10. The pediatric emergency physician performs a focused neurologic exam and documents focal deficits are absent but is concerned for possible intracranial injury or posterior fossa pathology because of worsening headache, vomiting, and recent head trauma. The clinician orders neuroimaging of the head (non-contrast CT or MRI depending on availability and clinical stability) to evaluate for intracranial hemorrhage, skull fracture, or posterior fossa mass.

Clinical workflow:

Triage nurse documents mechanism of injury, onset, and associated symptoms and places the patient on fall precautions.
Emergency physician evaluates, documents history, exam, and clinical indications for imaging (occipital headache, vomiting, concern for intracranial injury).
Radiology is contacted; modality decision made (CT if acute trauma/unstable or CT faster; MRI if stable and concern for posterior fossa lesion or need for detailed posterior fossa imaging).
Imaging performed with pediatric protocols; sedation arranged if the child cannot remain still for MRI.
Radiologist interprets images and issues an urgent report; findings are communicated to the ordering clinician.
Treatment plan (observation, neurosurgical consult, discharge with follow-up) is documented and coded for billing using the HCPCS Level II code G2195 to indicate imaging service for patients with clinical indications for head imaging for occipital headache in children.

Coding Specifications

Modifier	Description	When to Use
`22`	Increased procedural services	When work required is substantially greater than typically required for the imaging service (document justification).

23 | Unusual anesthesia | When general anesthesia is medically necessary for the imaging procedure (commonly for MRI in children).

52 | Reduced services | When the imaging study is partially reduced or not completed as planned.

53 | Discontinued procedure | When the imaging study is started but discontinued due to patient instability or other clinical reasons.

56 | Preoperative assessment only | When imaging is performed solely for preoperative evaluation and no subsequent procedure by the same provider occurs (rare for imaging codes).

62 | Two surgeons | When two qualified practitioners of different specialties are required (rare for imaging but may apply when interventional or surgical planning requires joint documentation).

AS | Physician assistant, nurse practitioner, or clinical nurse specialist services furnished in part-time | When an advanced practice clinician provides a portion of the service under applicable state rules (billing nuances vary by payer).

CO | Cast room services | When services relate to cast application or management in facility settings (included here for pediatric injury care workflows involving head/neck immobilization).

QK | Medical direction of two or more CRNAs by a physician | When physician directs multiple CRNAs for anesthesia during imaging (MRI) in children.

QX | CRNA service independent | When a CRNA provides anesthesia without physician direction for imaging sedation.

Taxonomy Code	Specialty	Notes

G44.209 | Tension-type headache, unspecified, not intractable | Common pediatric headache diagnosis; imaging may be used to exclude secondary causes if red flags exist.

M54.2 | Cervicalgia | Neck pain or stiffness accompanying occipital headache may prompt imaging to evaluate cervical spine or referred pain sources.

R11.2 | Nausea with vomiting, unspecified | Associated symptom that increases concern for intracranial process when occurring with occipital headache.

G93.1 | Anoxic brain damage, not elsewhere classified | Included as a high-acuity differential that imaging aims to exclude in severe presentations.
