Therapy Billing Calculators

Use these tools to estimate therapy billing units, productivity, utilization, documentation time, and related workflow measures. These calculators are designed for PT, OT, and SLP workflows and are informational only. Always confirm payer rules, facility policy, and documentation requirements before billing.

Billing units and 8-minute rule

If you need to convert timed therapy minutes into billing units, start with the Billing Units Calculator. If you need the rule explanation, thresholds, examples, and source references, use the CPT 8-Minute Rule Helper.

Productivity and workday planning

If you are trying to understand how many billable minutes are needed to meet a productivity target, use the Therapist Productivity Calculator. If your day includes an unpaid lunch break, use the lunch break version. For concurrent or group scenarios, try the Concurrent Therapy Productivity Calculator.

Utilization, caseload, and documentation

Productivity, utilization, caseload, and documentation time measure related but different parts of the workday. Use these tools when the question is about scheduled time, non-billable documentation, or realistic workload capacity rather than direct billing units.

Benchmarks by setting

Therapy productivity expectations vary by setting. These benchmark pages provide context for SNF, outpatient, and home health therapy productivity.

Important billing note

These tools are informational and are not billing, legal, compliance, or payer-specific advice. Medicare, Medicaid, commercial payers, state programs, and facility policies may apply different rules. Confirm final billing decisions with the payer, your compliance team, or your facility’s policy.
