Code Description

ICD-10 M46.38 is a billable code used to indicate a diagnosis of infection of intervertebral disc (pyogenic), sacral and sacrococcygeal region.

Key Diagnostic Point:

M46.38 refers to a pyogenic infection of the intervertebral disc located in the sacral and sacrococcygeal region. This condition is characterized by the presence of bacteria that invade the disc space, leading to inflammation, pain, and potential neurological deficits. The infection can arise from hematogenous spread, direct extension from adjacent structures, or post-surgical complications. Clinically, patients may present with localized pain, fever, and neurological symptoms depending on the extent of the infection and any resultant spinal cord compression. Diagnosis typically involves imaging studies such as MRI, which can reveal disc space narrowing, edema, and abscess formation. Treatment often requires a combination of antibiotics and surgical intervention to debride infected tissue and relieve pressure on neural structures. The condition can be associated with other spondylopathies, including ankylosing spondylitis and spinal stenosis, which may complicate the clinical picture and management.

Code Complexity Analysis

Complexity Rating: High

High Complexity

Complexity Factors

  • Differentiating between pyogenic and non-pyogenic infections
  • Identifying the specific anatomical location of the infection
  • Understanding the relationship with other spinal conditions
  • Need for detailed imaging and clinical documentation

Audit Risk Factors

  • Inadequate documentation of infection type
  • Failure to specify the anatomical location
  • Lack of imaging reports to support diagnosis
  • Incorrect coding of associated conditions

Diagnostic & Documentation Impact

Enhanced Specificity

ICD-10 Improvements

The transition to ICD-10 has allowed for more specific coding of conditions like M46.38, improving the accuracy of data collection and reimbursement processes. It has also enhanced the ability to track epidemiological trends in spinal infections.

Frequently Asked Questions

What are the common causes of pyogenic discitis?

Common causes include hematogenous spread from distant infections, direct extension from adjacent infections, and post-surgical complications. Conditions such as diabetes and immunosuppression can increase the risk.
