Questions About M48.54XGOverview

Is M48.54XG a billable code?

Yes. This is a billable ICD-10-CM code, specific enough to report collapsed vertebra, not elsewhere classified, thoracic region, subsequent encounter for fracture with delayed healing on HIPAA-covered claims from October 1, 2026 through September 30, 2027.

What does the 7th character G in M48.54XG mean?

The final character G reports a subsequent encounter where the collapsed vertebra, not elsewhere classified, thoracic region is healing more slowly than expected. In this category the CMS Tabular List defines G as "subsequent encounter for fracture with delayed healing".

What MS-DRG does M48.54XG group to?

When collapsed vertebra, not elsewhere classified, thoracic region, subsequent encounter for fracture with delayed healing is the principal diagnosis on an inpatient stay, it groups to MS-DRG 559, 561, 560, with relative weights from 0.8258 to 1.8087 depending on complications. Higher weights mean higher Medicare reimbursement.

Can M48.54XG be reported with M48.4?

Not as a rule. The Excludes1 note at M48.5, which applies to M48.54XG, lists "fatigue fracture of vertebra (M48.4)". An Excludes1 note means the excluded code is never reported together with this one; the only exception is when the two conditions are unrelated to each other (Official Guidelines, Section I.A.12.a).

What is the ICD-9 equivalent of M48.54XG?

Under the General Equivalence Mappings, collapsed vertebra, not elsewhere classified, thoracic region, subsequent encounter for fracture with delayed healing converts to ICD-9-CM V54.27 (aftrcare path fx vertebr). The mapping is approximate, so confirm the match fits the documentation.
