CodeDescriptionWhen to UseKey Documentation
M76.71Peroneal tendinitis, right legUse when documentation specifies right peroneal tendinitis confirmed by imaging.
  • Tenderness along the peroneal tendons behind the lateral malleolus
  • MRI or ultrasound confirmation of tendinosis
M76.72Peroneal tendinitis, left legUse when documentation specifies left peroneal tendinitis confirmed by imaging.
  • Tenderness along the peroneal tendons behind the lateral malleolus
  • MRI or ultrasound confirmation of tendinosis
M76.70Peroneal tendinitis, unspecified legUse when documentation does not specify laterality.
  • Generalized ankle pain without specified laterality

Clinical Decision Support

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

Other injury of muscle and tendon of peroneal group at lower leg level, right leg

S86.391
Use for acute traumatic tears, not chronic tendinitis.

Other injury of muscle and tendon of peroneal group at lower leg level, left leg

S86.392

Documentation & Coding Risks

Avoid these common documentation and coding issues when documenting Peroneal Tendonitis to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code M76.71.

Impact

Clinical: May lead to misdiagnosis or inappropriate treatment., Regulatory: Fails to meet documentation standards for specificity., Financial: Could result in denied claims or lower reimbursement.

Mitigation Strategy

Educate clinicians on documentation standards, Use templates that prompt for specific details

Impact

Reimbursement: Incorrect code may lead to denied claims., Compliance: Non-compliance with specificity requirements., Data Quality: Inaccurate data on tendonitis prevalence.

Mitigation Strategy

Ensure documentation specifies 'peroneal' to use M76.7x codes.

Impact

Reimbursement: Unspecified codes may result in lower reimbursement., Compliance: Fails to meet laterality documentation standards., Data Quality: Loss of specific clinical data on affected sides.

Mitigation Strategy

Code each side separately with M76.71 and M76.72.

Impact

Using M76.70 can lead to audit flags due to lack of specificity.

Mitigation Strategy

Ensure all documentation specifies laterality.

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.

Documentation Templates for Peroneal Tendonitis

Use these documentation templates to ensure complete and accurate documentation for Peroneal Tendonitis. These templates include all required elements for proper coding and billing.

Chronic peroneal tendinitis in a runner

Specialty: Orthopedics

Required Elements

  • Patient history including activity level
  • Physical exam findings
  • Imaging results
  • Specific tendon and laterality

Example Documentation

34yo female marathon runner reports 6-week history of progressive right lateral ankle pain worsening during toe-off phase. Denies trauma. Swelling posterior to lateral malleolus. Positive resisted eversion test. Ultrasound shows peroneus brevis tendinosis without tear. Assessment: Chronic peroneal tendinitis, right leg (M76.71).

Examples: Poor vs. Good Documentation

Poor Documentation Example
Lateral ankle pain, will order PT.
Good Documentation Example
Localized tenderness over peroneus brevis tendon (right). MRI shows tenosynovitis. Start eccentric strengthening PT protocol for M76.71.
Explanation
The good example specifies the tendon, laterality, and includes imaging confirmation, which supports accurate coding.
