CodeDescriptionWhen to UseKey Documentation
M25.571Pain in right ankle and joints of right footUse when pain is specifically localized to the sinus tarsi of the right foot and confirmed by clinical findings.
  • MRI showing synovitis or fibrosis
  • Positive dynamic impingement test
  • Relief after injection into sinus tarsi
M25.572Pain in left ankle and joints of left footUse when pain is specifically localized to the sinus tarsi of the left foot and confirmed by clinical findings.
  • MRI showing synovitis or fibrosis
  • Positive dynamic impingement test
  • Relief after injection into sinus tarsi
M25.579Pain in unspecified ankle and joints of unspecified footUse when pain is localized to the sinus tarsi but laterality is not specified.
  • MRI showing synovitis or fibrosis
  • Positive dynamic impingement test
  • Relief after injection into sinus tarsi

Clinical Decision Support

Always review the patient's clinical documentation thoroughly. When in doubt, choose the more specific code and ensure documentation supports it.

Decision Criteria

clinical Criteria

  • Pain localized to sinus tarsi with imaging confirmation

Applicable To

  • Pain localized to sinus tarsi of the right foot

Excludes

  • Generalized ankle pain without specific localization

Clinical Validation Requirements

  • MRI showing synovitis or fibrosis
  • Positive dynamic impingement test
  • Relief after injection into sinus tarsi

Code-Specific Risks

  • Risk of using unspecified code when laterality is documented

Coding Notes

  • Ensure documentation specifies laterality and location of pain.

Ancillary Codes

Additional codes that should be used in conjunction with the main diagnosis codes when applicable.

MRI of ankle without contrast

73721
Use to confirm synovitis or fibrosis in sinus tarsi.

Differential Codes

Alternative codes to consider when ruling out similar conditions to the primary diagnosis.

Peroneal tendinopathy

M76.5-
Pain and tenderness along peroneal tendons rather than sinus tarsi.

Documentation & Coding Risks

Avoid these common documentation and coding issues when documenting Sinus Tarsi Syndrome to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code M25.571.

Impact

Clinical: May lead to misdiagnosis or inappropriate treatment., Regulatory: Non-compliance with documentation standards., Financial: Potential claim denials due to lack of specificity.

Mitigation Strategy

Train staff on importance of detailed documentation, Use templates that prompt for specific details

Impact

Reimbursement: May lead to incorrect DRG assignment and reimbursement issues., Compliance: Non-compliance with coding guidelines for specificity., Data Quality: Reduces accuracy of clinical data and reporting.

Mitigation Strategy

Ensure laterality is documented and use M25.571 or M25.572 accordingly.

Impact

Failure to document laterality can lead to incorrect coding.

Mitigation Strategy

Implement mandatory fields in EHR for laterality documentation.

Documentation errors, coding pitfalls, and audit risks are interconnected aspects of medical coding and billing. Addressing all three areas helps ensure accurate coding, optimal reimbursement, and regulatory compliance.

Orthopedic evaluation of sinus tarsi syndrome

Specialty: Orthopedics

Required Elements

  • Specific location of pain
  • Imaging findings
  • Response to diagnostic tests

Example Documentation

**Subjective**: Pt reports pain localized to sinus tarsi, worsens with inversion. **Objective**: Tenderness at sinus tarsi, MRI shows synovitis. **Assessment**: Sinus tarsi syndrome (M25.571). **Plan**: Consider injection into sinus tarsi.

Examples: Poor vs. Good Documentation

Poor Documentation Example
Ankle pain.
Good Documentation Example
Pain localized to sinus tarsi with tenderness on palpation, MRI shows synovitis.
Explanation
The good example specifies the location and includes imaging findings, which are necessary for accurate coding.
