Diagnostic Related Groups - MS-DRG Mapping
The ICD-10 code R41.2 is grouped in the following groups for version MS-DRG V39.0 What are Diagnostic Related Groups?
The Diagnostic Related Groups (DRGs) are a patient classification scheme which provides a means of relating the type of patients a hospital treats. The DRGs divides all possible principal diagnoses into mutually exclusive principal diagnosis areas referred to as Major Diagnostic Categories (MDC). applicable from 10/01/2021 through 09/30/2022.
| MS-DRG | MS-DRG Title | MCD | Relative Weight |
|---|---|---|---|
| 947 | SIGNS AND SYMPTOMS WITH MCC | 23 | 1.1901 |
| 948 | SIGNS AND SYMPTOMS WITHOUT MCC | 23 | 0.7856 |
The relative weight of a diagnostic related group determines the reimbursement rate based on the severity of a patient's illness and the associated cost of care during hospitalization.

Information for Patients
Memory
Every day, you have different experiences and you learn new things. Your brain cannot store all of that information, so it has to decide what is worth remembering. Memory is the process of storing and then remembering this information. There are different types of memory. Short-term memory stores information for a few seconds or minutes. Long-term memory stores it for a longer period of time.
Memory doesn't always work perfectly. As you grow older, it may take longer to remember things.
It's normal to forget things once in a while. We've all forgotten a name, where we put our keys, or if we locked the front door. If you are an older adult who forget things more often than others your age, you may have mild cognitive impairment. Forgetting how to use your phone or find your way home may be signs of a more serious problem, such as
- Alzheimer's disease
- Other types of dementia
- Stroke
- Depression
- Head injuries
- Blood clots or tumors in the brain
- Kidney, liver, or thyroid problems
- Reactions to certain medicines
If you're worried about your forgetfulness, see your health care provider.
