97012: Mechanical traction

Category: Supervised modality

What 97012 covers

A supervised, untimed modality code for mechanical traction, most commonly intersegmental or roller table traction in chiropractic settings.

How it works in a chiropractic practice

One unit per visit, no time requirement, no one on one requirement: the patient on the traction table while staff work nearby is exactly what the code describes. Because it is easy to run on every patient, some payers watch its frequency; a practice whose every visit includes 97012 for months per patient invites utilization review, and some plans cap or exclude it.

What the note must show

A worked example

A patient gets fifteen minutes on the intersegmental table before an adjustment. That is one unit of 97012 regardless of the fifteen minutes. A biller who reads the clock and bills two units has invented a unit; the code is untimed and always one per visit.

Medicare rules

Not payable to chiropractors under Medicare. Commercial plans commonly cover it but several exclude passive modalities after a set visit count in a care episode.

Where practices get burned

Billing multiple units; running it on every visit without clinical rationale as plans expect active care to progress; assuming coverage on plans that exclude passive modalities late in care.

How Cervica helps with 97012

Cervica's claim scrubber validates modifiers, units, and diagnosis pointers for 97012 before submission, per payer rules handle code substitutions and modifier requirements automatically, and when a payer pushes back anyway the denial worklist reads the adjustment codes and routes the claim to the exact fix.
