Your patient’s dates

Enter the first treatment day.

Recertify sooner if the plan of care ends before 90 days or changes significantly. If a certification is late, Medicare accepts a delayed certification with an explanation of the delay.

Why these dates cause denials

Missing certifications and progress reports are among the documentation errors CMS lists for outpatient therapy. In a 2018 audit, the HHS Office of Inspector General found that 61% of sampled outpatient physical therapy claims did not meet Medicare requirements. Read the OIG report.

Questions

When must a therapy plan of care be certified?

CMS considers certification timely when the physician or non-physician practitioner signs the plan within 30 days of the first treatment day. A late certification can still be accepted with an explanation of the delay.

How often must a plan of care be recertified?

At least every 90 calendar days, or sooner when the plan ends before then or when it changes significantly.

How often is a progress report required?

At least once every 10 treatment days. A treatment day is a day on which a billable therapy service is provided.

Do verbal orders need a signature?

Yes. CMS asks that verbal orders be documented and signed by the ordering practitioner within 14 days.
