M48.45XD — Fatigue fracture of vertebra, thoracolumbar region, subsequent encounter for fracture with routine healing
M48.45XD is a billable, specific ICD-10-CM code for fatigue fracture of vertebra, thoracolumbar region, subsequent encounter for fracture with routine healing. It is valid for submission on a claim.
7th character "D" — subsequent encounter for fracture with routine healing
The appropriate 7th character is to be added to each code from subcategory M48.4:
- A
- initial encounter for fracture
- D
- subsequent encounter for fracture with routine healing
- G
- subsequent encounter for fracture with delayed healing
- S
- sequela of fracture
Excludes1 inherited from the categories above M48.45XD
These are not written on M48.45XD, but they bind it: a note on a category applies to every code beneath it. Billing M48.45XD with anything listed here is a denial.
Written on M48.4 — Fatigue fracture of vertebra
Other codes that can never be billed with M48.45XD
These codes carry an Excludes1 note pointing at M48.45XD. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading M48.45XD alone.

Risk adjustment
M48.45XD 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
M48.45XD is named in 11 Medicare coverage policies — 4 listing it as supporting medical necessity, and 7 listing it as NOT covered. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.
