Non-billable headerICD-10-CM

S89.13 is a non-billable header ICD-10-CM code for salter-harris type iii physeal fracture of lower end of tibia. It cannot be billed on its own: choose one of the more specific child codes below. This code also requires a 7th character before it is complete.

This code requires a 7th character

The appropriate 7th character is to be added to each code from subcategories S89.0, S89.1, S89.2, and S89.3

A: initial encounter for closed fracture
D: subsequent encounter for fracture with routine healing
G: subsequent encounter for fracture with delayed healing
K: subsequent encounter for fracture with nonunion
P: subsequent encounter for fracture with malunion
S: sequela

Excludes1 — never code together

These conditions cannot occur together. Billing both on the same encounter is a denial.

Other codes that can never be billed with S89.13

These codes carry an Excludes1 note pointing at S89.13. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading S89.13 alone.

Risk adjustment

S89.13 does not map to an HCC and does not risk-adjust under CMS-HCC V28. That is normal — most ICD-10 codes do not. It still needs to be coded correctly; it just will not move a RAF score.

Code to one of these instead S89.13
