Intracranial and intraspinal abscess and granuloma in diseases classified elsewhere
In Inflammatory diseases of the central nervous system (G00-G09), chapter 6: Diseases of the Nervous System
- G07 is billable and valid on claims for FY 2027. If the record has more detail, check the other codes under G00-G09 below.
- As a secondary diagnosis it is an MCC (major complication), which can raise the MS-DRG payment. It doesn't count when the principal diagnosis is one of 72 closely related codes.
- Doesn't count toward a Medicare Advantage risk score (no HCC in V28).
- AHRQ's Chronic Condition Indicator classes it as not chronic (an acute or short-term condition).
- Can't be the principal diagnosis: code the underlying condition first. (Manifestation list)

- DRG 024 Craniotomy with Major Device Implant or Acute Complex CNS Principal Diagnosis without MCC
- DRG 094 Bacterial and Tuberculous Infections of Nervous System with MCC
- DRG 095 Bacterial and Tuberculous Infections of Nervous System with CC
- DRG 096 Bacterial and Tuberculous Infections of Nervous System without CC/MCC
- DRG 791 Prematurity with Major Problems

About the condition
Plain-language background from MedlinePlus (National Library of Medicine), not coding guidance.
Abscess
An abscess is a pocket of pus. You can get an abscess almost anywhere in your body. When an area of your body becomes infected, your body's immune system tries to fight the infection. White blood cells go to the infected area, collect within the damaged tissue, and cause inflammation. During this process, pus forms. Pus is a mixture of living and dead white blood cells, germs, and dead tissue.

Your brain is the control center of your body. It controls your thoughts, memory, speech, and movement. It regulates the function of many organs. It's part of your nervous system, which also includes your spinal cord and peripheral nerves. The nervous system sends signals between your brain and the rest of the body. Your nerves take in information from your senses and send it to the brain to be processed. Your brain and nerves also communicate to help you move and to control your body's functions.
