97140 CPT Code: Manual Therapy Billing Guide

The 97140 CPT code reports manual therapy techniques — joint mobilization and manipulation, manual lymphatic drainage, and manual traction — applied to one or more regions in 15-minute timed units. It is a hands-on, one-on-one service under a plan of care, and its defining billing problem is its relationship with other timed therapy codes: 97140 sits inside a National Correct Coding Initiative edit pair, so how you bill it alongside therapeutic exercise decides whether it gets paid.

What is the 97140 CPT code? 97140 is the Current Procedural Terminology code for manual therapy techniques — such as mobilization, manipulation, manual lymphatic drainage, or manual traction — on one or more regions, billed as a timed service in 15-minute units.

Undeny's Take

The money lost on 97140 is almost entirely a bundling story, not a coverage one. 97140 and therapeutic exercise (97110) form an NCCI edit pair, and payers deny the second code when the two are billed together without a defensible distinct-service modifier. The trap is appending modifier 59 reflexively to clear the edit; that works until an audit asks for the timed minutes proving the two were separate blocks of care. Win these claims the boring way: log start and stop times for each timed service, and apply 59 only when those minutes show real separation.

What 97140 Covers

97140 covers manual therapy techniques delivered with direct one-on-one contact: joint mobilization and manipulation, soft-tissue and manual traction, and manual lymphatic drainage, performed on one or more body regions under a therapy plan of care. It is distinct from therapeutic exercise (97110), which builds strength and range of motion, and from neuromuscular re-education (97112), which retrains movement and balance.

How 97140 Units Are Counted

97140 is a timed code billed in 15-minute units, so the unit count follows total treatment minutes. Under Medicare's 8-minute rule a single unit needs at least 8 minutes, and cumulative timed minutes set the total — roughly 8–22 minutes for one unit, 23–37 for two. Reimbursement follows each payer's fee schedule, with Medicare amounts derived from the code's RVUs on the Physician Fee Schedule. Check your contracted rate or the CPT estimator rather than assuming a national figure.

Modifiers and the 97110 Bundling Edit

GP — service furnished under an outpatient physical-therapy plan of care.
59 / XU — distinct service, applied only when 97140 was genuinely separate from a bundled timed code such as 97110.
KX — attests medical-necessity requirements are met where thresholds apply.

Frequent 97140 Denials

Bundling rejection when billed with 97110 and no distinct-service modifier or supporting minutes.

Frequently Asked Questions

What does the 97140 code cover?

97140 covers manual therapy techniques — joint mobilization and manipulation, manual traction, and manual lymphatic drainage — provided with direct one-on-one contact on one or more regions under a plan of care. It is billed as a timed service in 15-minute units.

Can I bill 97140 and 97110 on the same day?

Yes, but they form an NCCI edit pair, so billing them together requires documentation that they were separate, distinct services and, when the payer expects it, a distinct-service modifier such as 59 or XU. Without that, the second code is denied as bundled.

How many units of 97140 can I bill?

Units depend on total timed minutes under the 8-minute rule: at least 8 minutes for one unit, 23–37 minutes for two, and so on. Document start and stop times for the manual therapy so the unit count is defensible.

Why was my 97140 claim denied with 97110?

The two codes hit a bundling edit. When billed together without a distinct-service modifier and supporting timed minutes, the payer denies one of them. Use modifier 59 only when the services were genuinely separate and the documentation shows it.
