Key Information: ICD-10 code for neck strain

Essential facts and insights about Neck Strain

The ICD-10 code for neck strain is S16.1XXA, applicable for initial encounters involving strain of muscle, fascia, and tendon at the neck level.

Primary ICD-10-CM Code for neck strain

Strain of muscle, fascia, and tendon at neck level, initial encounter
Billable Code

Decision Criteria

clinical Criteria

  • Presence of muscle tenderness and limited range of motion

documentation Criteria

  • Detailed mechanism of injury and specific muscle involvement

Applicable To

  • Acute neck strain
  • Cervical muscle strain

Excludes

  • Cervicalgia (M54.2)
  • Sprain of ligaments of cervical spine (S13.4XXA)

Clinical Validation Requirements

  • Localized muscle tenderness
  • Pain with active range of motion
  • Imaging showing muscle edema

Code-Specific Risks

  • Incorrectly coding non-traumatic neck pain as strain
  • Omitting mechanism of injury

Coding Notes

  • Ensure documentation specifies the exact muscle or tendon involved and the mechanism of injury.

Ancillary Codes

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

Fall on same level from slipping, tripping and stumbling, initial encounter

W01.XXXA
Use to describe the external cause of the neck strain.

Differential Codes

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

Sprain of ligaments of cervical spine, initial encounter

S13.4XXA
Use when ligament involvement is confirmed by imaging.

Cervicalgia

M54.2
Use for non-traumatic neck pain without specific muscle or tendon involvement.

Documentation & Coding Risks

Avoid these common documentation and coding issues when documenting Neck Strain to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code S16.1XXA.

Impact

Clinical: Inaccurate clinical picture, Regulatory: Non-compliance with documentation standards, Financial: Potential claim denials

Mitigation Strategy

Always document how the injury occurred, Use templates to ensure comprehensive documentation

Impact

Reimbursement: Incorrect coding may lead to claim denials., Compliance: Non-compliance with coding guidelines., Data Quality: Inaccurate clinical data representation.

Mitigation Strategy

Use S16.1XXA for traumatic neck muscle strains.

Impact

Failure to document specific muscles involved in neck strain

Mitigation Strategy

Use structured templates and checklists

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.

Emergency Department Visit for Neck Strain

Specialty: Emergency Medicine

Required Elements

  • Mechanism of injury
  • Specific muscles involved
  • Range of motion limitations
  • Pain assessment

Example Documentation

**HPI**: 34yo M presents with acute neck pain after [mechanism]. Reports immediate [pain location] exacerbated by [movement]. Denies radicular symptoms. **Exam**: - Tenderness: Palpable at right sternocleidomastoid muscle - ROM: Flexion 40° (nl 50°), rotation 60° bilaterally - Neurologic: Intact strength/sensation UE bilaterally **Imaging**: X-ray negative for fracture. MRI shows edema in right SCM muscle. **Assessment**: S16.1XXA - Acute strain right sternocleidomastoid muscle **Plan**: NSAIDs, physical therapy referral

Examples: Poor vs. Good Documentation

Poor Documentation Example
Neck pain after fall
Good Documentation Example
Acute strain left scalene muscles with 70% reduced lateral flexion following ground-level fall onto right shoulder. Positive tenderness on palpation of left anterior cervical triangle. X-ray negative for fracture.
Explanation
The good example specifies the muscles involved, mechanism of injury, and clinical findings.
