Plantar Fasciitis Treatments — CPB 0235 | AETNA Coverage Update

TL;DR: Aetna, a CVS Health company, modified CPB 0235 governing plantar fasciitis treatments, effective September 26, 2025. Here's what billing teams need to do before claims start hitting the new criteria.

This update to the Aetna plantar fasciitis coverage policy touches CPT codes 20550 and 29893 — the two codes that actually get paid — while locking out a long list of procedures under the not-covered bucket. The policy draws a hard line between conservative-failure pathways and experimental treatments. If your practice bills for PRP injections (CPT 0232T), extracorporeal shock wave therapy (CPT 28890), or acupuncture (CPT 97810–97814) for plantar fasciitis, this coverage policy directly affects your reimbursement.

Aetna Plantar Fasciitis Coverage Criteria and Medical Necessity Requirements 2025

CPB 0235 defines two covered pathways for plantar fasciitis treatment. Both require documented conservative therapy failure — and Aetna is specific about what "conservative" means.

For CPT 20550 (injection, single tendon sheath or ligament/aponeurosis), Aetna requires that the patient has failed conservative treatments first. The policy cites stretching exercises, over-the-counter silicone heel shoe inserts, and two to three weeks of NSAIDs as examples of conservative therapy. Your documentation needs to show a clear pattern of conservative care that has failed. A denial based on weak or absent conservative therapy documentation is avoidable — and common.

For CPT 29893 (endoscopic plantar fasciotomy), the bar is higher. The patient must have intractable plantar fasciitis or heel spur syndrome AND must have failed a full six-month trial of conservative therapy. Six months. Not "several weeks of PT." If your documentation shows four months of conservative care, Aetna will deny the surgery as not meeting medical necessity, regardless of the clinical picture.

The real issue here is documentation sequencing. Medical necessity under this coverage policy isn't just about the diagnosis — it's about proving the timeline. Your chart notes need to show when conservative therapy started, what was tried, and when it failed. Without that timeline, neither CPT 20550 nor CPT 29893 will clear.

Prior authorization requirements aren't explicitly detailed in this policy revision, but endoscopic plantar fasciotomy at CPT 29893 carries enough financial exposure that you should verify prior auth requirements with Aetna before scheduling. For commercial plans, prior auth for surgical procedures is standard. Don't assume the policy criteria alone are sufficient — check the member's specific plan.

Aetna Plantar Fasciitis Exclusions and Non-Covered Indications

This is where CPB 0235 gets expensive if you're not paying attention. Aetna classifies a wide range of plantar fasciitis treatments as experimental, investigational, or unproven. These aren't gray-area codes — they're hard denials.

PRP and autologous injections are not covered. CPT 0232T (platelet rich plasma injection) and CPT 0481T (autologous white blood cell concentrate/autologous protein solution) are both in the excluded bucket. HCPCS P9020 (platelet rich plasma) and amniotic tissue products Q4139 and Q4155 fall here too. If you're billing PRP for plantar fasciitis under any Aetna plan, stop and reassess. Those claims will deny.

Extracorporeal shock wave therapy (CPT 28890) is not covered. This one surprises practices that have billed it successfully under other payers or in other clinical contexts. Under CPB 0235, Aetna treats it as experimental for plantar fasciitis. Same with low-level laser therapy (HCPCS S8948) and ultrasound therapeutic application (CPT 97035).

Dry needling (CPT 20560 for one to two muscles, CPT 20561 for three or more muscles) is excluded. So are trigger point injections (CPT 20552, CPT 20553) when billed for this indication.

Acupuncture across CPT 97810 through 97814 is not covered under this policy. Botulinum toxin chemodenervation (CPT 64642 through 64645, with HCPCS J0585, J0586, J0587, J0588) is excluded. Radiofrequency-based nerve destruction (CPT 64640) is out.

Surgical alternatives carry important nuances. Open fasciotomy procedures — CPT 28008, 28060, 28062, and 28250 — are listed as "Other CPT codes related to the CPB" with a specific notation: not covered when guided by ultrasonic energy. That language matters. If you're billing ultrasound-guided open fasciotomy, Aetna's position is clear.

Radiation treatment delivery codes — CPT 77401 through 77417 and HCPCS G6001 through G6014 — are in the excluded group. Low-dose radiation for plantar fasciitis isn't a common billing pattern in the U.S., but if your facility has explored it, this policy shuts that door.

Vascular embolization (CPT 37243) for plantar fasciitis is also excluded. Kinesio taping, local ozone injection, and the TenJet system fall into the same not-covered group — confirmed by the HCPCS groupings in the policy.
