R22-R23Primary Range
Localized swelling, mass and lump of skin and subcutaneous tissue
This range includes codes for localized swelling, specifically R22.41 for the right lower limb and R22.42 for the left lower limb.
Edema, not elsewhere classified
This range includes codes for edema, such as R60.0 for localized edema, which can be used for non-traumatic swelling.
Dislocation, sprain and strain of joints and ligaments at ankle, foot and toe level
This range includes codes for ankle sprains, such as S93.401A, which are relevant when swelling is due to trauma.

Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting Ankle Swelling to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code R22.41.
Impact
Clinical: Leads to incorrect diagnosis coding., Regulatory: Non-compliance with documentation standards., Financial: Potential for denied claims.
Mitigation Strategy
Always document laterality in clinical notes., Use templates to ensure completeness.
Impact
Reimbursement: Incorrect coding can lead to denied claims., Compliance: Non-compliance with coding guidelines., Data Quality: Inaccurate clinical data representation.
Mitigation Strategy
Use R22.41 for unilateral swelling with a palpable mass.
Impact
Using non-specific codes for ankle swelling.
Mitigation Strategy
Ensure documentation supports specific code selection.
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.
