Billing tips

Bill 21087 only for the impression and preparation phase, not the final prosthesis delivery (which may be coded separately with other CPT or HCPCS codes)
Impact: Prevents unbundling issues and potential overpayment recoveries; ensures proper sequencing of prosthetic fabrication billing that can exceed $3000 total across all phases
Document the medical necessity thoroughly, including the cause of nasal defect, failed or inappropriate surgical reconstruction attempts, and functional/psychological impact
Impact: Reduces denial risk by 60-70%; Medicare and commercial payers frequently deny prosthetic services coded as cosmetic without clear reconstructive documentation
Submit claims to non-facility setting when performed in physician office or clinic to capture the $293.71 differential ($1555.22 vs $1261.51)
Impact: Direct revenue impact of $293.71 per procedure; verify place of service code 11 for office vs 22 for outpatient hospital
Coordinate with prosthodontist billing for final fabrication to avoid duplicate billing; 21087 covers surgical impression only, not laboratory fabrication work
Impact: Prevents compliance issues and audits; laboratory work typically billed separately with HCPCS L-codes worth $1500-3000
Use modifier 22 with supporting documentation when dealing with post-radiation tissue changes or severe scarring that significantly increases procedural time beyond 60-90 minutes
Impact: Potential additional reimbursement of $311-466 (20-30% increase) when properly documented with time logs and complexity explanation
Verify that the treating diagnosis code clearly indicates the nasal defect and its cause (cancer, trauma, congenital) as primary diagnosis, not just the prosthetic fitting

Frequently asked questions

What is the Medicare reimbursement rate for CPT code 21087 in 2025?

The 2025 Medicare national average reimbursement for CPT 21087 is $1555.22 in non-facility settings and $1261.51 in facility settings. These rates are based on 48.08 total RVUs multiplied by the 2025 conversion factor of 32.3465. Actual payment may vary based on geographic locality adjustments.

Does CPT 21087 include the actual fabrication of the nasal prosthesis?

No, CPT 21087 covers only the impression taking and preparation work performed by the surgeon or prosthodontist. The actual laboratory fabrication of the prosthesis is typically billed separately using HCPCS L-codes or other appropriate codes for the prosthetic device construction and delivery.

Can CPT 21087 be billed on the same day as a nasal resection surgery?

Generally no, as impression for prosthesis is typically performed after surgical healing is complete (6-12 weeks post-resection). If billed during the global period of the resection surgery, modifier 78 or 79 may be required, which will reduce reimbursement. Most payers expect this as a staged procedure separate from the resection.

What diagnosis codes support medical necessity for CPT 21087?

Appropriate diagnosis codes include malignant neoplasms of nasal structures (C44.301-C44.321), traumatic nasal defects (S02.2, S01.2), congenital nasal abnormalities (Q30.0-Q30.9), and sequelae of disease like leprosy or Wegener's granulomatosis causing nasal destruction. The diagnosis must demonstrate a structural defect requiring prosthetic rehabilitation.

How many RVUs is CPT code 21087 worth in 2025?

CPT 21087 has a total of 48.08 RVUs in 2025, broken down as: 24.88 work RVUs, 20.82 non-facility practice expense RVUs (11.74 facility PE RVUs), and 2.38 malpractice RVUs. This relatively high RVU value reflects the complex, time-intensive nature of custom prosthetic impression work.

What specialists typically bill CPT code 21087?

CPT 21087 is most commonly billed by maxillofacial prosthodontists, plastic and reconstructive surgeons, head and neck surgeons, otolaryngologists (ENT specialists), and oral and maxillofacial surgeons who specialize in facial prosthetic rehabilitation. The provider must have specialized training in facial prosthetics.

Is prior authorization required for CPT 21087?

Prior authorization requirements vary by payer. Many Medicare Advantage plans and commercial insurers require prior authorization for prosthetic services including 21087. Traditional Medicare typically does not require prior auth but does require clear medical necessity documentation. Always verify payer-specific requirements 2-3 weeks before the scheduled procedure to avoid denials.
