Stefanie Mathis is listed in NPPES under Speech-Language Pathologist.
NPI assigned on August 26, 2014; this date does not establish years in practice.

What Public CMS Data Show

These CMS figures cover limited populations and published records; they are not quality ratings or medical advice.

Speech-Language Pathologist: NPPES taxonomy is a reported classification, not proof of board certification.

NPI first issued

2014

The year this clinician's National Provider Identifier (NPI) was issued. An NPI is a unique 10-digit ID that US health care providers use for billing.

What this does not show

NPIs have been issued only since 2005, so this year is not necessarily when the clinician started practicing.

Source: CMS NPPES NPI Registry.

Medicare assignment not listed

CMS data do not show whether this clinician accepts Medicare assignment. This does not mean they do not accept Medicare. Ask the office.

Medicare assignment applies to Original Medicare. It does not tell you whether the clinician is in a Medicare Advantage plan's network, accepts other insurance, or is taking new patients.

Source: CMS Doctors and Clinicians; Medicare.gov, “Does your provider accept Medicare as full payment?”

Guide: What Medicare assignment means

No telehealth indicator

CMS shows this indicator only when recent Medicare claims include telehealth services. The clinician may still offer telehealth; ask the office.
