Compare key differences between these codes to ensure accurate selection

CodeDescriptionWhen to UseKey Documentation
M76.6Achilles tendinitisUse when clinical findings confirm Achilles tendon inflammation without rupture.
  • Pain localized 2-6cm above calcaneal insertion
  • Positive arc sign
  • Inability to perform single-leg heel raise
M65.3Rotator cuff tendinitisUse when clinical examination confirms rotator cuff inflammation.
  • Painful arc (70-120° abduction)
  • Weakness in Hawkins-Kennedy test
  • Tenderness over greater tuberosity

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 Achilles tendinitis

Essential facts and insights about Tendinitis

The ICD-10 code for Achilles tendinitis is M76.6, indicating inflammation of the Achilles tendon.

Primary ICD-10-CM Codes for tendinitis

Achilles tendinitis
Non-billable Code

Decision Criteria

clinical Criteria

  • Presence of localized pain and positive arc sign

coding Criteria

  • Specify laterality and confirm absence of rupture

Applicable To

  • Achilles tendinitis

Excludes

Clinical Validation Requirements

  • Pain localized 2-6cm above calcaneal insertion
  • Positive arc sign
  • Inability to perform single-leg heel raise

Code-Specific Risks

  • Confusing with Achilles bursitis
  • Using unspecified codes

Coding Notes

  • Ensure laterality is specified to avoid unspecified coding.

Ancillary Codes

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

Presence of right shoulder joint implant

Z96.611
Use when there is a shoulder joint implant affecting mobility.

Acquired absence of limb affecting mobility

Z89.4
Use when limb absence affects treatment or mobility.

Differential Codes

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

Spontaneous rupture of other tendons

M66.8
Use if imaging confirms tendon rupture.

Rotator cuff syndrome

M75.1
Use if imaging shows degenerative changes.

Documentation & Coding Risks

Avoid these common documentation and coding issues when documenting Tendinitis to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code M76.6.

Impact

Clinical: May lead to incorrect treatment., Regulatory: Non-compliance with documentation standards., Financial: Potential for claim denials.

Mitigation Strategy

Always specify the tendon in clinical notes., Use detailed physical exam findings.

Impact

Reimbursement: May lead to claim denials or reduced payment., Compliance: Non-compliance with coding guidelines., Data Quality: Decreases accuracy of health records.

Mitigation Strategy

Always specify the affected tendon and laterality.

Impact

Using unspecified codes can trigger audits.

Mitigation Strategy

Ensure documentation includes specific details to support precise coding.

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.

Frequently Asked Questions

Common questions about ICD-10 coding for Tendinitis, with expert answers to help guide accurate code selection and documentation.

Documentation Templates for Tendinitis

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

Orthopedic evaluation of shoulder pain

Specialty: Orthopedics

Required Elements

  • Subjective: Patient's description of pain
  • Objective: Physical exam findings
  • Assessment: Diagnosis with laterality
  • Plan: Treatment plan

Example Documentation

Subjective: 55M reports worsening R shoulder pain when throwing. Rates 6/10 on VAS. Objective: ROM: R shoulder abduction 0-100° (pain 70-100°), Strength: 4/5 supraspinatus, Special Tests: (+) Hawkins, (-) Apprehension. Assessment: M65.211 - Right rotator cuff tendinitis, acute. Plan: Ultrasound-guided corticosteroid injection, home exercise program for scapular stabilization.

Examples: Poor vs. Good Documentation

Poor Documentation Example
Shoulder pain, treat with PT.
Good Documentation Example
Right shoulder pain exacerbated by overhead activity. Tenderness over supraspinatus insertion, painful arc (70-120°), Neer test positive. MRI shows tendon thickening without tear.
Explanation
The good example provides specific clinical findings and imaging results, supporting a precise diagnosis.
