*ICD10 does not have separate codes for hyperphosphatemia and hypophosphatemia

*The single criterion for coding this is P04 <=0.5

*The ~~parameters~~ for coding ~~hyperphosphatemia are any of the following 3 items: (This change~~ is ~~active as of Feb 12, 2018)~~

*Presence/absence of signs or symptoms are not part of the coding criterion, though they are:

**PO4 > 2.~~0 '''OR'''~~

**Any PO4 > 1.6 AND in the presence of signs or symptoms ~~believed to be due to hyperphosphatemia '''OR'''~~

**Any PO4 > 1.6 with active treatment for hyperphosphatemia

**Hyperphosphatemia is not ~~an acute clinical problem/issue~~

***It can be a long-term issue as it can lead to: metastatic calcification, hypocalcemia

*The parameters for coding hypophosphatemia are any of the ~~following 3 items: (This change is active as of Feb 12, 2018)~~

**PO4 < 0.3 '''OR'''

**Any PO4 < 1,~~0 AND in the presence of signs or symptoms believed to be due to hypophosphatemia '''OR'''~~

**Any PO4 < 1.0 with active treatment for hypophosphatemia

*Main signs and symptoms of hypophosphatemia are:

**neuromuscular - myopathy (weakness, increased CPK, respiratory failure, rhabdomyolysis), congestive cardiomyopathy

**hematologic - hemolysis, WBC dysfunction, platelet dysfunction

Line 19:

**bone - osteomalacia\Ricketts, bone pain

**cardiovascular - CHF

*Note that as of April 2025, there no longer is a code that includes hyperphosphatemia.
