Final answer:
Under HIPAA regulations, you can generally disclose the exact age of a patient unless they are over 89 years old, at which point only the age range of '90 or older' can be disclosed.
Step-by-step explanation:
The answer to whether you can give the exact age of a patient under HIPAA regulations depends on specific age thresholds set by the HIPAA Privacy Rule. Generally, for patients who are under 89 years of age, their exact age can be disclosed as part of a limited data set. However, for patients above the age of 89, HIPAA requires that the age is not disclosed in exact terms and instead is only indicated as 'age 90 or older.' This is part of the standard to ensure additional privacy protections for individuals in this age group, who might be at enhanced risk of identification due to the smaller size of their population demographic.
