CodeDescriptionWhen to UseKey Documentation
Z89.512Acquired absence of left leg below kneeUse for documenting the status of a patient with a left below-knee amputation.
  • Documentation of amputation level and laterality
  • Presence of prosthetic device if applicable
0Y6M0Z4Detachment at right 4th ray, completeUse for surgical documentation of complete ray amputations.
  • Surgical report specifying complete ray detachment

Clinical Decision Support

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

Decision Criteria

documentation Criteria

  • Presence of detailed surgical notes specifying amputation level and laterality.

Applicable To

  • Below-knee amputation

Excludes

  • Congenital absence of limb

Clinical Validation Requirements

  • Documentation of amputation level and laterality
  • Presence of prosthetic device if applicable

Code-Specific Risks

  • Omitting laterality
  • Not documenting the presence of a prosthesis

Coding Notes

  • Ensure to document the specific level and laterality of the amputation.

Ancillary Codes

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

Type 2 diabetes mellitus with diabetic peripheral angiopathy with gangrene

E11.51
Use to document the underlying condition leading to amputation.

Differential Codes

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

Complete traumatic amputation at knee level, right leg, initial encounter

S88.011A
Use for traumatic amputations during the acute phase.

Detachment at right 4th ray, partial

0Y6M0Z7
Use when only part of the ray is amputated.

Documentation & Coding Risks

Avoid these common documentation and coding issues when documenting Amputation to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code Z89.512.

Impact

Clinical: Leads to vague clinical documentation., Regulatory: Non-compliance with coding standards., Financial: Potential for reduced reimbursement.

Mitigation Strategy

Always verify the specific level and laterality before coding., Use detailed surgical reports to guide coding.

Impact

Reimbursement: Claims may be denied or delayed., Compliance: Non-compliance with coding standards., Data Quality: Inaccurate patient records.

Mitigation Strategy

Always specify the side of the body affected by the amputation.

Impact

Reimbursement: Potential for reduced reimbursement., Compliance: Risk of audit failure., Data Quality: Compromised data integrity.

Mitigation Strategy

Use specific codes that detail the level and laterality of the amputation.

Impact

Risk of audits due to lack of specificity in documentation.

Mitigation Strategy

Implement regular training for staff on documentation requirements.

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.

  • Residual Limb Condition
  • Prosthesis Details
  • Functional Status

Examples: Poor vs. Good Documentation

Poor Documentation Example
Amputated leg.
Good Documentation Example
Left transtibial amputation at mid-shaft of tibia/fibula (8/2024) due to E11.51. Residual limb measures 22 cm from patellar tendon with 3 cm edema. Uses Fillauer Formula TF socket with Unity vacuum system.
