David Niekamp, D.C., NP-C appears in the CMS NPPES registry as a Chiropractor provider holding D.C., NP-C credentials at 3100 TIMMONS LN STE 330, Houston, TX, 77027, with a listed phone of (713) 790-1400. NPI 1114117132 was issued on 07/26/2007. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what Niekamp most recently submitted to CMS rather than a vetted directory listing, which is why patients should always confirm the practice is still at this location before scheduling.

Medicare Part D records for calendar year 2023 show 1,590 prescription claims written by this provider, covering 193 Medicare beneficiaries and totaling roughly $68K in drug spend, split 3% brand-name and 97% generic by claim count, with an opioid prescribing rate of 8.4%. These figures capture only Medicare Part D — commercial insurance, Medicaid, and cash-pay prescriptions are not included, and any drug-beneficiary cell under 11 is suppressed by CMS for patient privacy.

Chiropractor is a high-volume specialty nationwide, with 95,153 enrolled providers across 56 states and an average of 824 Part D claims per prescriber, so the context for interpreting these metrics differs meaningfully from a primary-care baseline.
