CodeDescriptionWhen to UseKey Documentation
M79.631Pain in right forearmUse when the patient presents with non-specific pain in the right forearm without any identifiable injury.
  • No fracture or dislocation on imaging
  • No neurological deficits
  • Negative Tinel’s/Phalen’s tests
M79.632Pain in left forearmUse when the patient presents with non-specific pain in the left forearm without any identifiable injury.
  • No fracture or dislocation on imaging
  • No neurological deficits

Clinical Decision Support

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

Ancillary Codes

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

Chronic pain due to trauma

G89.21
Use when chronic pain management is required due to a past traumatic event.

Other chronic pain

G89.29
Use when chronic pain management is required for non-traumatic causes.

Differential Codes

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

Contusion of right forearm, initial encounter

S50.81XA
Use if there is a documented mechanism of trauma and physical signs of contusion.

Contusion of left forearm, initial encounter

S50.82XA
Use if there is a documented mechanism of trauma and physical signs of contusion.

Documentation & Coding Risks

Avoid these common documentation and coding issues when documenting Forearm Pain to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code M79.631.

Impact

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

Mitigation Strategy

Always ask and document how the injury occurred., Include detailed patient history in the notes.

Impact

Reimbursement: May lead to denied claims due to lack of specificity., Compliance: Non-compliance with ICD-10 coding guidelines., Data Quality: Reduces the accuracy of clinical data.

Mitigation Strategy

Always specify laterality by using M79.631 or M79.632.

Impact

Failure to document laterality can lead to audit findings.

Mitigation Strategy

Implement a checklist to ensure laterality is documented in all cases of forearm pain.

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.

Non-specific forearm pain in an occupational setting

Specialty: Occupational Health

Required Elements

  • Subjective: Pain description, duration, and aggravating factors.
  • Objective: Physical examination findings, including tenderness and range of motion.
  • Assessment: Diagnosis with ICD-10 code.
  • Plan: Treatment plan and follow-up.

Example Documentation

Subjective: 45M construction worker reports 3/10 aching pain in left forearm worsened by gripping tools. Denies trauma. Objective: No swelling/deformity. Tender 2cm distal to lateral epicondyle. Grip strength 20% weaker vs. right. X-ray negative. Assessment: Chronic left forearm pain (M79.632) likely related to repetitive use. Plan: Activity modification and NSAIDs.

Examples: Poor vs. Good Documentation

Poor Documentation Example
Forearm pain, recommend rest.
Good Documentation Example
Right forearm pain (M79.631) with tenderness over brachioradialis. Work restrictions: No lifting >10 lbs.
Explanation
The good example specifies laterality, includes a detailed assessment, and provides a clear plan.
