One or More Sessions: Global Surgery Period
The intent of the phrase 'one or more sessions' as used in the descriptor of a CPT code is to include all sessions in a complete defined treatment period. The defined treatment period is determined by the physician performing the service and varies with respect to the individual patient, the diagnosis and the location of treatment. For Medicare purposes, this means the defined global surgery period.
This phrase appears in descriptors for the following surgical CPT procedure codes performed on the eye and ocular adnexa:
| CPT Codes |
| 65855 |
66761 |
66762 |
67101 |
67105 |
67141 |
| 67145 |
67208 |
67210 |
67218 |
67227 |
67228 |
These codes should be reported once for the defined global surgery period to include all sessions during that period. For example, when laser photocoagulation of diabetic retinopathy requires four sessions, CPT code 67228 should be reported once. This includes the surgery and appropriate follow-up, post-operative management, over the ensuing 90-day global surgery period.
If a new or different condition appears within the global period, use an appropriate modifier to indicate the treatment is not part of the original series. If repeat treatment is necessary after the global surgery period because of disease progression, a new treatment or series of treatments should be reported using the appropriate code. The repeat treatment represents a new defined treatment period.
