How the Single-level CCS Works

Single-level CCS is most useful for ranking of diagnoses and procedures and for direct integration into risk adjustment and other software. This Single-level CCS lassifies all diagnoses and procedures into unique groups, has a total of 285 mutually exclusive categories.

Now look for some Example of ‘Single-level  CCS’

CCS Category     CCS Category Desc
1        Tuberculosis
2        Septicemia (except in labor)
3        Bacterial infection; unspecified site
4        Mycoses
5        HIV infection
6        Hepatitis
7        Viral infection
8        Other infections; including parasitic
9        Sexually transmitted infections (not HIV or hepatitis)
10        Immunizations and screening for infectious disease

Now try to understand how the ICD-9 Rolled in each of the CCS Category:
