CMSSource: CMS FY 2027 ICD-10-CM dataset · Effective Oct 1, 2026 – Sep 30, 2027

S82.245B is a billable ICD-10-CM diagnosis code for nondisplaced spiral fracture of shaft of left tibia, initial encounter for open fracture type I or II. The 7th character B means initial encounter for open fracture type I or II. It is valid on HIPAA claims for fiscal year 2027 (October 1, 2026 through September 30, 2027) and groups to MS-DRG 562 through 563, 963 through 965. As a secondary diagnosis, it counts as a major complication or comorbidity (MCC) and places an inpatient stay in the highest severity level of its MS-DRG family. It does not count, however, when the principal diagnosis is one of 575 closely related codes. In AHRQ's Clinical Classifications Software (CCSR), this diagnosis falls under Fracture of the lower limb (except hip), initial encounter.

Coding GuidelinesGuidance

The principles of multiple coding of injuries should be followed in coding fractures. Fractures of specified sites are coded individually by site, to the level of detail furnished by medical record content.

A fracture not indicated as open or closed should be coded to closed. A fracture not indicated whether displaced or not displaced should be coded to displaced.

Initial vs. Subsequent Encounter for Fractures

Traumatic fractures are coded using the appropriate 7th character for initial encounter (A, B, C) while the patient is receiving active treatment for the fracture. The appropriate 7th character for initial encounter should also be assigned for a patient who delayed seeking treatment for the fracture or nonunion.

Fractures are coded using the appropriate 7th character for subsequent care for encounters after the patient has completed active treatment of the fracture and is receiving routine care for the fracture during the healing or recovery phase.

Care for complications of surgical treatment for fracture repairs during the healing or recovery phase should be coded with the appropriate complication codes.

Care of complications of fractures, such as malunion and nonunion, should be reported with the appropriate 7th character for subsequent care with nonunion (K, M, N) or subsequent care with malunion (P, Q, R).

The open fracture designations in the assignment of the 7th character for fractures of the forearm, femur and lower leg, including ankle are based on the Gustilo open fracture classification. When the Gustilo classification type is not specified for an open fracture, the 7th character for open fracture type I or II should be assigned (B, E, H, M, Q).

Notes

General instructions on how these codes are used.

From S82 Fracture of lower leg, including ankle applies to 3,096 codes
  • A fracture not indicated as displaced or nondisplaced should be coded to displaced

Questions About S82.245BOverview

Is S82.245B (Nondisplaced spiral fracture of shaft of left tibia) a billable code?

Yes. This is a billable ICD-10-CM code, specific enough to report nondisplaced spiral fracture of shaft of left tibia, initial encounter for open fracture type I or II on HIPAA-covered claims from October 1, 2026 through September 30, 2027.

What does the 7th character B in S82.245B mean?

The final character B means initial encounter for open fracture type I or II, in this case for the nondisplaced spiral fracture of shaft of left tibia. It comes from the 7th character list in the CMS Tabular List for this category.

What MS-DRG does S82.245B group to?

When nondisplaced spiral fracture of shaft of left tibia, initial encounter for open fracture type I or II is the principal diagnosis on an inpatient stay, it groups to MS-DRG 563, 964, 965, 562, 963, with relative weights from 0.8982 to 2.6361 depending on complications. Higher weights mean higher Medicare reimbursement.

Is S82.245B a CC or MCC?

CMS lists S82.245B as an MCC (major complication or comorbidity) for FY 2027. Reported as a secondary diagnosis, it places the inpatient stay in the highest-weighted DRG of its severity family. It does not count when the principal diagnosis is one of the 575 closely related codes in its exclusion list.

Can S82.245B be reported with a code from S88?

Not as a rule. The Excludes1 note at S82, which applies to S82.245B, lists "traumatic amputation of lower leg (S88.-)". 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).
