Credentials and Medicare
| Licence | State | Specialty |
|---|---|---|
| DX2881 | MD | Renal Nutrition Registered Dietitian primary |
This provider holds licence DX2881 issued in MD. A licence number in NPPES reflects what was filed at registration — it does not confirm the licence is still active today.
This NPI does not appear in the PECOS Medicare enrolment file. Providers who do not bill Medicare — or who bill only through a group's enrolment — will not appear here. It is not a sign of any problem with the registration.
What Nutrition, Renal covers
An individual who is a Board Certified Specialist in Renal Nutrition and works directly with adult and/or pediatric patients with acute kidney injury, chronic kidney disease (CKD) stages 1-5, or receiving renal replacement therapies (dialysis/transplant) in a variety of settings, OR works indirectly in management, education, or research practice linked specifically to renal nutrition. The specialist in renal/nephrology nutrition is responsible for nutrition assessment, diagnosis, intervention, monitoring, and evaluation. NUCC Health Care Provider Taxonomy, code 133VN1005X
The taxonomy records how the provider classifies their own practice. It does not confirm which conditions they currently treat, whether they are accepting new patients, or which insurance they take — call the office for that.
Full NPPES record
An NPI-1 identifies a single person. It stays with the clinician for life, even if they move practice or change state, which is why the address on file can lag behind where they actually work today.

Number check
How the check works, step by step
Every NPI carries a Luhn check digit — the same scheme used on credit cards. CMS prefixes the number with 80840 before computing it, which marks it as a US health identifier.
| Digit | 8 | 0 | 8 | 4 | 0 | 1 | 4 | 7 | 7 | 1 | 9 | 4 | 0 | 5 |
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| Doubled? | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 |
| Value | 8 | 0 | 8 | 8 | 0 | 2 | 4 | 5 | 7 | 2 | 9 | 8 | 0 | 1 |
Sum = 62 · next multiple of 10 = 70 · check digit = 8 · actual last digit = 8
A valid check digit only means the number is well-formed. It does not mean the provider is licensed, active, or in good standing — those are separate questions answered by the sections above.
