Question 1

Does every clinician need their own NPI?

Accepted Answer

Each individual clinician in this workflow needs a Type 1 NPI. The practice Type 2 NPI does not replace the individual identifier.

Question 2

What's the difference between Type 1 and Type 2 NPI?

Accepted Answer

Type 1 identifies an individual health care provider. Type 2 identifies an organization such as a group practice.

Question 3

Can the practice apply for the clinician's NPI?

Accepted Answer

NPPES permits an authorized employee or surrogate to help apply for another individual through its authorized workflow. Each person uses their own access; never ask for the clinician’s I&A password.

Question 4

Does an NPI mean you're enrolled in Medicare?

Accepted Answer

No. An NPI is an identifier. Medicare enrollment and reassignment are separate CMS approval processes.

Question 5

What is PECOS?

Accepted Answer

PECOS is the CMS electronic system used to submit and manage Medicare provider and supplier enrollment information.

Question 6

What is CMS I&A?

Accepted Answer

CMS Identity & Access verifies identity and controls who may use systems such as NPPES and PECOS.

Question 7

Does the clinician have to complete PECOS themselves?

Accepted Answer

The clinician remains responsible for accurate enrollment information and required signatures. An appropriately authorized user may perform permitted work through CMS access relationships.

Question 8

Can the clinic complete PECOS for them?

Accepted Answer

An appropriately authorized practice user may complete permitted PECOS work using CMS-authorized access. The clinician must not share a password and still completes required attestations or signatures.

Question 9

Can I use the clinician's PECOS password?

Accepted Answer

No. Each person should use their own CMS identity. Use the current Staff End User, Surrogate, employer, or other applicable I&A relationship instead.

Question 10

What is surrogate access?

Accepted Answer

For this scenario, it is the CMS I&A connection that authorizes the practice organization to perform selected business functions for the clinician. A practice user then needs the appropriate staff access.

Question 11

What is a Staff End User?

Accepted Answer

A Staff End User is a person granted access by an individual provider or an organization’s Authorized Official or Access Manager to perform selected work. Staff End Users cannot manage connections or sign an application for another person.

Question 12

What is CMS-855I?

Accepted Answer

CMS-855I is the Medicare enrollment application for physicians and eligible non-physician practitioners. PECOS presents the electronic enrollment workflow.

Question 13

Do I still use CMS-855R?

Accepted Answer

No. CMS discontinued CMS-855R and incorporated reassignment actions into CMS-855I and PECOS.

Question 14

What is a PTAN?

Accepted Answer

A PTAN is a Medicare enrollment identifier associated with an approved Medicare enrollment. Handle it as sensitive credentialing information.

Question 15

Is PTAN the same as NPI?

Accepted Answer

No. The NPI is a permanent national identifier; the PTAN is tied to Medicare enrollment.

Question 16

How do I check Medicare enrollment status?

Accepted Answer

Use PECOS and the official status or contact methods supplied by CMS and the applicable MAC. For the supported Texas Part B path, use Novitas provider-enrollment resources.

Question 17

What does reassignment mean?

Accepted Answer

It connects an individually enrolled clinician with an eligible enrolled organization so the organization may bill and receive Medicare payment for covered services furnished through it.

Question 18

Who receives the Medicare payment?

Accepted Answer

When a valid reassignment applies, the eligible billing organization generally submits the claim and receives Medicare payment, subject to CMS rules and the approved enrollment relationship.

Question 19

Is the clinician still independently enrolled?

Accepted Answer

Yes. Reassignment does not replace the clinician’s individual enrollment.

Question 20

Can an employee reassign benefits?

Accepted Answer

Employment may support a valid practice relationship, but the reassignment still must be completed and approved through the CMS enrollment process.

Question 21

Can an independent contractor reassign benefits?

Accepted Answer

Some contractual arrangements may qualify, but do not assume contractor status alone is sufficient. Confirm the arrangement and CMS requirements in PECOS or with the MAC.

Question 22

What happens if the clinician leaves the practice?

Accepted Answer

The clinician and organization should promptly update or terminate the reassignment and locations in PECOS as applicable. The individual NPI remains with the clinician.

Question 23

Can the clinician treat patients while Medicare enrollment is pending?

Accepted Answer

Clinical practice permission and Medicare payment are different questions. Verify state licensure and supervision separately, and do not assume Medicare will pay claims before the approved effective date and reassignment are confirmed.

Question 24

Can Medicare claims be billed retroactively?

Accepted Answer

Limited retrospective billing may be permitted when all regulatory conditions are met, but it is not automatic. Confirm the individual and reassignment dates in PECOS and the MAC approval information before submitting claims.

Question 25

What determines the effective date?

Accepted Answer

For these suppliers, the billing-privilege date is generally the later of an enrollment filing date that is subsequently approved or the date services first began at the enrolled location, subject to current CMS rules. Use the dates Medicare actually approves.

Question 26

How long does enrollment take?

Accepted Answer

Processing varies with completeness, verification, workload, and development requests. Use the status tools and respond quickly; do not schedule billing around an unofficial estimate.

Question 27

Does my clinic need its own Medicare enrollment?

Accepted Answer

A practice that bills and receives Medicare payment generally needs the appropriate organization enrollment. This wizard assumes the Texas outpatient therapy practice is already enrolled.

Question 28

What if my practice is already enrolled?

Accepted Answer

The new clinician still needs an individual enrollment and an approved connection or reassignment to the correct organization and location.

Question 29

Can PT and OT bill through the same organization?

Accepted Answer

An eligible enrolled organization may include both disciplines when each clinician, specialty, location, reassignment, and claim is correctly enrolled and configured.

Question 30

Can a mobile outpatient practice enroll an OT?

Accepted Answer

A mobile model is not automatically disqualifying, but enrollment, service-location, practice, and therapy rules must fit the actual arrangement. Confirm the location setup with PECOS and Novitas before billing.

Question 31

Can the clinician work at more than one location?

Accepted Answer

Potentially, but every relevant practice location and reassignment must be accurately reported and approved as required. Do not bill a location that is not correctly reflected in enrollment.
