S52.225D Nondisplaced transverse fracture of shaft of left ulna, subsequent encounter for closed fracture with routine healing

ICD-10-CM S52.225D: Nondisplaced transverse fracture of shaft of left ulna, subsequent encounter for closed fracture with routine healing

ICD-10-CM code S52.225D represents a subsequent encounter for a closed, nondisplaced transverse fracture of the shaft of the left ulna with routine healing. The code belongs to a broader family of left ulnar shaft fracture codes that distinguish between initial encounters, open fractures, and various healing phases. The supplied sources establish the code definition and related variations, alongside clinical literature discussing fracture risks and imaging. 3 1 2

Plain-language overview

Code S52.225D identifies a subsequent encounter for a closed, nondisplaced transverse fracture of the shaft of the left ulna with routine healing. This specific code description is explicitly documented in the provided coding reference. 3

What this code represents

The code S52.225D falls under the base category S52.225, which covers nondisplaced transverse fractures of the shaft of the left ulna. The provided reference lists multiple variations under this category that differentiate between initial encounters, open fracture types, and subsequent healing statuses. 3

Coding details

Within the S52.225 category, S52.225D is specifically designated for a subsequent encounter for a closed fracture with routine healing. The reference also lists separate subsequent encounter codes for delayed healing, nonunion, and malunion. 3

The provided coding reference distinguishes S52.225D from S52.225A, which is used for the initial encounter for a closed fracture. It is also distinct from S52.225E, which represents a subsequent encounter for an open type I or II fracture with routine healing. 3

Documentation considerations

The supplied coding reference explicitly defines S52.225D as a subsequent encounter for a closed fracture with routine healing. The provided sources do not explicitly outline the specific clinical documentation elements needed to support the use of this code. 3

Clinical context

One source establishes that any new fracture in an adult aged 50 years or older signifies an imminent elevated risk for subsequent fractures. This risk is noted to be particularly high in the year following the initial fracture. 1

A clinical source notes that computed tomography is useful for detecting occult fractures, documenting fracture extent, and determining subluxation, luxation, and malrotation of the radius and ulna. The provided sources do not explicitly link these imaging details to the S52.225D code. 2

What the sources add

The coding reference provides the specific code description and a list of related encounter and healing variations for left ulnar shaft fractures. In contrast, the clinical sources provide general information regarding subsequent fracture risks in older adults and imaging for ulnar injuries, without addressing coding rules. 3 1 2

Coverage and utilization context

The supplied coding reference defines the code S52.225D but does not contain statements regarding payer-specific coverage guidelines, reimbursement rates, or the principle that a diagnosis code does not guarantee coverage. 3
