A condition where the parathyroid glands produce too much hormone, affecting calcium and bone health.
For the 100% post-surgery rating, medical records documenting that surgery was performed and the date you were discharged afterward are the core evidence needed.
For the 60% rating, lab reports and imaging are central. Records showing a total calcium level above 12 mg/dL or an ionized calcium level above 5.6 mg/dL directly support this level. So do records showing a creatinine clearance below 60 mL/min, a bone mineral density scan with a T-score below 2.5 SD at any measured site, or documentation of a previous fragility fracture. Dates of these results matter because they can also establish when pharmacologic treatment began, which affects how long the 60% evaluation continues.
For the 10% rating, treatment records showing ongoing or continuous medication use are important, along with physician notes or VA examination findings that document symptoms such as fatigue, nausea, anorexia, or constipation after surgery or during non-surgical management. Your own statements describing how these symptoms affect your daily life and work can support what the medical records show.
For any residual conditions after treatment, such as kidney stones, reduced kidney function, fractures, vision problems, or cardiovascular complications, records specific to those conditions under their own diagnostic codes will be relevant.
Conditions that are often caused or made worse by this one. If you have any of these, they may be claimable as secondary service connection.
