M65-M67Primary Range

Synovitis and tenosynovitis

This range includes primary codes for synovitis and related conditions, covering various types and locations of synovitis.

Soft tissue disorders related to use, overuse and pressure

This range includes codes for overuse-related synovitis, which are excluded from primary synovitis codes.

CodeDescriptionWhen to UseKey Documentation
M65.9Unspecified synovitis and tenosynovitisUse when synovitis is diagnosed but specific location is not documented.
  • Clinical diagnosis of synovitis without specific location
M67.3Transient synovitisUse for self-limiting synovitis in children, often affecting the hip.
  • Diagnosis of transient synovitis, typically in children, with normal ESR

Clinical Decision Support

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

Key Information: ICD-10 code for synovitis

Essential facts and insights about Synovitis

The ICD-10 code for unspecified synovitis is M65.9, used when the specific location is not documented.

Primary ICD-10-CM Codes for synovitis

Unspecified synovitis and tenosynovitis
Non-billable Code

Decision Criteria

documentation Criteria

  • Location of synovitis is not specified

Applicable To

  • General synovitis without specific location

Excludes

  • Overuse-related synovitis (M70.-)

Clinical Validation Requirements

  • Clinical diagnosis of synovitis without specific location

Code-Specific Risks

  • Risk of under-documentation leading to unspecified coding

Coding Notes

  • Ensure documentation specifies the location to avoid unspecified coding.

Differential Codes

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

Bursitis

M71.2
Bursitis involves inflammation of the bursa, not the synovium.

Other synovitis and tenosynovitis

M65.8
Chronic or non-transient synovitis should be coded here.

Documentation & Coding Risks

Avoid these common documentation and coding issues when documenting Synovitis to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code M65.9.

Impact

Clinical: May lead to incorrect treatment plans., Regulatory: Non-compliance with ICD-10 coding standards., Financial: Potential for denied claims due to lack of specificity.

Mitigation Strategy

Always include laterality in documentation, Use templates that prompt for laterality

Impact

Reimbursement: May lead to reduced reimbursement due to lack of specificity., Compliance: Non-compliance with coding guidelines for specificity., Data Quality: Decreases the quality of clinical data.

Mitigation Strategy

Always document and code the specific location of synovitis.

Impact

High risk of audits due to use of unspecified codes.

Mitigation Strategy

Ensure specific documentation of synovitis location and type.

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 Synovitis

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

Rheumatoid synovitis documentation

Specialty: Rheumatology

Required Elements

  • Patient history of rheumatoid arthritis
  • Specific joint affected
  • Imaging results
  • Lab results

Examples: Poor vs. Good Documentation

Poor Documentation Example
Patient has wrist pain.
Good Documentation Example
Patient presents with swelling and pain in the right wrist. Ultrasound shows synovial hypertrophy. CRP elevated.
Explanation
The good example provides specific details about the joint affected and supporting diagnostic evidence.
