S89.149S

S89.149S — Salter-Harris Type IV physeal fracture of lower end of unspecified tibia, sequela

Billable / specific codeICD-10-CMPOA exempt

S89.149S is a billable, specific ICD-10-CM code for salter-harris type iv physeal fracture of lower end of unspecified tibia, sequela. It is valid for submission on a claim.

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

Excludes1 inherited from the categories above S89.149S

These are not written on S89.149S, but they bind it: a note on a category applies to every code beneath it. Billing S89.149S with anything listed here is a denial.

Written on S89.14 — Salter-Harris Type IV physeal fracture of lower end of tibia

fracture of medial malleolus (adult) (S82.5-)

Excludes2 inherited from the categories above S89.149S

Also inherited, and the opposite of Excludes1: these conditions are not part of S89.149S, but a patient can have both, so you may code both.

Written on S89 — Other and unspecified injuries of lower leg

other and unspecified injuries of ankle and foot (S99.-)

Risk adjustment

S89.149S 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.

Medicare coverage

S89.149S is named in 1 Medicare coverage policy — 1 listing it as supporting medical necessity. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.
