Combination coding is a single code that fully describes the conditions and manifestation (Buck, Saunders, 2022). Multiple coding is when it takes more than one code to describe the conditions and manifestations. An example of combination coding is E11.321. This the code for Type 2 diabetes mellitus with mild nonproliferative diabetic retinopathy with macular edema (AAPC, 2022). This diagnosis was previously represented by 3 different codes with ICD- 9 (Outsource Strategies, 2018). An example of multiple codes would be N39.0, B96.20 for Urinary tract infection due to Escherichia coil (E. coli) (Buck, Saunders, 2022).
