No explicit 'Documentation Requirements' section is provided in the CPB. However the policy repeatedly states coverage is contingent on meeting unspecified 'selection criteria' (e.g., CPT and HCPCS codes 'covered if selection criteria are met') — documentation should therefore demonstrate that the member meets the selection criteria for coverage (diagnosis and medical necessity).
For incentive spirometers: documentation should include evidence of post-operative status and presence of neuromuscular or chest wall disease when claiming DME incentive spirometer coverage (policy: 'Incentive spirometers as durable medical equipment (DME) for post-operative use for members with neuromuscular or chest wall diseases;').
