CodeDescriptionWhen to UseKey Documentation
M65.1Other infective (teno)synovitisUse when there is confirmed infection in the tendon sheath, supported by clinical signs and lab results.
  • Kanavel's signs
  • Purulent drainage
  • Elevated WBC or CRP
M65.8Other synovitis and tenosynovitisUse for non-infectious cases, particularly those associated with conditions like rheumatoid arthritis.
  • Absence of infection markers
  • History of autoimmune conditions

Clinical Decision Support

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

Documentation & Coding Risks

Avoid these common documentation and coding issues when documenting Flexor Tenosynovitis to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code M65.1.

Impact

Clinical: Misdiagnosis risk., Regulatory: Non-compliance with coding standards., Financial: Potential claim denials.

Mitigation Strategy

Ensure culture results are documented., Specify organism if known.

Impact

Reimbursement: Incorrect coding can lead to denied claims., Compliance: Non-compliance with coding guidelines., Data Quality: Inaccurate clinical data representation.

Mitigation Strategy

Use M65.1 with an organism code if infection is confirmed.

Impact

Using non-specific codes for confirmed infections.

Mitigation Strategy

Regular training on coding guidelines and documentation standards.

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 Flexor Tenosynovitis

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

Acute infectious flexor tenosynovitis

Specialty: Orthopedics

Required Elements

  • Kanavel's signs
  • Culture results
  • Operative findings

Example Documentation

Patient presents with acute swelling and pain in the right index finger. Kanavel's signs positive. Culture confirms MRSA. Incision and drainage performed.

Examples: Poor vs. Good Documentation

Poor Documentation Example
Patient has finger infection.
Good Documentation Example
Acute onset of right index finger fusiform swelling, tenderness along flexor sheath, pain on passive extension. Ultrasound confirms sheath effusion. Aspiration yields purulent fluid.
Explanation
The good example provides specific clinical signs and diagnostic findings, supporting the diagnosis and coding.
