97110 vs 97112: Therapeutic Exercise vs Neuromuscular Re-ed
97110 vs 97112: exercise builds strength and motion, neuromuscular re-education retrains balance and control. Documentation, Medicare rates, units and MUEs.
On this page 9 sections
CPT 97110 (therapeutic exercise) builds strength, range of motion, flexibility and endurance. CPT 97112 (neuromuscular re-education) retrains how the nervous system controls movement: balance, coordination, posture, and the sense of where the body is in space. If the session improves what a muscle or joint can do, it's 97110; if it improves how well the patient controls and stabilizes movement, it's 97112.
Key takeaways
- 97110 targets capacity (force, range, endurance). 97112 targets control (balance, coordination, proprioception, postural stability).
- Both are timed, one-on-one, 15-minute codes with GP, counted together under the 8-minute rule. CMS's own unit-counting examples use exactly this pair.
- 97112 pays more per unit than 97110 on the Medicare fee schedule. The note has to show the neuromuscular deficit and the retraining, not just exercises done standing on foam.
- No NCCI edit pairs 97110 with 97112. Their daily MUEs differ: 6 units for 97110, 4 for 97112.
- Chiropractic manipulation and group therapy do bundle 97112; see the NCCI section.
Therapeutic exercise vs neuromuscular re-education at a glance
| 97110 therapeutic exercise | 97112 neuromuscular re-education | |
|---|---|---|
| Aimed at | Strength, range of motion, flexibility, endurance | Balance, coordination, kinesthetic sense, posture, proprioception |
| Typical patients | Post-surgical deconditioning, weakness, stiffness, tendinopathy | Stroke, Parkinson's disease, neuropathy, vestibular or balance deficits, falls, post-sprain instability |
| Typical interventions | Resisted exercise, stretching, ergometer, progressive loading | Perturbation training, single-leg stance with challenge, weight-shifting, PNF patterns for control, proprioceptive drills |
| Measures that show change | Manual muscle test grades, goniometry, repetitions, workload | Berg Balance Scale, timed tests, sway, single-leg stance time, fall frequency |
| Units and modifiers | Timed, 15 minutes, GP | Timed, 15 minutes, GP |
| Medicare MUE per day | 6 | 4 |
Patients, interventions and measures in the table are common examples in our own words, not code requirements.
The difference in plain language
Exercise and re-education often use the same props: a balance board, a step, a resistance band. The test is the impairment the session is treating.
- 97110 fixes the engine. The quadriceps can't produce enough force to climb stairs, the shoulder lacks the range to reach a shelf. Exercises load the tissue and progress the load.
- 97112 fixes the steering. The patient has the strength but can't stay upright when the ground moves, overshoots a target, or doesn't feel where the foot is. Training challenges the balance and sensory systems and makes the patient correct.
A standing heel raise in sets of 15 for calf strength is 97110. Single-leg stance on foam with eyes closed, catching a ball while the therapist perturbs the trunk, in a patient with a documented balance deficit, is 97112. Doing the heel raises on foam doesn't turn them into 97112; the purpose and the deficit do.
Documentation for each code
Each treatment note must identify every intervention "in language that can be compared with the billing on the claim" and record total timed code minutes and total treatment time (Benefit Policy Manual, ch. 15, §220.3.E). For these two codes that means:
- 97112: name the deficit (balance, coordination, proprioception, posture), the retraining techniques, how the challenge was progressed, the cueing or assistance needed, and the objective measure you're tracking. Tie it to a goal such as fall reduction or safe community ambulation.
- 97110: name the impairment, the exercises and parameters, the progression, and the skilled element: why a therapist was needed rather than a home program.
Progress reports at least every 10 treatment days should show the measures moving (§220.3.D). Balance scores that don't change for weeks, with 97112 billed every visit, are hard to justify.
Medicare rates for 97110 and 97112
97112 carries slightly more work and practice-expense RVUs than 97110, so it has the higher national allowed amount per unit:

97110 vs 97112: Medicare rates
On a claim, the multiple procedure reduction narrows the gap: the unit with the highest practice expense is paid in full and the rest lose half their practice expense (Claims Processing Manual, ch. 5, §10.7). The calculator below prices a typical balance-and-strength visit:

Same-day therapy units after the practice-expense reduction
Commercial and workers' comp payers often price PT as a percentage of these Medicare amounts, so the relationship between the two codes usually carries into other contracts. Download both codes at your locality from the PT fee schedule or compare a contract with the contract check.
Units: CMS's own examples use this pair
The Claims Processing Manual's 8-minute-rule examples are built on 97112 and 97110 (ch. 5, §20.2):
- Example 1: 24 minutes of 97112 and 23 minutes of 97110 total 47 minutes, which is 3 units. Each code gets at least one; the extra unit goes to 97112, which had more time. Bill 2 units of 97112 and 1 of 97110.
- Example 2: 20 minutes of each, 40 total, is 3 units. With equal time, either code takes 2 units and the other 1. "Do not bill 3 units for either one of the codes."

NCCI edits and modifier 59 with 97110 and 97112
There's no procedure-to-procedure edit between 97110 and 97112 in the current practitioner or hospital tables (NCCI PTP edits, version 32.3, effective October 1, 2026). Billing both needs no 59 or X modifier, only separate minutes: NCCI policy says not to report two physical medicine services for the same 15-minute period (NCCI Policy Manual, ch. XI, §P.2).
Edits that do involve these codes:
| Other code on the same date | Edit | What to do |
|---|---|---|
| 97150 group therapy | 97150 column 1; 97110 and 97112 column 2; indicator 1 | Only if the individual and group services were in separate time blocks; the modifier goes on 97110 or 97112 |
| 97113 aquatic therapy | 97113 column 1, 97110 column 2, indicator 1 | Separate time blocks only |
| Chiropractic manipulation 98940–98942 | CMT column 1, 97112 column 2, indicator 1 | Not payable in a spinal region being manipulated; different region with 59 or XS, and only for a provider eligible to bill therapy codes to Medicare (ch. XI, §S) |
When separate time blocks justify bypassing an indicator-1 edit between timed codes, CMS's modifier booklet uses 59 or XE (MLN1783722) and the NCCI Policy Manual says 59 or XU (ch. XI, §P.2). Use the one your contractor accepts; see modifier 59.
Common mistakes
- Billing 97112 for any exercise done standing. Balance demand alone isn't neuromuscular re-education; the deficit and the retraining have to be documented.
- Billing 4+ units of 97112. The practitioner MUE is 4 per day; more is denied for the line.
- One block of time, two codes. A combined strength-and-balance circuit is billed under the code that describes most of each 15-minute interval, not both.
- No objective balance measure. Without one, progress reports can't show that 97112 is still needed.
- Missing GP, CQ or KX. GP on every line, CQ when a PTA furnished more than 10% of the service, KX above the yearly threshold.
FAQ
What is the difference between 97110 and 97112?
97110 is therapeutic exercise to develop strength, endurance, range of motion and flexibility. 97112 is neuromuscular re-education of movement, balance, coordination, posture and proprioception. Pick the one that matches the deficit being treated and the documented purpose of the session.
Can 97110 and 97112 be billed together?
Yes. There's no NCCI edit between them, so no modifier is needed. Each needs its own minutes, and the day's total timed minutes cap the units. CMS's 8-minute-rule examples use this exact pair.
Does 97112 pay more than 97110?
Yes, slightly, per unit on the Medicare fee schedule; the comparison above shows the current amounts. The difference shrinks on multi-unit visits because of the therapy multiple procedure reduction.
Is balance training 97110 or 97112?
Balance training for a documented balance, coordination or proprioceptive deficit is 97112. Strengthening that happens to be done standing is still 97110.
How many units of 97112 can be billed per day?
Medicare's practitioner MUE for 97112 is 4 units per date of service. For 97110 it's 6.
