diagnosis-Related Groups (DRG) a system of classification or grouping of patients according to medical diagnosis for purposes of paying hospitalization costs. In 1983, amendments to Social Security contained a prospective payment plan for most Medicare inpatient services in the United States. The payment plan was intended to control rising health care costs by paying a fixed amount per patient. The program of DRG reimbursement was based on the premise that similar medical diagnoses would generate similar costs for hospitalization. Therefore, all patients admitted for a surgical procedure such as hernia repair would be charged the same amount regardless of actual cost to the hospital. If a patient's hospital bill should total less than the amount paid by Medicare, the hospital is allowed to keep the difference. If, however, a patient's bill is more than that reimbursed by Medicare for a specific diagnosis, the hospital must absorb the difference in cost. See also appendix of Diagnosis-Related Groups.

a name given to a disease so that each veterinarian means the same syndrome as every other veterinarian. It is then possible to prescribe for and make a prognosis about any one case on the basis of the outcomes in a series of animals with the same diagnosis. A diagnosis may be the name of a disease with a specific etiology, or one which is only a description of the morphological identity of the disease, a pathoanatomical diagnosis, or be a syndrome which is a description of the total symptomatology, or a single clinical sign.

clinical diagnosis
diagnosis based on clinical signs and laboratory findings during life.
computer assisted diagnosis
a computer program identifies the diseases that fit the identified abnormalities best.
differential diagnosis
the determination of which one of several diseases may be producing the signs observed.
etiological diagnosis
identifies the specific cause of the disease.
pathoanatomical diagnosis
diagnosis to the point of identifying the system and organ involved and the nature of the lesion, but short of identifying the cause.
physical diagnosis
diagnosis based on information obtained by inspection, palpation, percussion and auscultation.
radiological diagnosis
a good radiological report does more than report findings. It interprets these findings if possible up to the point of making a pathoanatomical diagnosis (see above).
veterinary diagnosis
diagnosis performed by a veterinarian and based on information gleaned from a variety of sources, including (1) findings from a physical examination, (2) interview with the owner or custodian of the animal, (3) veterinary history of the patient and its cohorts and (4) paraclinical findings as reported by pertinent laboratory tests and radiological studies.

1. Term that indicates the disease (e.g. pulmonary tuberculosis) or the refractive error (e.g. compound myopic astigmatism) that a person has. 2. The art of determining a disease or visual anomaly based on the signs, symptoms and tests.

Patient discussion about diagnosis.

Q. How is the diagnosis of autism made? My friend has a child who is suspected to have autism. I wanted to find out more about making the diagnosis of autism.

A. Diagnosing autism is not an easy task, especially when there are several other conditions that might confuse the clinician with this disorder or spectrum of disorders. The child usually has several symptoms that suggest an autistic disorder, such as impaired social behavior. Several diagnostic instruments (tests) are available. Two are commonly used in autism research: the Autism Diagnostic Interview-Revised (ADI-R) is a semistructured parent interview, and the Autism Diagnostic Observation Schedule (ADOS) uses observation and interaction with the child. The Childhood Autism Rating Scale (CARS) is used widely in clinical environments to assess severity of autism based on observation of children.
A pediatrician commonly performs a preliminary investigation by taking developmental history and physically examining the child.. If warranted, diagnosis and evaluations are conducted with help from ASD specialists, observing and assessing cognitive, communication, family, and other factors

Q. Is the diagnosis correct? I have been diagnosed bipolar and was previously diagnosed with depression and ADHD how I know the diagnosis is correct this time?

A. a psychologist/psychiatrist should also have the possibility with a questionary to detect if you have bipolar disorder and/or adhd. i have both and live with it since i am a child. i had my first "out-of-control"-crisis with 29 years. in the meantime i am 46 (in two days) and i still live! i had also many times the wish to make suicide, but this is the worst solution. do you live alone? do you have a dog? do you have a job? what are your talents? what do you love to do in life? write it down and look what you could put on a focus. what are the things you do daily that allows you to stop thinking of all your trouble? write it down. to make a puzzle? play chess with your neighbor? to chat online? you only can collect what could help you in such cases to keep the bad thoughts you have away from yourself. there is always at least one good solution. i give you here some ideas. never give up! thank you
