14 of Dermatology Claims Are Rejected, We Know
Why.
Dermatology is a high-volume, high-complexity
specialtyand yet 14 of dermatology claims are
being rejected across the board. Why? Because
Dermatology Billing isnt being treated like its
own discipline. Most practices rely on billing
workflows designed for general medicine or
surgery, not the nuanced coding, modifier rules,
and payer behavior unique to dermatology. At MBC,
weve audited hundreds of dermatology practices
across the U.S.and we see the same patterns
again and again. Heres where those rejections
startand how we solve them. 1. Modifier Misuse
(Especially 25 and 59) Dermatology often involves
multiple procedures in a single visitsuch as a
lesion excision paired with a separate
evaluation. But billing those services without
the correct modifiers?

Why.

• Thats a fast-track to denial.
• Modifier 25 should only be used when the E/M is
  significant and separately identifiable from the
  procedure performed.
• Modifier 59 and its X-series counterparts are
  critical for unbundling servicesbut must be used
  with precision.
• Payers are cracking down on modifier abuse, and
  incorrect usage is one of the top reasons
  dermatology claims are rejected.
• 2. Poor Documentation for CPT Hierarchy
• Theres often confusion between procedures like
• Destruction of lesions (17000 series)
• Shaving (11300 series)
• Full excision (11400 series)
• Each of these carries different documentation
  requirements, and selecting the wrong code based
  on lesion type, location, or margins leads to
  undercodingor worse, denied claims.

Why.

• At MBC, we work directly with providers to ensure
  your clinical documentation supports the CPT code
  submitted. We also offer proactive audits to spot
  misalignment before the payer does.
• 3. Lack of Dermatology-Specific Coding Knowledge
• Dermatology coding goes deeper than the basics
• Skin biopsies require accurate site documentation
  and lesion counts.
• Phototherapy billing changes based on type and
  number of sessions.
• Mohs surgery requires layer-by-layer detail and
  correct staging codes.
• A generalist billing team may not know these
  nuancesbut your revenue depends on them.
• 4. Missed Opportunities in Hybrid Coding
  (Cosmetic Medical)
• Many dermatology practices offer both medical and
  cosmetic services. But when these arent coded
  and segmented correctly
• Revenue reporting becomes skewed
