Antibiotic Resistance
Antibiotics are medicines that treat bacterial infections in humans and animals. They work by killing the bacteria or making it hard for the bacteria to grow and multiply. When used properly, antibiotics can save lives. But there is a growing problem of antibiotic resistance.

What MS-DRG does B95.62 group to?
On inpatient claims, methicillin resistant Staphylococcus aureus infection as the cause of diseases classified elsewhere maps to MS-DRG 867, 868, 869, with relative weights from 0.7297 to 2.0932 depending on complications. Higher weights mean higher Medicare reimbursement.
Can B95.62 be a principal diagnosis?

Report it as a secondary diagnosis.
What is the ICD-9 equivalent of B95.62?
Under the General Equivalence Mappings, methicillin resistant Staphylococcus aureus infection as the cause of diseases classified elsewhere converts to ICD-9-CM 041.12 (MRSA elsewhere/NOS). The mapping is approximate, so confirm the match fits the documentation.
Footnotes
[1] Not chronic - A diagnosis code that does not fit the criteria for chronic condition (duration, ongoing medical treatment, and limitations) is considered not chronic. Some codes designated as not chronic are acute conditions. Other diagnosis codes that indicate a possible chronic condition, but for which the duration of the illness is not specified in the code description (i.e., we do not know the condition has lasted 12 months or longer) also are considered not chronic.
