Hello and thank you for your question. For CMS108v12/VTE-1 and CMS190v12/VTE-2 measures, ambulation alone is not a sufficient reason for not administering VTE prophylaxis. Reasons for no pharmacological and/or no mechanical VTE prophylaxis must be explicitly documented by the MD/APN/PA or pharmacist and linked with VTE prophylaxis. In order for ambulation to be considered as an acceptable reason, there needs to be explicit documentation, e.g., “patient out of bed and ambulating in halls – no VTE prophylaxis needed.” We hope this helps.
