CPT 97140
Manual Therapy Techniques, Timed
How it is billed
- Timed in 15-minute units of direct one-to-one contact, counted into the session total under the same eight-minute rule as other timed therapy codes
- Bundled with chiropractic manipulative treatment when performed on the same spinal region on the same day — the manipulation code includes the manual work in that region
- Separately payable where performed on a different region than the manipulation, reported with the modifier identifying the distinct anatomical site
- The generic distinct-service modifier is accepted by most payers, but the specific separate-structure modifier states the actual reason and is the better choice where the payer recognises it
- Applying a distinct-service modifier to clear the edit without a genuinely different region is the pattern that converts a recoverable denial into an audit finding
What the record must show
- The region treated with manual therapy must be named and must differ from the manipulated region for the modifier to be defensible
- The technique performed should be identified — mobilisation, manual traction, lymphatic drainage — rather than recorded as generic manual therapy
- Timed minutes recorded separately from other services in the session, since the unit calculation depends on the split
A worked example
A chiropractor adjusts the lumbar and sacral regions and then performs 15 minutes of soft tissue mobilisation on the cervical spine. The manual therapy is a different region from the manipulation, so it is separately reportable with the modifier identifying the separate structure.
Change the manual therapy to the lumbar region and the answer reverses. It is now the same region as the manipulation, the work is included in the manipulation code, and a modifier does not make it payable — it makes it an unsupported override.
The remittance is the same in both cases at first: a bundling denial on the manual therapy line. The difference is that the first appeals successfully on the note, and the second should never have been billed.
What decides payment
This edit is one of the most consistently mis-handled in outpatient billing, because the fix looks like a modifier and is actually a documentation question. The modifier asserts that services were distinct; only the note can establish that they were, and reviewers read the note rather than the claim.
The specific separate-structure modifier was introduced alongside three others precisely to replace reflexive use of the generic one. Each states why services were distinct — different encounter, different structure, different practitioner, or unusual non-overlapping service — and payer acceptance still varies, so the practice's payer matrix decides which to send.
The volume makes it material. In chiropractic and physical therapy settings the manipulation-plus-manual-therapy combination occurs daily, so a systematic error in either direction — always bundling, or always overriding — compounds across thousands of claims before anyone reviews it.

Questions about CPT 97140
Manual therapy techniques — mobilisation, manipulation, manual lymphatic drainage and manual traction — delivered in direct one-to-one contact and billed in 15-minute units.
Only where the manual therapy was performed on a different spinal region than the manipulation, and reported with the modifier identifying the separate structure. Same region, same day, the manual work is included in the manipulation code.
The separate-structure modifier states the actual reason and is preferred where the payer recognises it. The generic distinct-service modifier is more widely accepted but says less, and neither works without a note documenting the different region.
Because the edit pairs it with same-region manipulation by default. A denial is correct where the regions matched and appealable where they did not — which makes the note, not the modifier, the thing that decides the outcome.
