State Policy Variation and Telehealth Use by Oncology Specialists Treating Medicaid Patients

Telehealth may improve access to specialized oncology care for Medicaid beneficiaries with hematological malignancies who face geographic and financial barriers. During the COVID-19 public health emergency, telehealth use expanded rapidly, yet state policies governing telehealth coverage/payment parity varied. Evidence is limited on how these policy differences influenced oncology telehealth use for Medicaid patients. We conducted a cross-sectional analysis of 2020-2021 multistate Medicaid claims. Adult and pediatric oncology specialists were identified based on board certification data. Telehealth video visits were measured monthly at the extensive margin, defined as the proportion of specialists providing any telehealth, and the intensive margin, defined as average monthly telehealth visits among telehealth providing specialists. States were categorized by private insurance telehealth policy environment: coverage and payment parity, coverage parity only, or no or unspecified parity. Telehealth use increased sharply across all states in early 2020, rising from less than 1% of specialists before the pandemic to peak levels by April 2020. Specialists practicing in coverage and payment parity states demonstrated higher and more sustained telehealth use through 2021 compared with those in coverage only or no parity states. By December 2021, 15.1% of adult specialists in coverage and payment parity states provided telehealth, compared with 8.1% in coverage-only states and 7.8% in no-parity states. Pediatric specialists showed similar patterns, though overall telehealth use remained lower. Specialists in parity states also maintained higher monthly telehealth visit volumes over time. State-level coverage and payment parity policies may have been associated with greater and sustained telehealth provision by oncology specialists treating Medicaid beneficiaries with hematologic malignancies. Maintaining supportive telehealth policies may be essential for promoting equitable access to specialized cancer care and reducing disparities among underserved populations. These findings inform future telehealth policy decisions nationally statewide.
