5.1 Supervision and Delegation

Key Takeaways

  • The PT retains the initial evaluation, periodic reevaluation, discharge, record-completeness, and billing-accuracy responsibilities.
  • A PT may supervise no more than three assistive-personnel providers at once; if supervising three, at least one must be a PTA.
  • No more than two PTAs may be under general supervision, and each must first complete 2,000 hours of patient care under on-site supervision as a licensed PTA.
  • For a generally supervised patient, the PT reevaluates and provides and documents intervention every fourth treatment visit or every 30 days, whichever comes first.

Supervision and Delegation

A.R.S. § 32-2043 and R4-24-303 assign responsibility to the PT while allowing appropriate delegation. The exam usually asks who may perform a task, which supervision level applies, or whether a frequency or ratio has been exceeded.

Responsibilities retained by the PT

The PT is responsible for the initial evaluation, periodic reevaluation, discharge, completeness of the patient record and accuracy of billing. On each date of service, the PT performs and documents any intervention that requires PT expertise. The PT decides whether to delegate based on the patient's acuity and plan of care and the assistant's or aide's education and training.

Delegation is permitted only when the PT determines the person has the education and training to perform the task safely, effectively and efficiently. A facility policy cannot compel a PT to delegate an inappropriate task, and the presence of supervision does not transform a PT-only responsibility into an assistive task.

Numerical limit

A PT may supervise no more than three assistive personnel at one time. If the PT supervises three, at least one must be a PTA. Because PT and PTA students are excluded from the definition of assistive personnel, they do not count in the three-person calculation, although they still require on-site supervision. Interim permit holders also require on-site supervision under their permit and rules.

No more than two PTAs may be under general supervision at one time. Assistive personnel who do not qualify for general supervision remain under on-site supervision.

When a PTA qualifies for general supervision

Before working under general supervision, the person must be a licensed PTA and must have completed at least 2,000 hours of patient care as a PTA under on-site supervision. Until that threshold is met, on-site supervision is required.

General supervision means the PT is on call and readily available by telecommunications. Board definitions make those terms measurable: the PT can respond within 15 minutes and can go to the location the same day after consultation if the PT determines that doing so is in the patient's best interest. General supervision can use telehealth, but a text message answered hours later is not “readily available.”

Required PT contact under general supervision

For a patient treated by a PTA under general supervision, the supervising PT must reevaluate the patient and provide and document the therapeutic intervention on that date at least every fourth treatment visit or every 30 days, whichever occurs first. The clock can be triggered by visits before the calendar interval. A PT's review of the PTA note alone does not substitute for the required PT service.

The requirement attaches to general supervision. Do not automatically impose it as a universal reevaluation schedule for every patient. Independently, R4-24-304 requires reevaluation when the patient is not progressing as reasonably expected or when progress warrants a change in the plan of care.

General-supervision documentation

The generally supervised PTA's record includes the supervising PT's name and license number, patient identification, date, intervention provided, and information about consultation with the supervising PT. Arizona statute allows a PTA to document care provided under a compliant arrangement without a routine PT co-signature. A co-signature policy may be an employer choice, but it is not the legal basis for delegation.

Example

A qualified PTA treats three times in a week under general supervision after the PT's initial evaluation. On the fourth treatment visit, the PT must perform the required reevaluation and intervention even if 30 days have not passed. If the PTA reports a sudden material change before then, the PT applies clinical judgment and the record rule; waiting for visit four is not appropriate when reevaluation is already indicated.

Official anchors

Ratio and frequency drill

One PT supervises two qualified PTAs by general supervision and one aide on site. The total assistive-personnel count is three, at least one is a PTA, and no more than two PTAs use general supervision. The structure can satisfy the numerical rules, but every individual delegation still depends on patient acuity, plan of care and worker competence. Ratios are ceilings, not a presumption that every assignment is safe.

For a patient treated weekly, 30 days may arrive before the fourth treatment visit. For a patient treated three times per week, the fourth visit arrives first. The PT applies whichever occurs first and records the reevaluation and intervention that day. A sudden unexpected decline can independently trigger earlier reevaluation, so the recurring interval is not permission to wait.

General supervision also must work in reality. A nominal supervisor who cannot answer within 15 minutes or cannot go to the site the same day when the PT determines it is needed does not satisfy the defined availability simply because a phone number appears in the chart.
