IHA releases a P4P Manual for each measurement year. The manual includes technical measure specifications along with data collection and reporting guidelines. A final measure set, audit manual and data submission file layouts are also released for each measurement year.
P4P follows NCQA standards for retiring and deleting obsolete measure specification codes. Codes that have been deleted from the standardized code sets (e.g., CPT, ICD-9, HCPCS) are removed from P4P measure specifications after the look-back period plus one additional year has been exhausted. This is explained in the General Guidelines of the P4P Manual, in a section titled Retiring Codes.
The document below includes codes that will be deleted from P4P over the next few years. There are three tabs that indicate for which P4P Measurement Year the codes are scheduled to be deleted.
Because this list is generated at a point in time, it is subject to change. For example, if additional codes are removed from the standardized code sets in 2012, they may wind up on the 2014 list in the future (provided the look-back period for the measure plus one additional year is exhausted by 2014). In addition, if tables are reordered or deleted, then the table names in this document may become inaccurate for the other years.
IHA conducts a call for public comment prior to finalizing measures and specifications. The call for public comments is applicable to the following measurement year as well as modifications to the current measurement year. The public comment period is typically in September and October and the final P4P Manuals are released in mid-November.
In spite of a thorough validation and quality assurance process, it is possible for discrepancies to be found in the results in the P4P Preliminary Reports. Therefore, there is a formal appeals process for both physician organizations (POs) and health plans to appeal for changes. The appeals process occurs after the release of PO preliminary reports, which usually occurs in June of the reporting year.
