R22.0-R22.9Primary Range

Localized swelling, mass and lump of skin and subcutaneous tissue

Used for superficial masses without a confirmed diagnosis.

Benign lipoma

Used when a benign lipoma is confirmed by pathology.

Malignant neoplasm of connective and soft tissue

Used for confirmed malignant soft tissue neoplasms.

CodeDescriptionWhen to UseKey Documentation
R22.0Localized swelling, mass and lump, headUse for superficial masses on the head without confirmed diagnosis.
  • Physical exam indicating superficial mass
  • No deeper tissue involvement
D17.21Benign lipoma of right lower limbUse when a lipoma is confirmed by biopsy on the right lower limb.
  • Biopsy confirming lipoma
  • Imaging showing homogeneous fat-signal intensity

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 soft tissue mass

Essential facts and insights about Soft Tissue Mass

The ICD-10 code for a superficial soft tissue mass is R22.0-R22.9, depending on the location. For confirmed neoplasms, use D17 for benign or C49 for malignant masses.

Primary ICD-10-CM Codes for soft tissue mass

Billable Code

Decision Criteria

clinical Criteria

  • Mass is superficial and no deeper tissue involvement.

Applicable To

  • Superficial mass of head

Excludes

  • Deep masses

Clinical Validation Requirements

  • Physical exam indicating superficial mass
  • No deeper tissue involvement

Code-Specific Risks

  • Misclassification if mass is deeper than subcutaneous tissue.

Coding Notes

  • Ensure mass is superficial before using R22 codes.

Ancillary Codes

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

Nontraumatic hematoma of soft tissue

M79.81
Use if swelling is due to hematoma without trauma.

Differential Codes

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

Malignant neoplasm of connective and soft tissue of head, face and neck

C49.0
Use if biopsy confirms malignancy.

Malignant neoplasm of connective and soft tissue of lower limb

C49.2
Use if biopsy confirms malignancy.

Documentation & Coding Risks

Avoid these common documentation and coding issues when documenting Soft Tissue Mass to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code R22.0.

Impact

Clinical: Misdiagnosis risk due to lack of detail., Regulatory: Non-compliance with documentation standards., Financial: Potential for denied claims.

Mitigation Strategy

Always document depth in clinical notes., Use templates to ensure completeness.

Impact

Reimbursement: Incorrect DRG assignment leading to reimbursement issues., Compliance: Non-compliance with ICD-10 coding guidelines., Data Quality: Inaccurate clinical data affecting patient records.

Mitigation Strategy

Use C49 or site-specific codes if mass is deep.

Impact

Using R22 codes for deep masses can trigger audits.

Mitigation Strategy

Ensure documentation specifies mass depth and use appropriate codes.

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.

Benign Mass in Orthopedic Clinic

Specialty: Orthopedics

Required Elements

  • Size of the mass
  • Location
  • Imaging results
  • Pathology findings

Examples: Poor vs. Good Documentation

Poor Documentation Example
Mass on back, possible lipoma.
Good Documentation Example
4 cm soft, mobile, non-tender mass, mid-back, present ×6 months. Ultrasound shows homogeneous hyperechoic subcutaneous lesion. Probable lipoma (D17.2). Recommend excision if symptomatic.
Explanation
The good example provides specific details about the mass, imaging results, and a probable diagnosis.
