This reference uses VA rating codes. For a code from a medical record, check ICD-10-CM and the service date. A clinical code alone does not establish a VA rating or a matching VA diagnostic code.
Hyperparathyroidism
Endocrine · 38 CFR § 4.119
Diagnostic Code 7904 is the VASRD entry for Hyperparathyroidism. VA applies the controlling criteria, shared formulas, and special instructions shown in 38 CFR Part 4. VMC presents this material for education and reference; it does not determine a Veteran's diagnosis, service connection, or evaluation.

Source-verified VASRD criteria
How VA rates this diagnostic code
These percentages summarize the regulatory criteria already mapped to this diagnostic code. They do not predict a Veteran's individual evaluation or establish service connection.
For six months from date of discharge following surgery
Hypercalcemia (indicated by at least one of the following: Total Ca greater than 12 mg/dL (3-3.5 mmol/L), Ionized Ca greater than 5.6 mg/dL (2-2.5 mmol/L), creatinine clearance less than 60 mL/min, bone mineral density T-score less than 2.5 SD (below mean) at any site or previous fragility fracture)
Symptoms such as fatigue, anorexia, nausea, or constipation that occur despite surgery; or in individuals who are not candidates for surgery but require continuous medication for control
Asymptomatic
Regulatory notes
- Note (1): After six months, rate on residuals under the appropriate diagnostic code(s) within the appropriate body system(s) based on a VA examination.
- Note (2): Where surgical intervention is indicated, this evaluation shall continue until the day of surgery, at which time the provisions pertaining to a 100-percent evaluation shall apply.
- Note (3): Where surgical intervention is not indicated, this evaluation shall continue for six months after pharmacologic treatment begins. After six months, rate on residuals under the appropriate diagnostic code(s) within the appropriate body system(s) based on a VA examination.
- Note (4): Following surgery or other treatment, evaluate chronic residuals, such as nephrolithiasis (kidney stones), decreased renal function, fractures, vision problems, and cardiovascular complications, under the appropriate diagnostic codes.

VA maintains some examination forms that are not available for public use. VMC does not infer a one-code-to-one-DBQ relationship.
Evidence information
When reviewing the criteria, useful evidence categories can include diagnosis and treatment records, objective testing identified by the schedule, documented frequency/duration/severity when the criteria use those concepts, and functional effects described in medical or lay evidence. The relevant evidence depends on the actual claim and medical facts.
VMC does not diagnose conditions, guarantee a percentage, or advise anyone to exaggerate symptoms.
