CPT 0609T: Spinal Magnetic Resonance Spectroscopy for Discogenic Pain

CPT code 0609T designates magnetic resonance spectroscopy (MRS) of at least three spinal discs (cervical, thoracic, or lumbar) using single‑voxel acquisition to quantify biochemical markers that inform disc structural integrity and the diagnosis of discogenic pain. This advanced diagnostic imaging code captures anatomic and metabolic data beyond standard MRI and is relevant to clinicians evaluating chronic axial spine pain where discogenic origin is suspected.

Key payers in national coverage discussions include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of what CPT code 0609T represents, the typical clinical context for ordering MRS of multiple discs, common sites of service, and the payer landscape relevant to national reimbursement and coverage policy. The publication also provides benchmarks and policy updates where available, and situates the code within clinical workflows for spine pain evaluation.

This summary serves clinicians, imaging departments, and billing professionals seeking a national perspective on the clinical intent and payer relevance of CPT code 0609T.

Billing Code Overview

CPT code 0609T describes magnetic resonance spectroscopy (MRS) of the spine, performed on at least three intervertebral discs in the cervical, thoracic, or lumbar regions. The procedure uses single‑voxel acquisition to measure biochemical markers per disc, assessing disc structural integrity and assisting in the diagnosis of discogenic pain.

Service Type: Diagnostic imaging — advanced spinal spectroscopy

Typical Site of Service: Hospital outpatient imaging center or freestanding outpatient imaging facility, where magnetic resonance equipment and specialized spectroscopy capability are available.

Clinical Context

A 46-year-old patient with chronic axial neck and/or low back pain unresponsive to conservative care (physical therapy, NSAIDs, epidural steroid injections) is referred for diagnostic evaluation of suspected discogenic pain. The patient reports persistent deep, centralized pain with intermittent radicular symptoms but prior imaging (MRI without spectroscopy) showed degenerative disc disease without clear nerve root compression. The ordering spine specialist documents clinical need to assess biochemical markers of intervertebral disc integrity to differentiate painful disc degeneration from other pain generators.

The clinical workflow: The patient undergoes preauthorization as required by the payer, screening for MRI contraindications (ferromagnetic implants, pacemaker, severe claustrophobia). On the day of service, informed consent is obtained. The patient is positioned in the MRI scanner. The technologist and interpreting physician perform magnetic resonance spectroscopy (MRS) with single-voxel acquisition of at least three discs in the cervical, thoracic, or lumbar region per the procedure description. Image acquisition targets biochemical markers (for example, proteoglycan content, choline, lactate) to assess structural integrity. The interpreting radiologist or neuroradiologist generates a report correlating spectroscopic findings with morphologic MRI sequences and provides an impression regarding likelihood of discogenic pain. Results are incorporated into the treating physician’s care plan, which may include targeted interventions (e.g., intradiscal therapies, surgical consultation) based on spectroscopic evidence of painful disc degeneration.
