MARK JOHANSEN, MD appears in the CMS NPPES registry as a Spinal Cord Injury Medicine Physician provider holding MD credentials at 3425 S CLARKSON ST, ENGLEWOOD, CO, 80113, with a listed phone of (303) 789-8220. NPI 1720066707 was issued on 01/09/2006. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what JOHANSEN 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 21 prescription claims written by this provider, covering N/A Medicare beneficiaries and totaling roughly $306 in drug spend. 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.

Spinal Cord Injury Medicine Physician is a narrow specialty nationwide, with 261 enrolled providers across 36 states and an average of 705 Part D claims per prescriber, so the context for interpreting these metrics differs meaningfully from a primary-care baseline. Important: PlainDoctor is a directory of publicly available government data, not medical advice, a malpractice database, or a quality rating. Inclusion here does not imply a recommendation, and absence of complaints or sanctions on this page does not mean none exist — always verify credentials through the NPPES NPI Registry, your state medical board, and the ABMS or AOA before making healthcare decisions.
