Are cortisone shots for skin covered by insurance?
Usually yes when there is a medical reason. Code 11900 is the charge for a steroid injected straight into a skin problem, such as a keloid scar, a painful acne cyst, a thick patch of eczema or psoriasis, or a bald patch from alopecia areata. One line covers as many as seven spots, and the medicine itself bills separately.
Usually
Covered for a medical skin problem
Up to 7 spots
One 11900 line covers one to seven lesions injected. Eight or more moves the visit to 11901, no matter how many needle sticks it took.
Drug bills apart
The injection code does not include the medicine. The steroid is its own line, often J3301, billed in units of ten milligrams.
Alopecia trap
Some plans call injections for hair loss cosmetic and deny them, while paying for the same shot into a keloid or a psoriasis patch.
Lesions, not shots
Payers count lesions, not needle sticks. One check before the visit gives the desk plan status, deductible left, and the copay for the day.

When 11900 is the right code
- Medicine is injected into the lesion itself
- Seven or fewer lesions treated that day
- A medical diagnosis such as keloid or psoriasis
- The drug is billed on its own separate line
Documentation payers expect
The note should name the diagnosis, the lesions injected and their count, and the drug with the number of units given. Any wasted drug is documented separately when the payer asks for it.
Why intralesional injections get denied
What happens after the injection
Most of these are a series, not one visit. Keloids and thick patches are often injected again every few weeks, and each session bills 11900 plus the drug line again, so a copay that felt small multiplies. If a spot is injected and still does not settle, the next step is often a sample sent for testing, with its own lab charge behind it. Knowing the copay, deductible, and plan status before the first shot lets the desk quote the whole series.
11900, quick answers
Does insurance cover a cortisone shot into the skin?
Most plans cover it when the note shows a medical problem such as a keloid, a painful cyst, or a stubborn psoriasis patch.
Why is there a separate charge for the medicine?
The injection and the drug are two different codes. The steroid is billed by units, often as J3301, on its own line.
Does Medicare cover 11900?
Medicare contractors generally pay it for documented conditions such as keloids or psoriasis, with the drug billed separately in units. Coverage for hair loss injections varies, and the patient owes the usual 20% after the Part B deductible.
How many spots does one charge cover?
As many as seven lesions in a session. Eight or more moves the whole visit to 11901.
Are injections for hair loss covered?
It varies. Some plans pay for alopecia areata injections and others exclude them as cosmetic, so the plan is worth checking before the visit.
