Can someone clarify the difference between a primary and secondary achilles repair (27652 vs 27654)?

Supercoder says that a secondary repair, 27654 is when "The provider performs repair of Achilles tendon for the second time with or without use of graft because the previous one was unsuccessful or the patient reinjured the tendon."
But I read elsewhere that a primary repair is when the injury is acute, and a secondary is when the condition is chronic.

I’m trying to code for a patient who injured her achilles over a year ago but hasn’t had it repaired before. So is it primary because this is her first repair, or secondary because the condition is chronic??

Thank you for your help!!
