Where does M48.52 sit in the tabular list?

Diseases of the musculoskeletal system and connective tissue (M00-M99), in the block Spondylopathies (M45-M49).

What cannot be coded together with M48.52?

M48.52 — Collapsed vertebra, not elsewhere classified, cervical region

Non-billable headerICD-10-CM

M48.52 is a non-billable header ICD-10-CM code for collapsed vertebra, not elsewhere classified, cervical region. 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 subcategory M48.5:

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 M48.52

These are not written on M48.52, but they bind it: a note on a category applies to every code beneath it. Billing M48.52 with anything listed here is a denial.

Written on M48.5 — Collapsed vertebra, not elsewhere classified

current injury - see Injury of spine, by body region
fatigue fracture of vertebra (M48.4)
pathological fracture of vertebra due to neoplasm (M84.58)

pathological fracture of vertebra due to osteoporosis (M80.-)
pathological fracture NOS (M84.4-)
stress fracture of vertebra (M48.4-)

Other codes that can never be billed with M48.52

These codes carry an Excludes1 note pointing at M48.52. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading M48.52 alone.

Risk adjustment

M48.52 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 history

M48.52 has not changed since FY2024 — no addition, revision or deletion across the three most recent ICD-10-CM releases.
