7th characters
7th characters for S12 defined here
The appropriate 7th character is to be added to all codes from subcategories S12.0-S12.6
| 7th | Meaning (NCHS) |
|---|---|
| A | initial encounter for closed fracture |
| B | initial encounter for open fracture |
| D | subsequent encounter for fracture with routine healing |
| G | subsequent encounter for fracture with delayed healing |
| K | subsequent encounter for fracture with nonunion |
| S | sequela |
7th characters for S12.8 defined at S12.8
The appropriate 7th character is to be added to code S12.8
| 7th | Meaning (NCHS) |
|---|---|
| A | initial encounter |
| D | subsequent encounter |
| S | sequela |
7th characters for S12.9 defined at S12.9
The appropriate 7th character is to be added to code S12.9
| 7th | Meaning (NCHS) |
|---|---|
| A | initial encounter |
| D | subsequent encounter |
| S | sequela |
A code that takes a 7th character is invalid without it; the placeholder X fills a code shorter than 6 characters (Official Guidelines I.A.5). How 7th characters work.
