Implied documentation requirements: documentation that the procedure is a 'last resort' for terminal cancer pain (i.e., record of terminal cancer diagnosis and that other appropriate pain treatments have been tried and failed), and that care is provided in the context of palliative/terminal care (ICD-10 Z51.5).
Policy notes and cited consensus/guidelines emphasize need for strict inclusion criteria, multidisciplinary evaluation, documented refractoriness to standard therapies, and proper consent procedures (as described in background and references), although these are not enumerated as specific required documentation items in the CPB.
