Summary & Overview
CPT 0612T: MRS Spine Biomarker Interpretation and Report
CPT code 0612T designates the interpretation and reporting of biomarker data derived from magnetic resonance spectroscopy (MRS) of the cervical, thoracic, or lumbar spine for software analysis. This code captures a software-driven diagnostic service that converts MRS measurements into biomarkers and produces an interpretive report, distinguishing it from technical image acquisition codes. Its adoption matters nationally as imaging centers and radiology groups integrate advanced post-processing and quantitative reporting into spinal MRS workflows, affecting coding, billing, and clinical documentation practices.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise presentation of the code's clinical scope, typical sites of service, and the service type. The publication provides benchmarks and policy-relevant context where available, highlights common billing modifiers, and explains implications for coding workflows and claims submission. It also summarizes clinical context for MRS-based spinal biomarker interpretation to clarify where this code is applicable.
This national overview is intended for coding professionals, radiology administrators, and compliance teams seeking a clear, policy-focused description of CPT code 0612T, its role in spinal MRS reporting, and practical considerations for integrating the code into billing operations.
Billing Code Overview
CPT code 0612T reports the interpretation and report of biomarker data from magnetic resonance spectroscopy (MRS) of the cervical, thoracic, or lumbar spine for software analysis. This service represents analysis and generation of an interpretive report from MRS-derived biomarker datasets rather than image acquisition alone.
Service type: Diagnostic image data interpretation and software-based biomarker analysis
Typical site of service: Hospital outpatient imaging departments, ambulatory imaging centers, and specialty radiology clinics

Clinical & Coding Specifications
Clinical Context
A 58-year-old patient with chronic neck pain and progressive lower extremity weakness is referred for advanced spinal assessment. The ordering spine specialist requests magnetic resonance spectroscopy (MRS) of the cervical spine to evaluate biomarker profiles within a suspicious intramedullary lesion identified on conventional MRI. Imaging technologists acquire the MRS data during the MRI exam at an outpatient radiology center or hospital imaging department. A board-certified neuroradiologist processes the spectroscopy dataset using specialized software to derive quantitative biomarker metrics and interprets the spectroscopy results. The neuroradiologist generates a formal interpretation and report of the biomarker data, documenting metabolite ratios and any findings that support tumor, demyelination, inflammation, or ischemia. Billing for the interpretation and reporting of the MRS-derived biomarker data is reported with 0612T. Typical sites of service include outpatient hospital imaging departments, freestanding radiology centers, and hospital outpatient clinics.
Coding Specifications
| Modifier | Description | When to Use |
|---|---|---|
22 | Increased procedural services | Use when the interpretation required substantially greater work than typically required, documented in the report. |
23 | Unusual anesthesia | Use when general anesthesia was medically necessary for the MRI/MRS interpretation encounter. |
52 | Reduced services | Use when the spectroscopy interpretation/reporting service was partially reduced or not completed as planned. |
53 | Discontinued procedure | Use when the acquisition was started but stopped before completion and interpretation/report was limited. |
62 | Two surgeons | Use when two physicians of different specialties share responsibility for interpretation and both document their roles. |
AS | Physician assistant, nurse practitioner, or clinical nurse specialist services for assistant at surgery | Use when an advanced practice provider formally assists in the imaging encounter per payer rules and modifier is required. |
CQ | Service furnished by a physical therapist in a CMS demonstration project | Rarely applicable; use only if interpretation/reporting is furnished under a qualifying demonstration by a physical therapist. |
QK | Medical direction of two, three, or four qualified individuals | Use when the physician directed multiple qualified individuals who performed portions of the service and documentation supports medical direction. |
QX | CRNA service with medical direction by physician | Use when a certified registered nurse anesthetist provided anesthesia services under physician medical direction for the imaging encounter. |
QY | Medical direction of one CRNA by a physician | Use when the physician medically directed one CRNA during the anesthesia care for the imaging session. |
SH | Speech-language pathology services provided under a rehabilitative services plan | Generally not applicable but included in modifier list; use only if spectroscopic reporting is part of a speech pathology rehabilitation program requiring modifier. |
SJ | Prosthetic/orthotic services provided under a rehabilitative services plan | Uncommon for this code; use only if interpretation directly ties to prosthetic/orthotic management and payer requires modifier. |
TC | Technical component | Use when billing only the technical component of the service; for 0612T this would apply if facility bills the software processing/technical portion separately. |
