B522Z2ZComputerized Tomography (CT Scan) of Intracranial Sinuses using Intravascular Optical Coherence
- Billable / Specific Code
B522Z2Z is a billable ICD-10-PCS procedure code for Computerized Tomography (CT Scan) of Intracranial Sinuses using Intravascular Optical Coherence. It is valid on HIPAA claims for fiscal year 2027 (October 1, 2026 through September 30, 2027). The root operation Computerized Tomography (CT Scan) involves computer reformatted digital display of multiplanar images developed from the capture of multiple exposures of external ionizing radiation. In AHRQ's Clinical Classifications Software (CCSR), this procedure falls under Computerized tomography (CT) without contrast.

Questions About B522Z2Z
Is B522Z2Z a billable code?
Yes. This is a complete seven-character ICD-10-PCS code, specific enough to report Computerized Tomography (CT Scan) of Intracranial Sinuses using Intravascular Optical Coherence on inpatient claims from October 1, 2026 through September 30, 2027.
What do the characters in B522Z2Z mean?
The code breaks down character by character: the 1st character B is the Section (Imaging); the 2nd character 5 is the Body System (Veins); the 3rd character 2 is the Type (Computerized Tomography (CT Scan)); the 4th character 2 is the BodyPart (Intracranial Sinuses); the 5th character Z is the Contrast (None); the 6th character 2 is the Qualifier (Intravascular Optical Coherence); the 7th character Z is the Qualifier (None).
What is the ICD-9-PCS equivalent of B522Z2Z?
Under the General Equivalence Mappings, Computerized Tomography (CT Scan) of Intracranial Sinuses using Intravascular Optical Coherence crosswalks to ICD-9-PCS 38.25 (Intravascular imaging of non-coronary vessel(s) by optical coherence tomography [OCT]). The mapping is approximate, so confirm it fits the documentation.
