This shift tool checks your two-guest and group care time next to the 25% cap. Type your one-on-one, shared, and group time in the boxes below. You will see your true net shift rate right now.
Input total minutes spent treating one resident at a time. Individual therapy minutes earn 100% clock credit toward your therapist productivity numerator and form the required ≥75% base of total MDS Section O resident treatment minutes.
Enter total resident contact minutes delivered in concurrent sessions (2 residents performing different activities simultaneously in line-of-sight) and group sessions (2 to 6 residents under Medicare Part A performing the same or similar activity).
The engine divides combined non-individual resident minutes (concurrent + group) by total resident therapy minutes to verify compliance with the ≤25.0% CMS PDPM cap, while comparing raw resident contact percentage against weighted therapist clock productivity (50% credit for concurrent, 25% for 4-patient group).
Inputs: Individual 1-on-1: 330 mins | Concurrent Resident Mins: 90 mins (45 mins on therapist clock × 2 residents) | Group Mins: 0 mins | Net Shift: 480 mins
Summing 330 individual minutes and 90 concurrent resident minutes produces 420 total resident therapy minutes reported on MDS Section O. Dividing 90 non-individual minutes by 420 total minutes yields a 21.43% PDPM combined ratio (compliant below the 25.00% cap). On the therapist’s physical clock, 90 concurrent resident minutes required 45 elapsed clock minutes (50% credit), so weighted therapist clock credit equals 330 + 45 = 375 minutes (78.13% weighted clock productivity, vs. 87.50% raw resident contact productivity).
PDPM Non-Individual Share: 21.43% (Compliant ≤ 25%) | Raw Resident Contact Rate: 87.50% | Weighted Therapist Clock Rate: 78.13%
Takeaway: Treating two residents concurrently for 45 clock minutes generates 90 resident treatment minutes on MDS Section O, boosting raw productivity from 78.13% to 87.50% while staying safely below the 25% PDPM ceiling.
Inputs: Individual 1-on-1: 240 mins | Concurrent Resident Mins: 120 mins | Group Mins: 0 mins | Net Shift: 480 mins
When a clinician logs 240 individual minutes and 120 concurrent resident minutes (360 total resident minutes), dividing 120 by 360 produces a 33.33% combined non-individual share, breaching the 25.00% CMS PDPM threshold. Because maximum compliant non-individual minutes equal exactly one-third of individual minutes (240 / 3 = 80 minutes), the caseload carries 40 excess concurrent minutes.
PDPM Non-Individual Share: 33.33% (Non-Compliant > 25% Cap) | Max Allowed Concurrent/Group: 80 mins | Excess Non-Individual Mins: 40 mins
Takeaway: Under the 25% PDPM rule, combined concurrent and group resident minutes can never exceed one-third (33.33%) of your 1-on-1 individual minutes (since 80 / (240 + 80) = 25.00%).
Inputs: Individual 1-on-1: 340 mins | Concurrent Mins: 0 mins | Group Resident Mins: 60 mins (15 clock mins × 4 residents) | Net Shift: 480 mins
A 15-minute group balance class with 4 Medicare Part A SNF residents generates 60 total resident group minutes on MDS Section O (15 mins recorded for each of the 4 residents). Total resident therapy minutes equal 340 + 60 = 400 minutes, putting the PDPM group ratio at 15.00% (60 / 400 ≤ 25%). Weighted therapist clock time equals 340 + (60 / 4) = 355 clock minutes (73.96% weighted clock rate vs. 83.33% raw resident contact rate).
PDPM Group Share: 15.00% (Compliant) | Raw Resident Contact Rate: 83.33% (400 / 480m) | Weighted Clock Rate: 73.96% (355 / 480m)
Takeaway: A single 15-minute 4-resident group session adds 60 resident contact minutes while consuming only 15 minutes of physical therapist clock time.
| Therapy Delivery Mode | Resident Count | Activity Requirement | Therapist Clock Weight | MDS Section O Recording | PDPM Statutory Limit |
|---|---|---|---|---|---|
| Individual (1-on-1) Therapy | 1 resident | Distinct individualized skilled plan of care | 100% (1.00× clock mins) | Full elapsed minutes (100%) | Must comprise ≥ 75% of total discipline minutes |
| Concurrent Therapy | Exactly 2 residents | Different activities simultaneously in line-of-sight | 50% per resident (0.50×) | Full elapsed mins per resident | Combined with Group ≤ 25% of total therapy mins |
| Group Therapy (Part A SNF) | 2 to 6 residents | Same or similar activity simultaneously | 25% per resident (for 4-pt group) | Full elapsed mins per resident | Combined with Concurrent ≤ 25% of total mins |
| Co-Treatment (2 Disciplines) | 1 resident, 2 clinicians | Distinct discipline goals during shared session | Apportioned (sum ≤ session) | Split minutes between disciplines | Total claimed mins cannot exceed session length |
Under the CMS Skilled Nursing Facility Patient-Driven Payment Model (PDPM), combined concurrent and group therapy minutes per discipline may not exceed 25% of a resident’s total therapy minutes.
When CMS transitioned Skilled Nursing Facilities from RUG-IV to the Patient-Driven Payment Model (PDPM), regulators established a strict 25% combined cap on non-individual therapy delivery across physical therapy, occupational therapy, and speech-language pathology. Specifically, for every discipline evaluated over the course of a resident’s Medicare Part A stay, at least 75% of total treatment minutes must be delivered one-on-one, while the sum of 2-resident concurrent minutes plus 2-to-6-resident group minutes cannot exceed 25% of total MDS Section O minutes.
Using our snf concurrent group therapy cap calculator and pdpm 25 percent therapy cap calculator prevents non-compliance audit flags before MDS transmission. A fast mental rule validated by our engine is the One-Third Rule: because 25% of total minutes equals one-third of the remaining 75% individual minutes, your maximum compliant concurrent-plus-group resident minutes always equal Individual Minutes divided by 3.
Concurrent therapy doubles resident contact minutes per elapsed clock minute, creating a mathematical spread between raw MDS contact productivity and physical therapist clock utilization.
Rehabilitation software platforms differ on whether they benchmark clinicians using raw resident contact minutes or weighted therapist clock minutes. When a physical therapist treats Resident A and Resident B concurrently from 10:00 AM to 10:30 AM (30 elapsed clock minutes), both Resident A and Resident B receive 30 minutes of concurrent therapy on MDS Section O (60 total resident contact minutes). If the facility calculates productivity from raw resident contact minutes, those 30 clock minutes contribute 60 minutes toward the numerator, elevating apparent productivity.
If the facility apportions concurrent time by dividing resident minutes by 2 (and 4-resident group minutes by 4), the clinician receives 30 weighted clock minutes of credit. Our concurrent therapy productivity calculator computes both raw resident contact percentage and weighted clock credit percentage simultaneously so rehab directors and treating clinicians can reconcile both scorecards.
Under CMS SNF PDPM rules, the combined total of concurrent therapy minutes (2 residents performing different activities) and group therapy minutes (2 to 6 residents performing the same or similar activity) cannot exceed 25.0% of the total therapy minutes provided to a resident per discipline.
Divide your total 1-on-1 individual therapy minutes by 3. For example, if you deliver 300 minutes of individual 1-on-1 therapy, your maximum allowed combined concurrent and group therapy is 300 / 3 = 100 resident minutes (since 100 / (300 + 100) = 25.00%).
Concurrent therapy is strictly limited to exactly 2 residents treated simultaneously who are performing different activities within the therapist’s direct line of sight. Under Medicare Part A SNF PDPM rules, group therapy is defined as 2 to 6 residents simultaneously performing the same or similar activities.
During 30 clock minutes of concurrent therapy with 2 residents, you generate 60 total resident treatment minutes (30 minutes per resident). In billing systems that credit total resident contact minutes, 30 clock minutes yields 60 billable minutes (200% clock efficiency during that half hour), making it much easier to reach an 85% or 90% SNF productivity target.
CMS audits the 25% cap per resident stay and per therapy discipline (physical therapy, occupational therapy, and speech-language pathology are each tracked separately on MDS 3.0 Section O). However, managing the ratio on every daily shift guarantees that cumulative resident totals never breach 25% at discharge.
Exceeding the 25% combined threshold triggers a non-fatal warning edit on the MDS 3.0 submission and flags the facility for targeted CMS medical review and audit scrutiny if patterns of excessive non-individual therapy persist across caseloads.
