Don't dawdle once you submit your PECOS application form, warns regional home health intermediary NHIC. "Upon submission of an Internet-based PECOS application, please be sure to submit your original signed and dated Certification Statement to the contractor within 15 calendar days of the date on which you submitted your Internet-Based PECOS application," NHIC says in a message to providers. "Incomplete applications may be rejected by the contractor," the RHHI warns.
