Is getting a skin spot biopsied covered by insurance?
Usually yes. A biopsy answers a medical question, so plans treat it as diagnostic care rather than cosmetic. Code 11102 is the charge for taking a thin slice off one spot and sending it out for testing. It is normally covered, it usually applies to the deductible, and the lab that reads the sample sends its own separate bill.
Usually
Diagnostic, but deductible applies
Two bills
The office bills 11102 for taking the sample. The lab bills 88305 for reading it. Patients see two charges from one appointment.
One spot per code
11102 covers a single lesion. Each further spot sampled that day adds an 11103 unit, and payers watch that count closely.
Deductible eats it
A biopsy is diagnostic, not preventive, so most high deductible plans pay nothing until the deductible is met and the negotiated fee lands on the patient.
Check first
One check before the appointment returns plan status, deductible left, and copay, so the desk can warn about both bills instead of one.
What would a real check show for this patient's 11102?
Pick a sample plan and type your per-biopsy fee. This is the visibility a real-time check gives the desk for every actual patient, in under a second.

Estimate from a sample plan. A real check reads the actual plan in under a second.
When 11102 is the right code
- A sample is taken to reach a diagnosis
- Shave technique, not a punch or full excision
- The tissue goes to a lab for reading
- One lesion per code, further spots use 11103
Documentation payers expect
The note should name the lesion, the reason for sampling it, and the technique used. Payers deny when the visit reads like a cosmetic removal instead of a diagnostic sample.
Why skin biopsies get denied
What happens after the biopsy
Two more charges usually follow. The lab bills its own line (88305) a few weeks on, and if the pathologist adds a special stain, 88342 appears beside it. If the result comes back cancer, the next visit is an excision (11602) or Mohs surgery (17311), each with its own deductible math. Quoting the office fee alone sets the patient up to feel misled, so a desk that pulls the plan numbers first quotes the whole picture.
11102, quick answers
Does insurance cover a skin biopsy?
Almost always, because it is diagnostic. What varies is the patient's share, since a biopsy applies to the deductible instead of being paid like preventive care.
Why did I get a second bill after my biopsy?
The office bills for taking the sample and the lab bills 88305 for reading it. Two bills from one appointment is normal.
Does Medicare cover a skin biopsy?
Yes, as a diagnostic service under Part B. The patient typically owes 20% after the Part B deductible, and the pathology read is billed on top of that.
What if two spots are sampled?
The first is 11102 and each further spot is 11103. Every line carries its own patient share.
Can the lab be out of network?
Yes. The office can be in network while the pathologist reading the sample is not, so it is worth confirming the plan's lab benefit before the appointment.
