7th characters

7th characters for M80 defined here

The appropriate 7th character is to be added to each code from category M80:

7th characters for M80
7thMeaning (NCHS)
Ainitial encounter for fracture
Dsubsequent encounter for fracture with routine healing
Gsubsequent encounter for fracture with delayed healing
Ksubsequent encounter for fracture with nonunion
Psubsequent encounter for fracture with malunion
Ssequela

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.
